I just got back my tax return, allthough small, I wanted to know what you guys would suggest to me lighting wise for my 46g tank? I want to be able to keep low-moderate light plants int he tank which should help cut down the cost. Any ideas for lights that I wont need a top cover for?

Wondering if something like this would be good for my plants?

i have been looking into something similar for my 29 that i want to plant for my office. Problem is that i can't tell what those LED models are equivalent to in terms of Flour of CF lights. im just getting into plants(this 29 will be my first foray) so maybe one of the flora-geeks will be able to answer your question.

Those lights that you posted are just all purpose lights and not really suitable for growing much in the line of plants. If you consider that the average output of a standard T12 6500K fluorescent bulb is 3200 lumens. That should give you a bit of a reference for that fixture.

Which one are you planning on getting?

The 36inch freshwater setup. It's in my price range, and would has a range of 78w with 10,000°K.
Which is only a few watts shy of being half the tank in wattage. Should be fine for my plants as they are low light. I'll be upgradign the bulbs later on two planet spectums as well.

If your plants are low light then that fixture is way more than enough for your plants.

Still, we're not talking about normal output lights here. Those are high output lights and put out way more than enough for your plants. IMO you would be better off looking for something just a little less powerful unless you want to get a bit more high tech with your setup.

What do you mean by more high tech with my setup?

I mean that with higher lighting your plants are going to start photosynthesizing faster, and thus will have a greater need for nutrients so you may very well have to start dosing ferts. The biggest thing however is that they will be using CO2 faster and thus they will need a carbon source, when you have an insufficient carbon source is when you have algae problems. You have too keep things in balance, as you increase in the amount of light you throw at your plants, you must also increase the CO2 (carbon source) and available nutrients. Here, read this article
http://www.aquaticcommunity.com/plants/balanced.php

I used the term CO2 in that article simply because if you want to see optimal plant growth, that is the best carbon source for them, but you can also use Flourish Excel, you just won't see the same growth rate as you do with CO2.

I use excel for addeding carbon.

I was checking out this very same line of lights (Nova Extreme SLR T-5) at Fosters & Smith for a 29 and a 55 gallon and I was completely sold on the output for the price, it seems like the best value hands down .
But then I read the 'testimonials' for those fixtures and a few different people say the fan is unacceptably loud :scry: Now I'm undecided on what to get again, everything else is a noticeable step up in price, some of it is much bulkier, and many of them don't have any feedback so their fans might be just as loud .
I'm wondering if it would be possible to retrofit the fans that come installed in the lights with some extra-quiet fans made for a PC ?

Does anyone have any experience with these fixtures or a recommendation for a better one ? :sconfused:
