Finnex Planted 24/7

[gmh]

Does anyone have one of these? I bought the 36 inch version and have it over my 36 inch long, 17 inch deep 40 gallon tank.
My understanding is this unit can support low to mid light plants but not high light plants.
The most challenging plants I have right now are Ludgwigia Repons and Diandra. I'd like to get a carpet plant but not sure what this fixture can handle.
I have CO2 injection..

I have the 24" version of this. I've heard it can support high level plants. Alas, i don't have high light plants currently.

i have the light too,

no supporting evidence, but i would only expect high light on a 12" high (or shorter) aquarium.

it is the distance of the light from the plant that will define high light, not the volume of the aquarium.

I can't seem to find the article I read, but what doug said is the general idea. If I recall from my reading at 18" the PAR levels were about medium. There are some plants that will carpet under medium light with CO2 if you look around. I dont think something like DHG would work, but perhaps something like dwarf baby tears, s. repens or something like that. oop, I just found it, 60-65 PAR at 16" which is likely where you are after substrate. That's on the high side of medium.
