Hey guys with the petco sale going on I bought a 40b and 20g long for sump and was looking for some equipment advice. Plan to be a frag tank with a pair of clowns. So far the plan is Tank- 40g breeder and 20g long sump Stand - just built with 2x4 Lighting - 2 AI primes Overflow - 16" shadow overflow (This might be overkill maybe? Was looking for something really quiet.) Bio media- Maybe marine pure blocks in sump? Not sure how big of blocks to get. Or just use some dry rocks? If so how many pounds? Return pump - sicce 2.0? Not really sure on this either. Skimmer - was thinking vertex omega 130 but its sold out on brs and not sure what is really neccessary and what brands are good. Powerheads - Not too sure on this either was back and forth between just some hydor power heads or looking to get a dc powerhead. Didnt really want to shell out a ton but may have to? Anything else I could be missing? Advice is very welcome. Thanks!
