Sump for 400-500 gallon tank.

Look for a used 125, 150 or 180 and make your own. Glass is cheap and so is silicone. With a large tank, this is a good way to go... all you need is a tape measure, a few trips to the glass store, glass hole saw and some bulkheads if you want an external pump.

I tried this before and failed so miserably. Plus I want it to look good lol. I'm really looking at the bashsea ss60 and the fijicube the other guys mentioned, those look nice.

It's definitely bigger which would help, why do you say it's nicer though? I don't have much to compare performance of them which is the most important part. I think aesthetically the fijicube looks nicer and bashsea looks incredible but I wish the bashsea had lids for saltcreep like the fijicube does, at least I haven't seen anywhere on their site that it does.
