well, i just started up my 58 rr and also have a 29bc (which fish are in). ok to the problem the 29 is cycled and everything is good para wise. i have also in the 29 blue hermits, cs,snails. i want to know if i can cycle the iverts with the 58. if not what should i do with them while the fish are being treated...going to try hypo for the first time. i ordered a refracto yesterday. the 58rr has 50# lr and 70# ls with ro water. also the 29 has sand should i take that out??? im only going to use the 29 tank to qt/treat fish.
