Not sure how it got so high. Never added cal-hypo shock. Ive tested the fill water a few times and its always been that low. The pool does lose what seems a fair bit of water to evaporation. It’s in the sun pretty much all day.

Fill water CH is about 50

Hello all, Been using the TFP method since I built my pool last year. Last week, I had to do a full drain and acid wash to deal with severe mottling with my pebble Fina. I refilled the pool a few days ago and began adding chemicals. Before I drained the pool, calcium hardness was over 1100...

Thank you so much for your help. I really appreciate it

How many horsepower with the above setup put me at?

Correct. I need to change my sig. and yes, the pump has its own dedicated filter, a Pentair 100sq ft clean and clear cartridge filter

And filter gauge is about 40” above the water level.

Pump is a Pentair 011530. 3hp. 3.45 sfhp Filter pressure with throttling 27psi. no throttling, everything open 15. 2 1/2” on suction side. Length to pool, is about 45’ single run for suction, 4 separate runs to the water features.

Hello all, Just built my pool a few months ago (owner build). I have a dedicated pump for my water features (one bubbler, one 36”sheer descent, and two Pentair laminars). Each is controlled by its own valve and powered by a 2 H.P. Pentair whisperflow pump. The problem I’m having is, I...

Awesome. Thank you

Will that help with the CSI aswell?

The Ph is purposely low and am aerating, to lower the TA. It was at 110 a few days ago

numbers are as follows: PH 7.2 TA 90 CH 475 CYA 80 Water temp 64* Salt 3900 BOR 50 According to the pool math app, these numbers are within target, close to ideal. CSI shows -.64 how can I raise CSI and get close to zero?

Ha ha. Sounds good. I’ll leave it be and let it settle.

How do you recommend I lower T/A?

Very grateful to have found this site. Thank you for your responses so far

Finish/fill date was 12-21, that’s when the equipment minus the SWG was kicked on. Salt was added and SWG started late January.

Recently finished my build last month. Since I know, pics will be requested.

Hey everyone, can you guys/gals please evaluate my results? Using a TF-100 test kit. Pool is located in Southern California (Inland Empire). Current temps are 70* high and 45* low. Pool temp is about 50*. Seems like I’m adding a lot of acid on an almost daily basis. Trying to get my...

What did you end up going with?

Seems like a cool idea, just not sure about the risks

Not a whole lot of information on them online and even less on this forum. What’s everyone’s thoughts on them?

I’m doing an OB. Definitely a learning experience.

Awesome. Thank you for your input.
