You will need to continue to use the Flourish comprehensive to provide the micro nutrients your plants need . Excel is an alternative CARBON source to using bottled CO2. Works well, but not as well as the bottled gas and over time(a long time on a 40 breeder) is more expensive

Here are my recommendations:

1. Do your research: Read up as much as you can before purchasing anything more so you can make your own somewhat educated decisions.

2. The MH question: IMO - Not recommended for a 40 breeder. It is unnecessary for that size of tank they create a bright spot that tapers to the edge and 36" is pushing the range and you will very uneven light. You should be able to pick up an entire 2 bulb 36" T5HO fixture for not much more than the cost of one MH bulb. Just my opinion, however I did love my mh pendant over my 24" cube tank.

3. Do some more research

Save yourself about a million hours of frustration. Sell the light and get something lower light that is easier to manage. Particularly if you aren't running co2.

But that leaves me to buy another light when I get ready to start up my SW tank. But that's a ways off though I guess.

If I were to do a DIY Co2 would the MH be okay?

Highly doubt it. That is a LOT of light and it will need a LOT of co2 and FERTs. You'd have to have that light way above the surface to keep it even remotely manageable.

Over a 40-breeder you can definitely use a 150w halide (if you have a 150w already). If you have a 250w or bigger, it's too much for sure.


Raise the 150w halide up about 12-15" over the water surface to start with, and definitely use DIY CO2.


Since you already have the light, you might as well give it a try.

And (speaking from opinion here) please don't buy that light in post #20. It's probably a decent light but power compacts are inefficient and costly to re-lamp. I have never liked anything made by Coralife for lights; they tend to be unreliable.... and I HATE power compacts. I would personally use a 2-bulb T5HO setup.

I briefly owned one of these that came brand new with a tank I bought from a buddy. I traded it for a water pump, but for the month I had it, I think it was a decent light for the money. Not a perfect light, but I don't have a biased grudge against Current USA like I do Coralife lol.

But really though, if you already have a 150w halide, give it a shot before you buy anything else.

And btw you can buy low-cost halide bulbs on Ebay that will work fine. They aren't the most efficient things in the world but they will do just fine for plant growth.

I would buy one labeled "10,000K" or "10K" since most of them look much more yellow than a true 10K bulb. Even good, higher priced brands like EVC 10K's are actually 6500K's according to the data I've seen.

For a tank your size you'll end up spending 500 bucks a year on co2 cartridges.

If cost is a big factor, getting something like an up aqua setup and a 5lb tank will work.

You can get an awesome reg/nv/solenoid if you piece them together from ebay and people here. Spend some time researching co2 and you regulators here and you will get a better idea.

Darkblade48 has a good primer on co2.

I don't know where to get what you just mentioned. So that's a big factor. Cost and accessibility. Like where would I get it where would I get it refilled and so on... would I have to buy it in pieces or is there a "starter kit" that I could get that has everything like the one I put up.

http://www.aquariumguys.com/turbo-co...174_a_7c207555 That seems like a good little set up for the new light. Cheaper than DIY but the same concept.
