I have a lot of light on the main tanks and a good amount of floating plants to go with them.

I would reduce it to at least 8 hours (Like Jayy is saying) for now just to see if you get a good response. Then you can maybe raise it to 9 or 10.

Ok, that sounds like a good idea. Just don't want to starve my plants for light especially since they are so new and I want them to establish well!

Remember the balance: plants can only use the light if it is balanced with nutrients. So more light (duration) does not mean improved plant growth, but may be the opposite, and encourage algae as I believe it is here.

Plants can do fine with as little as six hours of overhead light provided it is of sufficient intensity for their specific needs and the 17 nutrients are available. More light duration is fine, but the nutreitns must all be present accordingly.

Thanks for the info Byron, I still need to figure out if my lighting is appropriate for my tank as I have my doubts. The more I read the more confused I get about what is right and wrong about my florescent lights and how many I should have and how much brighter the HO bulbs are and all that stuff. Tomorrow sometime I'll figure out exactly what fixtures I have in there and I'll post it and see what everyone's opinions are.

Oh, and I've meant to mention for a while but last week with my last batch of plants some trumpet snails hitched a ride in! I'm enjoying them a lot and they are fun to try and find in the tank. I think there are three and I'm hoping they are doing a good job sifting sand and doing some general cleaning.

There will soon be many more than 3, I assure you. I have hundreds in my tanks, and I am glad they are there. The work they do in burrowing through the substrate, digesting waste and assisting the bacteria is very useful.

When you post the light fixture data I will respond on that.

Ok, so what kind of lighting I have is still a complete mystery to me but I'll put down what I know and maybe somebody can tell me what I have or point me in the right direction to what I should get.

There is a T5 lighting fixture that I really don't know whether it is NO or HO with 2 bulbs in it. The first bulb we discovered earlier to be a

http://www.amazon.com/Life-Glo-II-Fluorescent-Bulb-Watts/dp/B0017JHD12/ http://www.amazon.com/Life-Glo-II-Fluorescent-Bulb-Watts/dp/B0017JHD12/
The other bulb in there is an Aqueon T5 36" 21W bulb at 6700K.

There are some pictures here for reference:





Any ideas what I got or if I should be looking to get something different? Thanks!

Going back in this thread, i see we did look at this previously, but now we have a bit more info. I'm fairly certain this is HO light, the linked data says this (on the package) and it makes sense, so we'll assume that it is T5 HO. This is a 75g tank, and the tubes are 34 inch, so using both should be manageable. Duration might have to be less, particularly with few plants, or you will have algae soup. The Life-Glo II is a good tube, expensive but good, I use the T8 Life-Flo as one of two tubes over my large tanks and the only tube on my single-tube tanks. The Aqueon tubes should be near-identical so it is fine. When it comes time to replace these, you could do one 6700K and one higher Kelvin, or stay with two much the same (6500K-6700K).

I see no reason to spend money on another fixture, if this one lights the tank. Lots of floating plants. Tubes need replacing every 12-18 months, they lose sufficient intensity to be risky after that.

I agree with Byron that the amount of light you have now is more than enough.

Great! Not having to spend money is always a great thing, glad my lighting is adequate for my plants. The algae is beginning to die off a little it seems, I'll post some pics of the progress once it is pretty clear so you can see how bad it got! ha
