Fiberglass PH isues

[waterbear]

fiberglass is pretty non reactive with just about anything in the pool except metals! It should have no impact on your pH. I will bet that your are chlorinating with trichlor pucks which have a very low pH. BTW, Soda ash IS pH increaser IS Washing Soda from the grocery store!

What is your Total alkalinity? I suspect it is very low. If it is below about 100 ppm use baking soda (good old Arm and Hammer) to raise it first then ajust your pH if needed.
It would really be helpful if you could post a full set of tests results so we can get a handle on what is going on in your pool and help you with dosing ,etc. and

Hey thanks for the reply and advie etc.


The only testing I've done ATM is your typical Chlor/PH test. It's always around 2.0 chlor and 6.8 PH. The next time I'm out there I'll pull a sample and test it at the shop.
