ok so i finally found a dealer in colorado springs. he himself has a octo tank at home. but there were a few things he said that puzzeled me. firstly, my tank here is a 55 gallon with about 10 lbs. of live rock in it and some dead corals and rocks also there is 1 inch thick aragonite sand. it has been cycling for about one month and everything looks fine (ammonia, nitrate, and nitrite are at zero). i had the salinity at 1.028, but the dealer told me that since i'm at high altitude (about 8000 ft.) my salinity levels have to be around 1.020-1.021. that seems really low to me. he also keeps alot of water flowing in his tank with submersible powerheads. i don't remember reading much about water circulation in reference to octos. he also gets his octos from fiji and he isn't sure on the species, but he did call it a bali which i know isn't really that great. he said that it is a fairly smaller octo. max 18 inches from tenacle to tentalcle i think. can anyone help me with all this stuff? does anyone know what species he might be selling?
