I could totally be getting caught up with the ratio of changed water to total tank volume (basically a 25% weekly water change) but with that stock list that seems a little small. If you're going this big why not do some sort of drip?The filteration will be a 7Lx3Wx1H glass sump with a jebao 6500 as a return pump, seeing as the fish will be within 5-6" I don't want a massive turn over just yet, but once they start putting on some weight that pump will be upgraded to 10000. I will be doing 2 weekly water changes 100 gallons per change so a total of 200 gallons
