I purchased a pool with a house in the Tampa area 4 weeks ago.
I've been doing a good bit of searching to come prepared to the task at hand, which is maintain my pool with no professional intervention. Unfortunately I came across this forum a couple of weeks too late.
Previous owner has been using packs for a while I believe and I thought it would be ok to continue. Testing my water regularly I was pleased with my chlorine levels (always around 4-5ppm). (All the other chemistry in check). Unfortunately I realized late that a CYA of 100 is not cool, even in Florida So last week I got algae.
I might have Clorox written all over my pool now but following the suggestions on this forum I think I got the upper hand...
Thank you all for your help and professionalism
