What am i doing!?


I ordered some 32 watt led fixtures, for a low light setup from sunshine-systems, turns out they dont have them anymore. So, now they have shipped me out a couple of these AquaUFO+Red
The tank I am starting up for this is going to be my main show tank and I will be moving all of my rainbows over to it. It is a 125 gallon marineland 72Lx18Dx22H. I am planning on now heavily planting. Will these lights force me to use CO2 so I don't have an Algae mess?

according to their website, at 16"(ish) depth you would be looking at 110 micro mols

if you look at http://www.plantedtank.net/forums/sh...d.php?t=184368

you will see that over 50 micromols would be considered "high" light.

im sure someone else will chime in, but it seems to me that, yes, algae will be a problem without co2.

Raise the lights far above the tank and its not a problem. At 30 inches they are rated for ~50umols (so high light at your substrate if the lights are 8 inches off the top of the tank) and just 30umols at 40 inches.
