I hope the sump don't leak too much CO2. I will reduce the surface agitation by making a full syphon with bean animal system. Do you have a sump? Can I start a low tech tank with this kind of filtration?Good call in ditching the canister for a sump.

I personally recommend just capping dirt with something cheap like black diamond blasting sand. I used to have dirt capped with eco complete and can say that BDBS is way better. Stuff is like $8 per 50lb bag. Just make sure you rinse the crap out of it.
What are you planning for fish? In a large tank like that a school of like 100 fish of the same species would be cool
I can do 2 inches of soil and 2 inches of sand, how deep my substrate can be? Can you do hills with this kind of substrate?I would say to make the substrate deeper. One inch of nutrient rich substrate is not very much if you were to have long rooted low light plants such as crypts etc. even if you reverse it to 1 inch sand 2 inches soil or 2 inches of each I think you might be better off.
Strongly recommend against this option. The angelfish will get large enough to eat the neons and rasboras, and they will.I still evaluating my fish option:
1.- Angel fish, tetras neon, axelrod rasboras, cory cats
The sump should be fine if you put a lid on it, i believe that's what Tom Barr did with his set upsI hope the sump don't leak too much CO2.

Thats why discus are my second option. I know angels can be aggresive but its a good option because of the height of the tank.>Strongly recommend against this option. The angelfish will get large enough to eat the neons and rasboras, and they will.
They might live together for months or years if the angelfish are very young when introduced to the tank, but eventually you'll find your neons and rasboras mysteriously disappearing.
Discus are stunning, but they are not low-maintenance fish.
Large schools of tetras, etc. would be amazing, but it would cost a lot for that many fish. Unless you breed them yourself. ;-)
I'm thinking doing hills with lava rock, maybe a big hill in the side of the tank of 15 inch. When I start the hardscape I will send some pictures.I'd go with making a row of rock where you want the slope to be. Rocks can have plants growing between them or could have moss/Anubias/ferns growing on them, they wouldn't be wasted space! And by row I meant more or less continuous barrier, not a straight row! I'd be sure to completely block possible movement of the soil with plastic strips a bit higher than the level of the soil. You don't much mind sand traveling down hill but soil traveling down might be a problem. If you want a good slope then fill the back of the tank with socks of gravel or lava rock, place the barrier row of more decorative rocks, put down a soil barrier then put on the dirt and the cap.
I haven't actually dirted a tank but less is more. The dirt is a more permanent fertilizer is all, not an actual substrate meant to hold plants safely. An inch of dirt is suggested in that really long thread about mineralizing soil.
Angelfish are fine with deep bodied tetras like diamond, bleeding heart, phantom, pristella, lemon but avoid the torpedo shaped ones like neons and cardinals. Agree about the corydoras, lots of fun to watch and they do breed in the tank. If there is enough cover you may have some babies surviving. Also consider the 'clean up crew'. Since they are busy they can be the most interesting tank occupants. Even large shrimp could have trouble surviving angelfish but platies/swordtails and bristlenose plecos are fine.
As for equipment, sumps are great as you already know and if you can do a beananimal I am envious, I only have a Herbie. It is the drop in the overflow and the bubbling from the drain that degas CO2 the most. With the BA the bubbling is not an issue and easy enough to keep the tank/overflow levels close enough that there isn't much of a drop. The tank shouldn't lose any more CO2 than any other tank with a similar surface area. I only have a 200 watt heater in the tank and so far so good, have another in reserve in case. The lighting will be pretty low light.
