I drained and refilled to get rid of high CYA and solve algae problems. I understand much more now thanks to the School and Forum
I need to add some CYA to protect my FC, and I have a whole bucket of Trichlor pucks. But I am scared that I will end up with low pH problems.
Is it EVER ok to trust Trichlor? should I use Dichlor (and add it slowly, test for CYA frequently) or buy plain CYA?
What do I do with a nearly full bucket of Trichlor pucks!
