29G - F20 6500k Fluorescent Bulb (20 watts) and a 23W 6500k CFL Bulb.
20G - F15 6500k Fluorescent Bulb (15 watts) and a 23W 6500k CFL Bulb.

The CFL's are much brighter than the fluorescent

This is the CFL Bulb: Shop SYLVANIA 2-Pack 100-Watt Equivalent Daylight Compact Fluorescent Light Bulb at Lowes.com

I did this to the 20 gallon and the 29. It's the stock overhead light and a desk lamp with the new bulb in:


Is this too much light?

Depends on the plants and fish. Just what I see in there I would say yes. I think you can remove the desk light and have plenty of light for the majority of your plants.

Maybe. But you have higher-light plants (Wisteria, Cabomba) so this might be needed. I would monitor it for a time, for algae. But not knowing the fish, floating plants might help.

Just wanted to say thanks for the help and advice! I try and help on other forums, and sometimes it bugs me a bit when you try and help someone out and never receive any feedback on how everything turned out. Sometimes your just curious to know...

Well, made a trip by petsmart planning on a single T8 light and came across a damaged (box only) T5 NO light. So did some quick research and from what I understand a T5 NO (48" 28 Watts) has the same output pretty much as a T8, with the significant difference being the price and lack of T5 NO bulbs easily found. After talking to the help there, they said they would cut me a deal on the light since the box was damaged. Being a bit slimmer and price reduced, I went ahead and grabbed it. Looked online first and found T5 bulbs on Amazon for a good pice (I think). 8 bulbs for $47, comes to about $6 a bulb and I figure that one order should be enough replacements to last me a while. Going to wait first and see how this one goes though, in case I decide to return it and grab a T8.

Bought some spacers from Lowe's and raised the light 5" off the glass, and the fish seem happy with it for now. All the remains is to wait and see how the plants react as well as if the fish stay healthy and happy.

Thanks again to all who helped, and more than likely I will be pestering for help here again :)

The results of my first attempt at a planted tank with the new lights (for now). All plants real except for the two in the far lower left. If everything stays happy, will replace those shortly as well as add some moss:

Someone needs to tell my plants that They're growing fine with 98 watts over a 125 gallon aquarium.

Don't mean to step on toes, but the watts per gallon rule dosen't work.

Looks great. DO you have a picture of the spacers you bought from lowes or more details? I was thinking of getting the same thing (spaces) for my lights and want to see what you came up with.

Thanks Termato! Yeah, we are going on a camping trip in the Frio river area (Texas) next month. I'm planning on keeping an eye out for some rocks or wood for the tank :)


Twindad, I will see if I can get a good picture of them after work. What I ended up using are actually adhesive anti-skid pads used to stick on the bottom of furniture and such. They are approximately 1"x4"x1/2". Stacked them to the height I wanted (since lowered to about 2") and they are working perfectly. No slip and stick to the glass was perfect since it took the worry about the light being easily knocked off the risers away (I'm kinda clumsy sometimes, lol).

Hey Twindad, sorry for the delay. It's been a busy week and we are just now getting a chance to relax. Few beers and a brisket on the pit :) Here are a few pics of the "spacers" I am using. They are now only about 1" off the glass.









Hope this helps!

I can't tell from the photos...does this tank have a permanent centre brace from front to back at the very top? I can see the plastic runner guide for the cover glass, but this (on my tanks anyway) is just suspended between the back and front frame. If this is the case, you should not place the weight of the lights on the cover glass, it can cause the centre runner guide to bow and this could result in the glass dropping into the tank and then the light which could electrocute the fish and possibly you. The light fixture must be supported by the main tank frame around the top.

Hi Byron! Yes, the tank has a center brace. The original cover was two pieces, with two light fixtures resting on them. I purchased two glass covers which fit the space with barely a mm to spare. Thats one of the reasons I wanted to raise the light, so it wouldn't rest on the center support.
