Anyone use 65 watts light on a 29 gallon tank?


I currently use Coralife T-5 30" lights (2*18 watts) on my 29 gallon tank (30"L x 12"D x 18" H). The amount of lights seem to be fine with my plants and tank. The only problems I have is a very slow case of of brush algae, but it's easily controllable via bleach dipping plants. I'm thinking of going to 65 watt lights, since they have built in LEDs. I'm just concerned if that may be too much light for a low tech tank. I do not dose any ferts.

Has anyone been successful of going with this much light on a 29 gallon low tech tank?

I had the exact same setup 2 years ago.
if you want to stay with low tech plants,
your 2x18 will be fine, just keep the time
the lights are on to under 8 hours per day
to help delay those algae episodes.

you can find a separate cheap moonlight
without having to upgrade to a 65w fixture.

once you get to 65w-130w of light, you
will need to Fertilize & DIY Co2 to help
your plants out compete algae for any
available water borne nutrients.

so you might want to leave well enough alone.

I just replaced my 1x20w with a 2x30w DIY hood on my 29g flat back hex. The new hood is way too bright, I like how the 36" tube lights up the corners where the 24" tube wouldn't, but it's too bright, far too bright unless I add CO2. I'll either put the lights on a <4 hr timer, or take out one of the bulbs. I can guess it's going to grow algea as is unless I do.

Use some eggcrate over the top of your tank. It'll cut down on the light some.

I bought a Corallife 30 65W for my 29 gal "high tech" tank but now am starting wish I never did. I yearn for the old low tech days and I am wondering if there is anyway to put a lower wattage bulb in the fixture?

I did a 65W retrofit about 2 years ago, on my Eclipse-3 hood. Strange as it may sound, I think the plants were happier under the original 40W, and nuisance algae was a non-issue.

Ok, I guess I'll stick with the lights I have now. It's just, I want to use led moonlights. I don't want to use the suction type to stick on the glass, because it looks tacky. Plus I don't think it will look right, since it will be shining from the side at an angle, instead of straight down. Besides, I know suction cups don't last too long and I would probably just get frustrated trying to make the suction cups stick.

Coralife Aqua lights have a special base that can fit in tracks of their Coralife lights, but these look to be designed for the CF lights. My T5 light strip doesn't have tracks for the light to connect to.

I use Current USA Lunar lights, but need to be placed on top of a glass canopy or mounted on something. My 29 gallon tank is an open top tank and I want to stray away from using a glass top. I may just use a partial glass top, just to lay the lunar lights on.

Ive got a 29 gallon, and bought the coralife 1x65watt only to regret not getting the 2x65watt. I think the 2x65 would be much better. I know I have >2wpgs roughly, but smaller tanks I have read do better with a higher wpg whereas a 55gallon for example might do better with 2wpg or so. Just my experience/reading,,,

I have DIY c02 and cant keep enough c02 in there...

I have a 130W Coralife over my 29 gallon tank and I love it.

To answer the question, the ballast drives the bulbs so if you put a 55W bulb in the fixture it is still going to run at 65W.
