Good luck, what are you gonna try to grow?
Bump: also some of the plants you are suggesting dont need co2...of course co2 helps all plants but some of the plants are slow growing and are prone to getting covered with algae issuesGuys... Here is my plant list, If you see any issues please speak up, and if you see any compatability issues between discus temp of around 84 for 2-3" discus and these plants... Please let me know!!!
Plant list is shown below:
- patches of HC
- patches of crypt parva
- crypt wendtii green gecko
- crypt walkerie legro
- blyx japonica
- pygmy chain or plain chain sword at base of some driftwoods
The tank's entire weight is under the hold of the screws. Rimmed tanks weight sits on the edges. That weight transfers down into your rectangular shape directly under the tank. This weight is transferred to your vertical 2x4's through the screws. It will probably be fine, but I've seen a lot of screws break. Why not just add a couple 2x4's and know if will be structurally sound?As far as structural issues with the stand, I apporeciate you looking it over, however the loadbearing part of the stand is the 4 2x4 columns which sit directly under the tank's plywood sheet and go directly to the ground. the screws hold it together but are not under stress. I've had the tank running for a few years in multiple locations so it will be OK. Planning to soak the driftwood this evening.
Regardless of co2, planted tanks make terrible grow out tanks for discus. They're fine for adults, but not young ones. With young discus, it is imperative that the water be beyond pristine - which with young fish that require a lot of food to grow properly means large daily water changes. Bare bottom tanks are typically recommended for growing discus because it's just not possible to clean the substrate (that's obviously required for planted tanks) to the degree that growing discus need. They can move to tanks with substrate once they're a bit older, but it's not a good plan with juveniles.
I've been reading in depth on other discus specific forums and this 40 would be a growout for 5-6 of them. I'm still deciding though because of the co2 injection the DIscus will not like the Ph swings between day and night.
