100g Low Tech MH / CF Lighting Help Needed
Hello - I've got a new 100gal (60x18x20) acrylic tank that I intend to set up with african cichlids and a few plant types as recommended (yes I know the two don't always mix well and have read about some of the workarounds on this board). It's been awhile since I've been at this hobby so I really need a recommendation as to what combination and types of lamps to use and the proper amount of wattage.
My goal is to provide the glimmer from MH while bringing out the color of the fish and providing enough light/range to help support some plant growth. Currently I'm looking at a 60" fixture that comes with (3) 250w MH and (4) CF which seems the norm for this size fixture. I suspect this might be overkill but the seller seems to be willing to exchange lamps, at least in different kelvin ranges (not sure if I can swap for 175w MH yet).
That said, would I be able to accomplish this with MH alone (175w or 250w?), or do I want a combination including CF? What is the proper Kelvin range for the MH and/or for the CF to achieve my goal?
Many thanks and throughly confused!,
