i was wondering how much flow i will need to get for my 150 gallon bare bottom tank. i plan on keeping everything up to sps. i was wondering what kind of powerheads and how many. i also saw at the lfs the guy t'd off his return pump so he had a bunch of nossels hiddin in the live rock that was also working like powerheads. has anyone elso done this? and also i still need to buy the protein skimmer. the one the tank came with isn't working. it was a berlin protien skimmer for a tank up to 250 gallons. is there anything i could do with that instead of throwing it away? please keep in mind with all these questions im asking im not rich...... but i do want quality thanks in advance.
