Passed the OCLT and yes the FC is holding like a rock now. CC = 0.

I started the SLAM last weekend, cleaned the filter, removed all debris from the pool. Throughout the week, I was losing around 3.5 ppm of FC every few hours. I brought my FC a few ppm over SLAM level to account for this and maintain the above. I have been adding around 1-2 gallons of 10%...

Completed the 50% drain/fill over the weekend. Now measuring at: CYA = 40 ppm CH = 400 ppm PH = 7.5 ppm TA = 100 ppm I will put in some muriatic acid to get my PH to 7.2 and aerate by running my waterfalls then start the SLAM process. Looks like I am making progress now...

Update: Added bleach yesterday until my FC = 9 ppm (CC= 1 ppm) after an hour running the pump on high Took readings after the sun went down at 7 PM and FC = 7.5 ppm and CC = 1.0 ppm >>> Took again at 5 am and FC = 4 ppm and CC = 1.5 ppm Also got the CH test down better letting the drops form...

I think something might be wrong with my CH (R-0012) dropper, the drops are much much smaller than any of my other bottles and I tested my tap water with it and it’s 500 ppm, doesn’t seem right.

Mark, I really appreciate the help. I am a PETE from LSU, working for SLB now, was interesting to see that you worked in the industry too. I didn't get a speed stir only because I was worried it said it was back-ordered and didn't want to delay getting the test kit but I do plan on getting...

HI, TF-100 test kit arrived this morning. FC = 0.5 ppm CC = 0.5 ppm CH = 1,825 ppm (takes me >70 drops to get a color change...) TA = 70 ppm CYA = 80 or 90 ppm (Kind of objective and not sure if my eyesight is the best) Also yellow algae getting worse, feeling like the old owners left me...

So it looks like my pump is a Hayward TriStar SPX3210X15Z2PE and my power end is a SPX3215Z2BER. I am assuming this mismatch because the motor was replaced around 2018 indicated by the serial #. As the pump I think is original to the pool from 2010, again just going off the manufacture date...

Yes, agreed. Hopefully, the test kit arrives in a few days and I'll update with those readings.

Thanks for your reply. I'm ordering the TF-100, although if confirmed it seems like I have to get my CYA lower, so I mine as well deal with the CH as well. What is the best way to have some of the pool water drained/refilled? It seems like this is the only option I have to get the pool back in...

Just moved into a house with a pool and trying to get to the starting line, Any advice? - pool info in sig. I have some little yellow algae forming I believe from the pool being neglected between changing owners. 12/5 Accublue at Leslie's Pool Store FC – 1.06 ppm CC – 3.1 ppm! pH - 7.7 TA –...
