Is it normal to have a delayed result from a test for pH? I tested the pH after all this and initially it seems to read below 6.8. I left the sample in the vile, returning to it about 30 minutes later. The color in the vile had changed to a slight pink from the pale yellow it was earlier. The...

make sure there is good drainage. once you dig the hole, get it installed and back filled, the hole will be susceptible to flooding. I mean in heavy rain, the soft back fill dirt will absorb water much quicker than the surrounding dirt, creating pool around your pool which will make your liner...

Thanks, every one for your help. I've been doing some reading on the site. I would have never guessed that there was that much to it. Good news. The dark green had gone away! I'm continuing the soda ash treatment and airating. I'm going to do some water replacement once I get a good test kit...

I have soda ash. I thought it was the same

So trichlor pucks plunged the pH. After years of using it, I test the pH. I see it's low and try to balance it with soda ash aka sodium bicarbonate. The soda ash reacts with the copper in the water from my heat exchanger(dissolved by the low pH or high acidicy of the water?) Turning it Army green.

OK. I can do that. One question still remains. How did the pH drop that low? I need to know to prevent it in the future. And btw, I really appreciate all of yalls help.

The pool store wants me to follow up with them in the next day or so. I'll make sure they run the test for metal.So if it is metal, what's next? Do I drain the pool? Do I continue the soda ash treatment and if so will the green color fade to clear again?

And what is bromine btw? I don't see it in the chemistry ABCs

Tricloro tablets in a floater. And I looked at the paper is TAC that's at 8 (total available chlorine). My own test of chlorine and bromine reads at 3 for chlorine and 4.4 for bromine

Now I've noticed a few bits of PVC cement from the pipes floating around. It's not a lot, jus a few flakes. Also there seems to be a thin layer of an oily substance and there's Bubbles that persist on the surface like someone is spitting in it. Idk, maybe I should just drain it and start over...

Again and I can't stress enough, I know the pool store is inaccurate. For more that's all I have to go on until I get a better test kit. That being said, are there any problems with the numbers from above? The report that they printed out for me states that my CH and CYA are high and my TA and...

I ran some water from my faucet into a glass. I added some soda ash and the water didn't turn green. The pH checked out at 7.6 (before I added soda ash) so the question is, why had the pH in the pool dropped so drastically? Could the copper and cast iron components of my pool heater be the...

No, I understand what the tf100 Is. I just don't know all of ours capabilities or what it tests. I was asking if it tested for metals. And I know the pool store doesn't use the tf100 they have their own proprietary testing stuff. I'm not sure if they actually tested my water for metal . that...

I have used some algicide before. Only a handful of times. I'm on city water. - - - Updated - - - Does the tf100 year for metal? Idk if they actually ran the test

FC 8 CC 8 CYA 130 pH 7.0 TA 70 CH 600 Also: Base 20 Iron 0 Copper 0 Total dissolved solids 600 Phosphates 100 I had to go back to the pool store they didn't carry the test kit you mentioned so this data is from the pool store. Yes I know it can be inaccurate but that's all I've got for now...

This is not algae. This is a reaction that happened almost instantly (within minutes) of adding soda ash. My pool was sparkling clear before I did this.

So, I've had this pool for a couple years now and never had much issue with the water. I've never tested my chemistry of my water before, until the other day I got a free test kit. I thought it would be interesting to experiment with. It tests FC, pH, and bromine. The initial test revealed I...
