I just recently bought a new 90G DAS tank 36x18X31. I am planning to transper my 40g tank with lots of plants and 4 discus. The 90G tank has a overflow with 3 holes and I want to put a 30G sump. Things needed help with:
1. Lights... I saw a 36" 192watts PC light in ebay. It will have a little more than 2watts per gallon. Is This enough.
2. 30 gallon sump. Needed a pump that will circulate the tank more than 5 times of the water and will not heat the water to much.
3. I have a fluval 205 in my old tank and a magnum 350 that not using is this enough for biological media for my new tank? How can I inject that nitrifying bacteria in my new tank and how long will I have to run it?
4. 3 holes in the overflow whats the 3rd hole for. they told be for (close system)? I dont understand.
5. Can I put those 2 cannister filters as a return line of my water or just run it in the sump and put a pump.
6. Needed help in setting up a sump with 2 cannister filter.

Thank you very much for quick responce. I will be looking for Metal halide fixture coz my tank is tall. I will also look for that reeflo pump to see if fits my budget. Thank you.

I looked at that reeflo pump its not submersible. I saw one its called mag drive 12 it has twice the flow I need for my sump. Have anyone of you used this one? I saw the metal halide 250w on ebay but they only come in 14000k spectrum. I saw a 10000k spectrum bulb but I didnt saw a 6700k spectrum bulb for this one. Is 10000k spectrum ok for planted aquarium?

I saw this light it has 150w metal halide + 2 39w T5. Is this enough for a 90G tall tank.
