Arrow Please Explain Bulbs..

Hey guys and girls,

So I recently got a Odyssea Quad T5HO w/ Timer Fixture for my 55g FW Planted tank. It came with 2 x 54w 10k Bulbs, 2 x 54w Actenic Bulbs and 4 Blue Moon LEDs. I know this is too much light for my tank. I know that 10k is too much for my plants and that I should replace two-four bulbs with lower Kelvin rating. But I want to know is for the time being, are the 10k bulbs doing anything at all for my plants? Will they still grow? I plan to replace them, I just need to save more money. What bulbs would you suggest for a 55g heavily planted tank? Thanks for any advice, you guys are the best!

10k bulbs will be just fine, the Actinic bulbs are the ones that you are going to want to replace. They are made for growing corals in a reef tank. I believe that the Actinic will still grow plants, but they don't have the best aesthetics for a planted tank.

This is what Actinic/10k looks like in a planted tank.. Now these are LED's and the actinic to 10k ratio is 2/1 so it is bluer than a 1/1 actinic/10k but it gives you an idea.. would grow anything green just fine..



This is 3500k for a comparison:


this is actinic/10k/and 3500k mixed

Wow, okay. Thanks for the info and pictures!! So my plants are still getting plenty of light and I don't need to rush out and buy new bubls! Maybe i'll get pressurized co2 or a canister filter before I buy new bulbs then. Thanks.

the range i would steer towards is 6500k.

i use a qual t5ho over a 40 gallon breeder and recently upgraded the lamps to wave point bulbs. i am mixing tropical wave and red wave per their recommendation for planted tanks.

They just released the ultra growth wave which i would have gotten had i known but the tropical and red wave combination is great together for a planted tank.

Actinics really don't do anything for corals. They are for aesthetics only. They don't put out any PAR to speak of as far as I know.
