Just filled the pool and CH registered 200, the water never really heats up more than 86-88 degrees in the summer months, 88 after a long hot spell.

Passed OCLT! This mornings readings are, FC=12 CC=0 PH=7.5 TA=110 CH=200 CYA=20-30 (2 different tests!) CSI=0 Im gonna wait for FC to drop to7, drop PH to 7.0-7.2 and aerate (may have to repeat to get TA down to 90). Calcium Chloride to get CH to 250? Does it come in liquid? I have never...

I ran 2 different CYA tests using the TF100 and Pentair Rainbow CYA Turbidity test, and i got 2 different results. TF100= -20 still can see the black dot Pentair= almost 30 Which one is correct?

Ran OCLT last night and lost 1.5ppm of FC. This mornings readings: FC=12 CC=0.5 PH=7.5 TA=110 CH=200 CYA=20 black dot just about disappears CSI=0

I did an OCLT last night just to see and lost 3.5ppm of FC, gonna do one again tonight. I got my PH down to 7.5 but TA did not budge, still at 120. Pooldv, 60-80 on the TA? 90-120 is what is recommended i thought. Although, it says 70-90+ above my (now/target) in Poolmath.

Thanks Pooldv! according to poolmath if i lower PH to 7.5, TA 110, and CYA 30 it would put my CSI at -0.1, Sound about right to you?

So i started filling the pool on friday around noon and dissolving CYA granules (75oz.), it was almost full by 10p.m. that night. Yesterday i finished putting the filter back together, did some plumbing, and installed the IQ20-RS board, continued filling, chlorinated, started the system, added...

I need one of those 2speeds or VS's, but that is a whole other topic. Thanks!

Thanks Pooldv! Do i have to run the pump 24/7 during the SLAM?

ping - According to Poolmath i need 75 oz. of CYA granules to get to 20. When I am done with SLAM should i bump it to 30? Im gonna fill an old sock with the CYA and hose clamp the hose in the sock as the pool fills. I am open to suggestions. I appreciate all of your guys feedback! - - - Updated...

YippeeSkippy- I have the TFP test kit. Did i have to much copper and iron in my water. Should i have 0?

Hello, finally got the no drain acid bath done and I am draining as I am typing. i definitely had an algae problem before i did some repairs to the spa and did the acid bath. I just need some advice on getting chlorine and CYA immediately in the water. Should i start dissolving some CYA as it is...

The scale is definitely not as bad as it was in 2009, the walls, tile line are scale free but the steps, spa steps and benches, and floor have some build up and thicker patches here and there. The local pool place says that CH out of the tap here is 400-500, and I have to add water often due to...

One other problem that just sprung up is or was a bad algae bloom. My wife had a some friends and kids over and had the spa running and heated. She turned off spa mode but not the heater, and proceeded to heat the pool for 3 days right as we were getting a heat wave on top of it all. I never saw...

Thanks for the reply pooldv! So is it safe to leave the acid in the pool and spa for 3 days with repeated scrubbing? Is the aggressive water you are referring to safe to swim in?
