I am considering a planted tank with discus and rams as the primary fish. As part of the planning process I am figuring out if what I have is doable.
90g drilled tank with integral overflow.
40g long sump
Eheim canister filter
4x54w T5 lighting with LED night lights( I was planning a SW tank)
Two actinic blue bulbs, two 10k bulbs
5 gallons of aquariumplants.com natural substrate(previous project I didnt start)
Substrate: What I was thinking was pick up a bag of small grain gravel of a suitibly emo dark color and mix the two together thoroughly for the substrate. For a 90, would that be enough or should I get another bag of gravel?
Lighting: Are four bulbs too much? I can always not run one and they are on two circuits. I want one of the actinics, I am pretty sure unless I was doing a tank based on a freshwater spring, that they are useless but I want to bring out the blues in the rams and discus. Put 6500k bulbs in the other three slots or reduce them down to 2 bulbs? I havent decided on what plants yet just heavily planted.
Flow: I have a mag drive 7.5 for the return flow to the tank. I can aim it at the glass but at the height it is at I imagine the flow will be less than that. I also have a device that would allow for alternating current and could put an outflow at either end of the tank and it would go back and forth every ten seconds or so but a very minor back and forth(its not a wavemaker) also cuts water flow down a bit.
Sump: I was going to compartmentalize the really long sump to where the overflow goes into the first compartment, there is a large middle compartment where I put the heater, and the end compartment where the magdrive sits. I figure gunk and garbage should end up in the first two spaces for easy removal.
I was going to use the Eheim simply for mechanical filtration. Where would be a good place for this? I can put it in the sump to reduce current in the main tank or I can put it up there.
Think that about covers design questions so far.
