K-1 question

[rako1]

I have a 14 gal cube that I run K1 in and it has built up some algi on it and sunk do I pull it and clean it or replace it if so do I do a little at a time or all at once. I do run a skimmer and my paramiters always seem good

Pull it off, clean it in some vinegar and water, that'll do ya.
