Would 2 of these HO T5's 48" be enough for a 90G tank 48"x18"x24"h that will have South American cichlids mostly with some Java Ferns & Java Moss etc nothing fancy as far as plants go. I don't want so much light I get algae problems but enough to grow some basic plants without getting into a CO2 setup. I'm looking at the Coralife dual setup and I would just remove the actinic bulb and get something else and it looks like from the pictures of their website you can turn each bulb on separately which would be nice but I don't know if it can be suspended from the canopy I'm going to build. Hagen makes a setup that is just the reflector and ballast setup that's reasonably priced but i don't think you can turn the bulbs off/on independently. Which of these setups are you guys using??

Yes, more than enough. You may only need one. You may find two is too much, and the plants that you're keeping don't require a lot of light.

Here's a link to Coralife's website then a little ways down the page just click on the tab that says "T5 H.O. DUAL". http://coralifeproducts.com/product/hoo ... -fixtures/

This is the Current Nova Extreme one which also looks pretty nice and they have a freshwater version so I wouldn't have to get new bulbs but it looks like there is only one power switch for both bulbs and the legs look cheesy and flimsy. It also has a built in space to add their true lumen led setup to the fixture down the road if you want to which is kinda cool. O and I don't know how I could hang it from my canopy same as the Coralife. http://www.current-usa.com/lighting/nova-extreme-2x

Here are links to Hagen's retrofit kit https://www.fosterandsmithaquatics.com/ ... atid=19811

And here is their actual fixture setup that comes with the ability to hang or tank mount and they have a single or dual bulb setup https://www.fosterandsmithaquatics.com/ ... atid=19759

There is only one power switch for both lamps for the Coralife HO Dual. You would need to get the Coralife Lunar to turn the lamps on independently. This is however a 4 lamp not two lamp fixture.

Thank you for clearing this up and this helped make up my mind. I'm just going to get the reflector and ballast setup separate and attach it to the top of the canopy I'm going to build for the tank. If I get the ballast that is for two bulbs can I just leave one bulb out if 2 are to much or will that make the other bulb not work properly??

It depends on the type of ballast used. With most electronic ballasts it will not work if one lamp is removed. For HO T5 that is the only type of ballast you will find.
