I don't think it is calcium either ....so the million dollar question is what is causing it! I'm starting to pull my hair out on this one.

Good plan chem geek I'll give it a whirl. Still concerned with the grout which seems to be getting soft, still can't tell for sure if it is build up on the grout or the grout it self getting soft and dissolving . That is the reason I lowered the CH to 350 just in case it was calcium build up.

Thanks chem geek...my ph does rise steadily. Partially due to my SWG I assume. I need to add acid weekly as the PH rises from 7.4 to 8 in that time with a TA around 80 to 90. If I drop my TA to the lower end around 60 would this slow the PH rise. What are the negatives to maintaining the TA on...

Ok I have reduced my CH down to 350. My next question is about TA. I have reduced it down to 100 by acid/ aeration. But when running the numbers with the pool calculator it seems my CSI would be better off with TA of 100 than 80. What is your recommendation on is? FC 5.5 PH 7.5 CH 350 CYA 40...

Thanks ping that seems to similar to my problem. To give a little more history on my situation the pool is nearly 1 year old and I have maintained it from the beginning. Over the last few months my CH has crept up from 350 to 400 and I have been trying to lower it with new fill water which is...

What ever it is calcium or salt it seems to be affecting / depositing only the grout and not the tile themselves. It almost seems like grout is getting soft and dissolving. I'll lower the CH and monitor the PH and hope for the best. I don't think it is salt though as the tiles are always covered...

Here is a picture of the pool for reference and a screen shot of the pool calculator.

Hi, I am noticing some problems with the grout in my 1 year old pool. My pool is a concrete pool covered entirely in 4" tiles with grout in between.When I rub the grout even with my finger if feels slightly slick and I get quite a bit of white flaky powder coming off the grout. I spent a day...

I think it is a case of me paying too much attention! From the photo of the product in that link you can see it says bromine. That is what I couldn't understand. Now I get it ....it must just be the wrong picture for the product.

I have a salt water pool and just finished following the procedure from this forum to add 20 mule team borax. When I went to test the borate concentration I used the test strips i had gotten for this but at the time I didn't realize I bought bromine test strips which don't do me any good. What I...

I realize this thread is from a few years ago but the link in the first post for the test strips on amazon looks like a test for bromine not borates. From lamottes web site below it seems these wont work for testing borax levels? http://www.lamotte.com/en/pool-spa/insta-test/2976.html I am...

John, I am a fairly new pool owner myself and have been using the ColorQ Pro 7 test kit also. IT seemed to work great for the first month or so but now my reading are becoming increasingly untrustworthy. Alot of time i find myself repeating the same test several times in a row to come up with a...

Re: Fiber Clear or Zeofiber Bodarville, I used fiberclear for the first time to top coat my sand filter. It seemed to work pretty good, it didn't get rid of all the floaters in the water seen in the lights at night but it did clear it up some. My biggest question is about backwashing. Is all...

How many minutes is the suggested backwash time? I did it 2x at about 3 minutes each time. I have a sight glass on the drain line which showed clean water. The top cap on top of the filter is see through and that water never cleared up completely but I didn't what to pump too much water away...

That was my biggest worry is that the fiber did not get flushed out on the backwash. The fiber top coat seemed to help clean the pool water up quite a bit but since it was still on top after the backwash i am hesitant to keep using it. I guess this isn't very common for people to use huh? I am...

I have a 28" jesta sidemount sand filter. I had heard that by putting in a bit of cellulose fiber ( fiber clear) that it would help to filter out the smaller particles in my pool similar to adding some DE to a sand filter. Anyway I followed the directions and added enough fiber to increase my...

Thanks bobodaclown iThat is a sound plan I'll give it a try next time and see how it goes

Rthorntn, I have the zodiac tri myself and was considering upgrading to he PH model. How has that been working for you so far? I have heard a lot of bad reviews about the acid injection on those but I would make my life a lot easier

My biggest worry is I am gone sometimes for 3 weeks at a time and the wife is left minding the pool. She isn't comfortable adding acid so I am worried the PH will get to high while I am gone. I was actually thinking about adding the"PH" system to my zodiac tri but have heard that it isn't...

I don't think it is algae it's not green and doesn't smudge some of the worst spots are more yellow but most are just dirty brown. Like I said the only way I have found is to scrub it with an oversized grout tooth brush and without scuba gear it is nearly impossible to do!

Ok so I have been able to successfully lower my ALK/PH with acid and bring the PH back up with aeration ( mainly running the built in spa jets in the pool). My question is will running the spa continue to raise the PH? Basically what I mean once I get the ALK in the proper range will I risk...

I hope these pics uploaded. I think the grout is just dirty from the pool not being vacuumed enough but very hard to clean and get bright white again have to use a small brush and scrub the buck outta it

To help control the ph and I've heard many people praise how their pool looks and feels better with them. Do you disagree Casey?

My grout keeps getting dirty and the only way I can clean it is with a small brush and a lot of elbow grease. This isn't too bad in the shallow end but nearly impossible in the deep end. Any tips or tricks to getting this grout back to white and keeping it that way would be greatly appreciated...

Zea3, I used the pool calculator to determine the amount of calcium chloride to add, according to the numbers I have added about 3 kgs over recommended to get up to 300 with only a slight increase on the reading. I will wait a few days before adding more I don't want to over do it. I got my ALK...

I am learning a lot from this forum and have gotten my pool in just about perfect shape. I a just about ready to do the borax treatment but I have been battling my Alk. I have finally gotten it down to about 80... It seems like it stabilizes a round 120 or so. When I do the acid and aerate it...
