I am planning to set up a ~120 gallon biotopic discus tank. This is what i was planning:

The Tank:

120 gallon (4x2x2) or similar size and shaped aquarium


The Sump:

55 Gallon (4x1x1.66), with water level around 4" above the display tank, with waterfall type overflow into display tank

The Water:

pH 7.2
6 degrees german hardness
^These values are out of tap. I plan to filter with peat, but am unsure of what the exact pH and hardness will be after peat filtration
Temperature of 82F

I plan to perform 40-50% water changes 2-3 times per week


The Fish:

10 Discus
12 Corydoras
6 Otocinclus - will remove if a problem w/ the discus occurs
4 Blue Rams
25 Tetras - would like neons, but am unsure if they can take higher temps. If not neons, then lemon tetras

Ghost shrimp - i plan to introduce them long before the fish, so that a population can be established, and then slowly picked off by the fish for food.


The Decorations:

Substrate - White Sand

Background - I plan on constructing one from styrofoam and then covering it with white sand and then some fish safe waterproofing product

Decorations - Driftwood: one large "stump" peice extending out of the water
Other Decor: Numeorus leaves and small sticks, which i plan to coat in a clear fish safe water proofing product to protect from rotting

The Plants - Aquatic: Water Lilies, Amazon Swords, Anacharis
Floating: Duckweed or Frogbit
Terrestrial: Numerous, on driftwood described above


The Equipment:

2x 300 watt submerged heaters in sump
Fluval FX5 for water flow through sump and extra filtration



Above is the setup as i have planned it thus far, what follows are the questions i have regarding the tank:

1. Are their any problems with the above plan?
2. Assuming i suspended the lighting around 1' above the tank from the ceiling, how much light would i need to grow the plants i mentioned above?
3. Can neons take temperatures of 82F?
4. Has anyone tried coating leaves and small sticks with some sort of clear water proofing for use in a display tank? Did it work? Any considerations?
5. What should be used to waterproof backgrounds, the sticks/leaves described above, etc, for use in a display tank?
6. Would placing the sump in direct sunlight cause problems? I was thinking that the light would promote algae growth, which in the sump would be a good thing, as it would help clean the water. Or am i wrong?


Sorry for the excessively long post. Thanks for reading, and thanks for helping me :) Also, if this is in the wrong forum, please move it.
 
A true Discus biotope will have no plants, just roots and stumps. So, I guess you want a planted Discus tank, not a biotope. For your lighting, around 2 watts per gal. is a basic guide for most plants. Neons will die off one by one in high temps. Clear, epoxy casting resin can be used to coat your stuff with. You can even pour this over a thin layer of sand, to create a bare bottom tank that doesn't look like one. No doubt, sunlight on your sump could cause algae to grow. Helpful, or harmful. Well, ugly for sure!
 
about biotope or planted - i plan for most of the plants to be terrestrial ones, on the driftwood. I have seen pictures of supposed discus biotopes with a few, sparse aquatic plants, which is what i wanted to replicate. ;)

Would 2 watts per gallon be sufficient even if the lights are suspended about a foot above the tank? Or would 3 be better?

About neons/tetras - besides cardinals, which tetras can take the heat? I plan on maintaining the tank at 82F, so i assume the range of compatible tetras is greater?

Also, thanks for the info on the clear resin - i will look into it :)

Finally, about the sump - in what ways could it be harmful? I know it wouldnt look good, but the sump would be hidden from view, so anesthetics arent important. I just wanted to know if it would be beneficial or not to the system.
 
instead of neon tetras, I would put cardinal and rummynose. Rummynoses lose the red on their noses with decline in water quality, so they are good monitors of when you need to take care. Cardinals look a lot better than neons
 
actually a tru biotope for discus has plants during the rainy season the discus spread out over the new flooded jungle and lay there eggs on the leaves of plants and trees. I agree add some plants to your tank, only one part of the year they don't have any, Call it a rainy season discus biotope.....LOL

pure genius! LOL!!!
 
LOL - good thinking - i knew i was right, somehow :P

as for cardinals instead of neons - i personally like neons better, and in my experience they tend to live longer. Also, the cardinals in my area do not look too strong. Rummynoses may be a good choice, but i would like something with a bit more color. How long can cardinals live, assuming they are healthy? Also, would a pH of 7.2 be okay? It may go lower with the peat, but if it doesnt, i want to make sure it would still work. Also, are their any tank bred cardinals available on the market?
 
you are right about longevity. Cardinals only last 2-3 years, and are more fragile, especially in pH's higher than 6. Still, it will look really nice
 
I was just looking at some tetra species, and was wondering if any of these would work in this setup, meaning they must be able to thrive at 82F, and be compatible with discus.
1. Bleeding Heart Tetra
2. Lemon Tetra
3. Emperor Tetra
4. Any pencilfish species?

Thanks :)

i have had almost every kind of tetra live in 80F tanks, another fish that would work besides corys is gouramis unless you want to keep it pretty much all amazon. and personally my favorite tetra is the congo, ( i work at **************** so have pretty much seen them all. this link might help a little...
