I'm finally at the stage where I can start to properly plan and get bits for my new 280 litre, and I have a few questions.
Maximum sand depth?
If the minimum sand depth is around one inch, is there a maximum? I am thinking of doing a cool aquascape with areas of deeper substrate and greater height, but I've heard something about toxic gas build up or bacteria? I know very little about this, and I don't know which internet sources to trust other than you people here at TFF. I've put in two pictures I've found online that I like how the substrate is arranged, in terms of placement and depth variation. I've seen people say to keep sand depth under 3", but I don't understand why. Won't plants like amazon swords need substrate depth for root growth?
I know the sand will settle a bit, but I want to achieve height layers without obvious walls of rocks and stones. I don't know how else I could add substrate height in areas.
Corydoras and sand surface area
I know that sand is important for corys instead of gravel substrate, but how much room do they need? I want to have lots of beautiful hardscape and plants, and I don't want to leave the corys without enough sand to do cory activities. The tank is roughly 120cm long and 40cm wide (60 cm tall.) Would about 1/3 be too little of open sand area?
Corydoras and carpeting plants
So far from what I've read online, it seems like carpet plants get disturbed and destroyed by some cory species. Would an area of established carpeting plants be an option with corys? Ideally there would be areas within the tank that are heavily planted, some areas sparsely planted and an area with no plants at all.
Corydoras and root tabs
For any root feeding plants, I'll want to have root tabs in the sand. How deep would they need to be in the substrate so that corys won't move them? Maybe I've over estimated their digging and sand moving capabilities.
Thanks for looking at my questions so far, any advice would be appreciated!
