The link that Mike provided is a must read IMO
. The filtration in SW
is completely different than in FW
. The HOBs have a very limited application in SW
and none at all in a tank your size. The live rock is your primary filtration. The best advice I can give you is to read, read, read. A SW
tank takes much more time to stabilize and establish. The equipment tends to be pricey, but you want to only have to buy it once. Are you interested in a reef setup or fish only? If you're within 6 months of moving, I'd suggest waiting and researching until you can go with the tank you want ultimately. My reef tank is 6 months old and only now something to show off (still has some issues). It takes a long time to cycle properly and let the natural algae blooms and other issues come and go. I sat with an UGLY tank for a couple months.
