Hey cowfishrule, Yes I thought that also but the lfs said it would be ok since my tank had been reading 0 on everything for about two weeks now. I bought about 100+ pound of lr that came out of a 3 yo tank and the tank cycled fast. Readings ran up the first week the zeroed out. Douche Bag seems to be doing great plus the lr I bought has a lot of aiptasia on it so he has plenty to work on. Thanks for the concern, theres nothing wrong with a little corrective criticism its just part of the learning process:happy:
