Default 25g tank: 2x36w vs 1x55w lights (or something else?)

I have a 25g high tank and am trying to choose between ahsupply's 2x36w and 1x55w kit. I think that the wattage from the 2x36w kit would be better for my tank. But I'm worried that since my tank is 24" long and the lights are 17.5" long that there will be dark areas in the corners of my tank. With the 1x55w kit, I'm worried that there will be too much shadowing in the lower parts of my stem plants.

A 2x55w kit would provide too much light for me, tho! Yes, I'll be using pressurized CO2, but would still like to keep my lighting at or below 3 WPG. (I have a baby coming and need to keep maintainance simple!) Is there a way to underdrive the 55w bulbs? What would that do to bulb lifespan?

Any other ideas? I've thought about having several normal output fluorescent bulbs. I like that PCs are more efficient than NOs, but I don't know how much this would really impact my electric bill and/or tank. Is it true that you can use PC bulbs until they burn out (with some reduction in output)?

Thanks for the help folks!

Welcome to APC!

Go with 2X36 watts. You can get more coverage front to back. Just make sure you keep up with the system.

1X55 watt will be good too, but not as explosive as the 2x36 watts. You'll be able to grow basically everything too, but at a slower rate. Maybe that's what you want with a new baby on the way.

PC bulbs last a long time. Some people switch them every year b/c they lose spectrum power. But it's really no big deal, use them till they burn out.

Thanks for the advice! I really like the lush tanks that I see with the higher light setups, but I need to be realistic about how much time I'll have to keep it up. I'll have to mull this one over a bit more. I guess I could always go with the 1x55 and add more light later -- that'd be more expensive tho.

If I went with the 2x36, how much more maintainance would you estimate this much more light to be? If I went with the 1x55, would I really be able to slack much on ferts, water changes, etc, anyway?

Thanks again!

2x36 watts you'll be pruning a little more weekly,
1x55 watt you'll be pruning biweekly

It both cases you'll still need to keep up on ferts co2, and waterchanges. You can slack off a bit more with 1x55.

I like the idea of the 2x36 due to the coverage it can provide. But 1x55 watt is probably enough to get the lush growth you desire as well.

If you're really not sure, you can always purchase 2x55watt kit and run one 55w bulb, and if you decided you want more light purchase one or two 36 watt bulbs for your 55 watt kit.

Maybe someone with a 25 gallon can chime in with their experience running 1x55. Again, I think you can grow pretty much everything with this too, but the coverage won't be as great as staggered 36s.

Thanks again! I think I'll go with a 2x55 so that I can try it both ways (1x55 for now and then go to 2x36 when the kiddo is 6+ months old).

I have a 25 gallon with a 1x55w and the corners of the tank get little light. If I were you I would go for 2x36w. The 55w is just not long enough.

Just to follow up: I'm very happy with a 1x55. I've planted easy, medium-light or less plants and am getting really great growth. I don't notice any dark corners in my tank.

Still, I'm glad that I bought the 2x55 kit so I can try 2x36 someday....

Awesome to hear mama_kk! I was wondering what you decided on. How'd you end up mounting the kit? Enclosure, retrofit?
