So would everyone agree that the general consensus seems to be I either build a custom sump to fit my needs or I pick up two FX5s and call it a day? If that is the case I will start pricing everything I would need to build a sump and compare that to say roughly $450 for two FX5s shipped. Either way, if I can keep the filtration system under $500 I'll be in good shape. The goal for my tank build was to keep the cost below $1000 and I'd hate to spend more than half of that on filtration... I'll see what I can find out about building a sump and go from there. In the meantime I appreciate any and all input on the situation. As much as I'd like to save money, I also want to make sure my tank stays clean and healthy. Oh and like I mentioned earlier, the less cleaning/maintenance I have to do the better. I definitely don't want to be spending a lot of money replacing filter media each month...
