So rather than building a wet/dry right away for my new 75 gallon, I was thinking about getting a canister in the interim. Every canister seems like it is way overrated though. The fluval 405 says that it can handle a 100 gallon tank, but only puts out 340gph(not 500+). Rena tells me that the xp2 is big enough for my tank with only 300gph. Shouldn't I be looking at something with at least 375gph? So for a 75 gallon, I need to be looking at an fx5? Or is there something about canisters that allow you to use less water flow? Also has anyone had experience with jebo canisters? The 829 sells brand new on ebay for about $100 with 5 tiers for media and rated flow of 396 gph, I will probably end up going with this unless there are overall bad vibes with this company.
