Trichlor is ACIDIC and will lower the TA over time. For every 10 ppm FC added by Trichlor, it also increases CYA by 6 ppm and lowers TA by 7 ppm....

Thanks for the clarification Richard.

Did you use Muriatic acid (Hydrochloric Acid) to lower TA and aeration to increase PH
I have been using this for quiet a while with good results

Hello,

I would start off first by throwing away the test strips and purchasing a good test kit like the Taylor k2006. You need to adjust your...

The update you that you quoted at the end is the best way to control TA. Reduce TA to the correct level with MA and then aerate to bring the PH up (I...

Just wondering, have you solved your problem already?

Maintain your Cl >5.0: Use Household bleach or Sodium Hypochlorite.
Maintain pH 7.4-7.8: Lower pH with Muriatic Acid/Raise ph with Sodium...

Your pH target is set too low. It shouldn't be lower than 7.5 and for your pool it perhaps should be at 7.7 or 7.8 instead, especially if you have...

Buy some extra cartridge filters and change them daily until gone which means run the little pump/filter 24/7 or it goes no where.

I maintained my pool old school for over 30 years with great success after some initial trial and error in the 80's. 15 years ago I became severely...

Muriatic acid and liquid shock are two different things
Muriatic acid (hydrochloric acid) will lower TA and PH wheras liquid shock would be chlorine...

Be careful with it as it is pretty noxious
Wear some type of rubber/vinyl/latex gloves
Use in a well ventilated area
Don't breathe the fumes
Dilute...

Are you using test strips? If so, they are useless. Get yourself a proper test kit -- either the TFTestkits TF-100 or the Taylor K-2006 where the...

I agree wit Richard.
This time a year if your water gets cloudy and your alkalinity is not too high, shock the pool!
And give it a good dose!
I...

Update, finally got my K-2006 test kit. Here's where I stand:

FC - 0
pH - 7.3
TA - 170
CYA - 50
CH - 260

I'm thinking I simply need higher chlorine...
