Ok so I am getting a 330 gallon tank sized 108 x 24 x 30 tall. I picked up a 225 gallon divided acrylic tank sized 96 x 18 x 24. Currently the sump tank is divided into 3 categories I plan to place a few more and divide it as such. Drains with a 200 micron sock heading into a aqua mesh coarse filter and then into some filter pad. It will lead under the divided and hit about 8 bags of SeaChem matrix and 4 bags of some fluval bio media I can not remember the name of. Going over the divider it will be in the middle and hit my 70 gallon section filled with 4 cubic feet of k1 mini with 5 air stones and a alita 60 air pump. It will then flow out and this section will most likely just be nothing unless someone can come up with something to add outside just a section for pumps heaters and maybe a carbon reactor. Maybe a big plant to help with nitrates if they seem to be out of control later. I will have the tank in my living room on a wall that is butt up against the garage and the sump will be located in that garage. Currently I have for a set up besides the sump items. 2 apex cor 20 pumps, an apex system, blue led strand for night lights, 2 Evo quad 6700k lights. 2 800 way heaters. There will be 2 1” returns and 2 1.5” drains. I have 2 tunze 6105 and 6095 powerhead. 1 in each side and the 6095 in the back to flow back there and maybe adding a second back there to help spread if need be. As far as plants I’d like to do some basic forgiving plants. I’d like to try and avoid co2 I think it will become a hassle to keep it accurate with so much water. So any recommendations on what you would suggest with what items I have currently would be nice. As far as stocking.... I’d like the most advice with this. I have a 120 gallon tank that had about 30 cichlids in it and I returned some to a fish store because they were just breeding like crazy. And about a month after that the 120 sprung a leak and before I could stop the water and clean up the mess I neglected the fish too long and lost a few and then I set the sump outside and I think the poor water conditions finished most of the rest off. So currently I have 1 mbuna and 2 Malawi peacocks. Ive obviously considered keeping maybe 30-50 cichlids in the tank but feel the fighting and a ton of the same fish may become boring to see. I’ve thought about a freshwater ray and keep it with some cichlids and Pleco or something until it gets to a bigger size, any thoughts or experiences with these guys? I’ve only ever seen them mostly as a pair separate. I’ve thought of doing a mild planted tank with a few cichlids maybe 10 and just a bunch of random things like snails, Plecos, gouramis, ottos, cats and such to give a more natural mixture of fish in such a large aquarium. Any thoughts and opinions would help up on what you would change or advice to be careful with.
