Frag tank

[toytech]

my 15 gal frag tank has no skimmer and i find my tank is a little too clean for my zoas and lps the start to bleach if i dont feed them regularily , i dont have much for sps but once i started feeding they did get better color too.

I'm gonna be doing mostly sps and maybe some chalice.
So who think reusing my old water will be.ok?

IMO water quality should be good in your fragtank since most are healing from being cut
