I was just wondering if i might be able to get advice and teachings from you folks at this forum. I have a 29 gallon oceanic biocube with about 29 or more pounds of liverock. Four inch sandbed maxi-jet 600 powerhead for extra flow. UV light and protein skimmer. Pretty much all the extras you can buy for it. I added BIO-spira to it yesterday because most of the liverock i did have was from another tank that had almost complete die off. I have 13 scarlet crabs in there now. Guy at local fish shop told me it would help establish the tank quicker along with the BIO-spira. I did unplug the UV sterilizer and protein skimmer when i added the BIO-spira as it does contain bacteria. I also have some addatives but would like some advice on what i actually do need and what i got sold . I have done what feels like alot of research, but would love to have some more advice from you folks. I would very much appreciate it. Thank you
