Ehh.. Don't want to hijack the thread but long story short, ended up nuking my tank with copper, took everything out my refugium into a 10 gallon, no tumble no growth and now I want to try coral. Stupid buddy of mine hooked me up with a 25 gallon nano and when I get the refugium going for that I'll get the tumble and I'm sure the growth. Till then it's blah lol
