    Ready to Convert - am I?

    Am ready to convert…

    First, sorry for the long post but I feel I need to provide history in case others have experienced similar.

    I am in my second year of a Baquacil, in-ground 18x36 liner pool. I think about 27,000 gallons of water (18x36 - 42 inch shallow, 100 inch deep). I use a sand filter. Built and opened in July 2007. Water was crystal clear for about 6 weeks back then and then turned hazy. Fought with it most of the end of August and into September and October. At the advice of my pool specialists, I used Floc a few times, added 2 gallons of Oxider every 3 or 4 days, did an initial dosing of Algecide, etc to try to get it clear. Didn’t come close and ended up closing the pool for the winter mid October (live in Grand Rapids, Michigan).

    Opened the pool this year Memorial Day weekend. Water was a medium green color and could not see my drains in the deep end. Had water tested. Total Alkalinity is 125, Calcium Hardness is 225, PH 7.6, Copper 0, Iron 0. Pool specialist told me all levels were good so I added startup dose of Algecide, Oxidizer. After a three or four days, pool went from Green to Grayish to Very Hazy. Filter runs 24x7, backwashed when pressure in return lines was minimal. After 9 days pool got to Slightly Hazy (meaning I could see the drains now but barely). I was told to Floc it - which I did and vacuumed to waste. That seemed to make it more clearer but it was still very hazy. After about 2 weeks since opening I was told to add DE to the skimmer (??? – don’t remember if this is what is was but it was a white powder and I was told it was a filter aid). I did this. Here is where it gets weird and ended up clearing up very nicely. I am not sure what did it but it cleared up. The day I added the DE (or whatever it was) the pressure in the sand filter went up from about 16 PSI (where it normally runs) to about 22 PSI. Pool specialist told me this was normal and to not backwash for 12 hours unless pressure goes up further when at that point to “bump” the filter lever to relieve a little bit of the pressure. That evening we had a tremendous downpour of rain, actually had 4+ inches in just over 2 hours. Needless to say, my water level rose up so I went to check the filter PSI. I was at 24 PSI so I decided to backwash: one - to relieve the pressure, two – to drain some water. I backwashed for about 3 or 4 minutes until water level was just over half way up the skimmer. Turned to filter and went back inside. I happened to look out at the pool about 4 hours later and noticed the water level way below the skimmer! Yikes! I went outside (mind you it was pouring rain again) and couldn’t see much since it was dark and decided to just shut the filter off for the night. The next day I went out and tried turning on the filter again. I had it set to Filter but could hear and see a trickle of water coming out of the backwash/waste line. I tried different filter settings and the Recirculate setting also had a trickle. I determined that the night before, while the setting was on Filter that the water slowly drained out to below the skimmer. I researched online and took the top off the Sandfilter and found that a rubber gasket was dislodged and not lined up. I lined it up and put it back together and turned it back on and voila, no leaks! In the meantime, I put my house hose into the pool to get water level back up. When I looked at the pool low-and-behold the water was crystal clear! So, a weird sequence of events but I was happy I got to clear water! That was about June 8th or so, 3 weeks after opening the pool.

    Fast forward now to July 20th. Since June 8th I’d been maintaining Baqua Sanitizer level (between 40 and 50 ppm). I did weekly maintenance of 8 oz of Algecide and a ½ gallon of Oxidizer. Water temperature was between 78 and 81. Never needed to vacuum much as water was crystal clear. Two weeks ago we had air temperatures in the upper 80s, low 90s, high humidity for about a week straight. Pool water temperature went up to 86 or 87 (I stopped using the solar cover when the water temp hit 83). About 10 days ago the water started to get a wee bit hazy. I’d add a ½ gallon of Oxidizer and the next day no reading on my test strip. I added the full start up dose of 2 gallons, again, less than 24 hours and the reading was nothing. For the past 10 days I’ve been adding 2 gallons of Oxidizer every other day and always the next day when I took a reading it showed zero. Keeping in mind that every day the water was getting more and more hazy. Baqua Sanitizer still between 40 and 50 ppm. About a week ago I did an initial start up dose of Algaecide even though there was no visible signs of algae growth. Yesterday I went to my pool specialist to get more Oxidizer and we got to talking about my scenario. He told me to add 3 pounds of a non-chlorine granular shock (from Poollife) before I add the Baquacil Oxidizer. I did that last night and this morning when I woke up, BAM – pool is no longer hazy but light GREEN! I just went out this morning and added another full initial start-up dose of Algaecide and dumped in the two gallons of Oxidizer to see if that will do anything.

    Here is my question and dilemma. I have a party on August 16th, 3 weeks from now. I am leaving for a 10-day vacation 9 days from now. I’ll return to my home on August 10th or 11th. I am ready and willing and want to convert to Chlorine. Should I do it now knowing I have to leave for vacation on July 19th (9 days from now)? Should I wait and keep throwing Oxidizer and Algeacide (and money) at the pool hoping it clears? Should I wait and convert on August 10th when I return?

    Current levels:
    Baquacil: 40 ppm
    pH: 7.6
    Oxidizer: 0
    Copper: 0
    Iron: 0
    Total Alkalinity: 120
    Calcium Hardness: 225

    Conversion:

    Do I need to adjust any levels above before starting?

    From reading the posts I think I need to maintain 10 ppm of Free Chlorine (FC). Should/can I do 15 ppm with a liner pool?

    I think I have 27000 gallons of water so I will start out with 560 oz of bleach (6%) - unless I can do 15 ppm then I need to add 840 oz. How often do I add this amount, about every hour depending on the FC level? I work during the day but my wife can add as necessary.

    I think I need to add it to the skimmer directly, run filter 24x7, backwash when pressure is high enough to impead circulation.

    Anything else I am forgetting?

    The direction I am looking for is whether my thoughts on Conversion Process are correct, and WHEN should I start - now or on August 10th?

How often do I add this amount, about every hour depending on the FC level? I work during the day but my wife can add as necessary. It'll plummet like a hot rock when you first start so be prepared to add another dose within hours of your first dose.....It'll get less frequent as time goes on. You cannot possibly have too much on hand.

    I think I need to add it to the skimmer directly, run filter 24x7, backwash when pressure is high enough to impead circulation. That's correct
    Anything else I am forgetting? You'll have to change the sand when your conversion is complete.

    The direction I am looking for is whether my thoughts on Conversion Process are correct, and WHEN should I start - now or on August 10th? That's really tough. Most conversions take about 10 days. Yours' may happen in five days or fifteen days. You've got some timing roadblocks whichever you choose so you'll have to decide.

    While your contemplating your decision, read the articles in pool school. You've been adding a bunch of chemicals that are unneccessary. YOu will be able to have sparkling water with almost nothing but chlorine once you get your conversion complete.

    Re: Ready to Convert - am I?

    There is a complete description of how to do a conversion here.

    9 days and then a vacation sounds pretty difficult, but possible with lots of effort and a little luck. If you can get the bulk of the conversion done in the first week you should be able to use a trichlor floater during the vacation, but it is going to take diligence and some luck to have everything work out just right.

    For the first day or two you will likely be adding 6 1/2 gallons of 6% bleach as often as every hour, so buy plenty.

    Do you have a FAS-DPD chlorine test? You are going to need one after the first few days.

    Re: Ready to Convert - am I?

    I just got back from Costco with 80 gallons of Bleach. I'll go back as often as I need to. The 80 gallons only cost me $110 which is the amount I spent on Baqua-**** just this past week alone! I ordered an FAS-DPD tester, this one. I actually met a stranger in the store who asked me if I was burying people or shocking a pool! He was actually a pool guy - tried to convince me to buy pool chlorine instead of bleach but no go. He wasn't surprised I was having troubles with Baquacil.

    I'm ready now, worst case I start over again when I get back. My kids are at summer camp this week so only the wife and I will miss swimming in the pool.

    I'm off to add my first 6.5 gallons! I'll be taking photos hourly and posting chemical levels the best I can. I only have a strip test kit that reads up to 10 ppm FC and TC but until my FAS-DPD kit arrives I have choice.

    Re: Ready to Convert - am I?

    3:25 Readings: (remember I have test strips until my kit comes)
    Total Chlorine: 2
    Free Chlorine: 0.5
    Total Alkalinity: 120
    pH: 8.4+ (8.4 on my test strip is a pink color, the color test was more pink that so I guess 8.4+)

    Do I keep adding 6.5 gallons every half hour or wait it out to every hour? Pool only turned mustard yellowish and very cloudy. I was expecting more dramatic color changes. Too early to experience that?

    Keep at it. The first couple of cycles can probably be done every half hour. If the FC level is 5 or more after half an hour then switch to hourly.

    Seems like FC only stays up there for less than 5 minutes. Can I possibly add too much bleach? Keep adding every half hour?

    Re: Ready to Convert - am I?

    You are doing great!

    It takes 20 to 30 minutes for all of the water to mix throughly, thus the delay between additions.

    You don't want the FC level going much above 15, even for short periods. That is why you only add 6 1/2 gallons at a time.

    OK, got it! I thought I would be able to maintain 15 ppm constantly throuhout the entire time, even in the beginning. I just dosed again but I just got called away to go to Batman Dark Night so now I can't dose for for 3 hours!! Will I lose momentum? Also, should I dose every hour all night? Finally, thanks for the encouragement, I appreciate the support and motivation.

    You can take a break any time as long as you add bleach at least twice a day. The more frequently you add bleach the sooner the conversion will be done.

    Re: Ready to Convert - am I?

    Ok, just got back from the Dark Knight - awesome! It is dark here in Michigan but I turned on the outside light around the pool and see a tremendous amount of Baqua-scum floating on the surface - HOORAY!! Filter pressure was way up so I backwashed and then added 6.5 more gallons. Did not check levels but will do so in the morning. Will take a picture then too. Thanks for all the help so far!

    Re: Ready to Convert - am I?

    Couldn't wait until morning for reading.
    10:10 PM Added 6.5 gallons

    30 minutes after adding 6.5 gallons:
    Total Chlorine: 8.0
    Free Chlorine: 5.0
    Total Alkalinity: 120
    pH: 8.4+

    Calm evening, can smell lots of chlorine around the pool area. Still lots of Baqua-scum on surface. Should I skim the scum off the top with my leaf skimmer screen?

    I'll take another reading before heading of to bed for the night...stay tuned.

    Re: Ready to Convert - am I?

    Skimming helps speed up the process, but isn't absolutely required.

    You are clearly making progress, FC didn't go to zero!

    Re: Ready to Convert - am I?

    This morning there was not as much as the Baqua-scum on the surface. I'm assuming it either was skimmed up or dropped to the pool bottom? Can't see the bottom so I can't tell you. I do notice that in and around the skimmer opening and my steps yellowish, pollen-like sediment. Can't see it real well in the pictures but it is there. I backwashed in the middle of the night once and when I got up at 6:30 this morning. Both times pressure was really high (5-6 PSI higher than normal operating pressure).

    When should I start vacuuming and scrubbing walls and such?

    Took reading when I woke up.
    Total Chlorine: 1.0
    Free Chlorine: 0.0
    Total Alkalinity: 120
    pH: 7.6

    6:55 AM Added 6.5 gallons

    3 minutes after adding 6.5 gallons:

    Total Chlorine: 10.0+
    Free Chlorine: 10.0+
    Total Alkalinity: funky color
    pH: 8.4+

    I am off to work today so my lovely wife is taking over. I'll be posting numbers as she calls them in to me. She'll be taking photos but I'll be posting them when I get home from work.
