I have a 4-foot 47 gallon tank. I originally had a 56 watt coralife fixture (T5NO). I decided that that wasn't enough light, so I bought a second fixture of the same thing. I just got that one today. Well, I put it on my tank and....it's really not that much brighter. I'm disappointed! The lighting I have on there now comes out to 2.4 wpg.

My goal: Grow anything I want (assume CO2 and ferts).

Is my goal feasible with the lighting I have?

I was just on the Catalina site, and I'm contemplating returning the coralife fixture and getting a solar T5 fixture from Catalina. If I do go with that option, should I go with the 2 bulb fixture or the 3 bulb? It will not be suspended from the ceiling.

To recap, here are my two very important questions:

1. Is my coralife 2.4wpg enough to grow any plants I want (i.e. is this high light)?

2. If I get a catalina T5HO fixture, should I get the 2-bulb or the 3-bulb fixture?

I think that 2 of the T5NO fixtures should grow anything except perhaps the MOST light-hungry plants.

I run just one over my own low tech 46gal and it really brings out reds when plants get near the surface.

Ok, I've just done a very impulsive thing....

I just bought a 3-bulb fixture from Catalina. I'm terrible! I know it may be too much light, but they don't need to all be on. I can maybe run all three for a "boost" during the day. Also, If I ever get a 75 gallon, the 2-bulb fixture won't be enough. So...i'll consider this an investment :redface:

I did take your advice on the bulbs though. I got one each of the 6500, 10000, and plant grow. I hate it when the lights make my tank look yellow, so I hope this will be nice :)

My tank is only 18.5" deep. I have all my dry ferts, and I'm going to do DIY CO2 until I get pressurized (should be in January). I won't use all 3 bulbs until then. Even then, I won't use them all day, because i don't want algae issues. I'm new to all of this, so I don't want more than I can handle!

Off topic, but for DIY CO2, can I get the yeast from the grocery store, or does it need to be a better kind?

When I did the DIY CO2, I used champagne yeast which I got from a local brewmaster store. I read that it lasts longer and is more stable than regular yeast.

A word of caution about DIY CO2, though. Make sure you secure your bottles very well so they can't turn over. I learned this the hard way. My wife's cats knocked mine over one day and when I got home half the fish and all of the shrimp were dead from yeast mixture poisoning.

Another note, don't expect much from the DIY CO2. I ran two bottles for a 37g tank and I could never get the drop checker to turn from blue to green. The best I could do was a little aqua color. I had a pretty good diffusing method, too, that works awesome with pressurized.

Oh no! Thanks for the warning...I have two cats! I'll tape the bottle to the inside of the stand.

Wow, surprising about your DIY experience. I hope that DIY and excel will keep my new high light plants alive until January....

I found that I can order champagne yeast off of amazon with low shipping costs, so that's taken care of. Thanks :)

I appreciate your advice!
