You'll remember this photo from my equipment post:


Nothing pretty here.
I turned on the pump without the filter and let it circulate for a few hours. Initial numbers had the pH above 8.6 and TA around 80. I put in around 100oz of acid and got the pH down to 7.5. That didn't fit it. :p




4/30/2016 2:00 PM
FC 0
CC 0
pH 7.5
TA 100
CYA 0

I added 4 gal 10% bleach and waited 15 min
4/30/2016 2:15 PM
FC 18
CC 1

More waiting and some backwashing
4/30/2016 3:45 PM
FC 12.5
CC 1

More waiting, more backwashing. Something is definitely happening in there. Many tadpoles lost their lives this day.
4/30/2016 6:00 PM
FC 11
CC 1
TA 80

At this point, I need to add some water (from a well) to compensate for all the backwashing. I also don't want to stay up all night with this baby, so I decided to up the chlorine a bit, set the filter speed to medium and call it night. It's raining, if that matters.
4/30/2016 9:45 PM Added 1.5 gal 10% bleach.

Welcome and good morning. I hope you had a good evening. One thing you might want to look at is scooping out as much solid stuff if you haven't already done that.

Also what is your CYA number. I see you have it listed as 0. You need to have around 30 so the chlorine isn't eaten by the sun.

You're on the right track, and it will just take some patience an Chlorine. I'd add enough Cya to get you to 30 PPM and just keep pouring the Bleach to it. Have you scooped the bottom for leaves and other debris that might be there?

I haven't added any CYA yet, it is overcast and miserable, so I don't think the sun is much threat, but I will get it up to 30 today.
I have been scooping and sweeping throughout. My back is killing me today. 600# of pebbles and sand might have contributed. But things are definitely looking better. I'll try to figure out the vacuum today too, I can tell there are 'deposits' on the bottom that disintegrate when the net touches them, maybe the vac will get it out.
Here are the numbers from this morning.

Should I be dealing with this pH? Or just let it ride until the SLAM is over?

FC 13
CC 0.5
pH 8.2
TA 130

pH is reading high because your FC is above 10. If you set the pH before you started your SLAM, you are fine. Just continue the SLAM until you are done. pH reading will be accurate again one the FC drops below 10.

I didn't take another pic this morning because I thought it looked about the same, but in reviewing the pics here....It actually looks better than that now, so...sorry!

But here's the numbers from this morning:
FC 10
CC 1.5

I put in another gallon and a half to get it through the day (some people gotta work) and then gave it a quick brush down.

Oh, and I wasn't able to deliver on the CYA yet. That stuff is REALLY stubborn to dissolve!

A huge branch broke off the tree that used to be behind it in a storm. I took the rest of tree down. Now I need to order 1 new section of fence and a new mesh pool cover.

Funny story actually - my mom came over to watch the kids so the wife and I could go out to dinner. She said "hey, you better take care of that dead tree before it falls on your pool" I said, yeah, but it's cold, I'll get it in the spring. Later that night she sent me a pic via text.

I stopped and got some liquid CYA on the way home yesterday, the powder is taking too long. There must be gold in that bottle from the $$$! I measured the FC @ 5 when I got home from work, so that isn't good, but we did have a fairly sunny day. (FC was 14 in the morning, and I added 1 gal 10%).

Last night:
FC 15.5
CC 1.5
TA 140
CYA 25

This morning:
FC 14.5
CC 1.5
TA 240 (somethin ain't right, probably bad testing)

So I think that means I am nearing the end of the SLAM. I added another 1.5g of 10% this morning because I don't have a handle on the daily loss yet. Still a bit concerned that the CC isn't dropping. The water is still cloudy, but the visible particles are way down.

Yes, liquid CYA is expensive, the granular is quite a bit cheaper. Be sure to wipe the tip of the TA reagent on a wet towel to release static and hold the bottle fully vertical.

This morning's numbers:
FC 9.5
CC 1.5
TA 130
CYA 30
CH 150

Seems to be using more Cl that it has been yesterday and last night. Rain related? I put in 2.5g of 10%, which should bring the FC up to 20. Hopefully that is enough to make it through the day. I also took a CH expecting to find it high on the account of well water top-offs, but it doesn't look bad. I can see about 18 inches into the water now, starting to get excited! :eek:

Also - that CYA test is super subjective. I can change the ambient light and get any result I want...
