Good evening TFPers,
I am seeing evidence of algae appearing in my pool (if started from scratch with fresh water and chemicals added by the pool guys two or three weeks ago)
I have been waiting patiently for my test kit to arrive for several days...but unfortunately it has not arrived yet. Therefore I am going to have to guess how much shock to throw in...any suggestions (it's a 25000 gallon pool).
Once the kit arrives I can do the full battery of tests...but I don't want the pool turning into a swamp while I wait
