    With high light it is easy to run short of phosphates, and when you do, GSA starts growing vigorously. The solution is to dose more phosphates - I used to routinely double the EI dosage.

    Surprisingly everything has been fine. I am running pressurized CO2 in the 29g now, and the plants are growing crazy. The issue is I am starting to see some GSA. I have had these lights on the tank for two months now. I'll try putting a layer of window screen on and see if that helps the algae issue. The lights are on right now for 8.5 hrs a day.

    Two T5HO bulbs close together, with a good reflector, should give you high light at the substrate (24 inches away, assuming 3 inches of substrate.) That is too much light for what you are trying to do. A layer of figerglass window screen would reduce that to medium light, which may still be a bit more light than you need. Two layers reduce it to low light, just about right. I'm assuming the lights are both T5HO, and that they overlap in the middle, by two feet. That two feet of overlap is even higher light.

    I suggest you try for only low light, not use CO2, and if you are concerned about keeping enough oxygen in the water, direct filter returns up towards the water surface to create surface rippling across the whole length of the tank.

    Would a solution be to put a layer of window screen under the lights?

    Hi Hoppy ,
    This is Ann7667 and I need your advice on lighting.

    Tank: 72"x23"x18" (23" high)

    Substrate: pool sand

    Fish: 7 Rio Tapajo Red Noses (geophagus) (2 are 4" and 5 are 7"), 6 4" clown loaches, 5 Cory dora juliis, 1 5" Ancistrus, 1 Juru Pari 7"

    Plants: low light 4 feet along the back half.

    Lights: 2 4-foot lights one has two Coralife T5 HO 54 that sits 4" over the glass; one With 2 Sylvania HG 28 & sits on the glass.

    1. lights sitting on the glass cause BBA so i will hang them instead. How high? Will my fish jump out?
    2. How much lighting do I need?
    3. With more light, do I need CO2?
    4. It is so important to me that my fishies are comfortable and have enough oxygen in that tank. What is the balance of light needed to grow low to medium light plants and Co2 needed to prevent BBA growth and leaving enough oxygen in my tank for my fishies to be comfortable.

    Thank you for your help!

    A 2 bulb Hagen GLO light sitting on top of a standard 29 gallon tank would be very high light. That is very likely to be too much light to ever get enough CO2 in the water to keep the plants growing well, if you have fish in the tank.

    Hi Hoppy,

    I was wondering if you could tell me if I have too much light in my tank?
    I currently have a 29g tank with a Hagen T5HO GLO Double bulb fixture. Standard reflectors that came with the fixture, and both bulbs are 24W 6700k.

    Thanks so much.

    Assuming this is a 4 foot long tank, the 2 foot T5HO light would give sufficient light on the portion of the substrate that is under the light, the middle 2-2.5 feet of the tank, with the ends being very low light. A four foot T5HO would give about the same light intensity, but over the whole length of the tank.

    Hey this is in regards to the thread "Taking it serious with a 55gal."

    I am so sorry to bother you with private message but i feel as if my thread will get lost in the mix, You said one t5 bulb with a good reflector and true HO ballast will be sufficient for my standard 55gal. (it was a rectangular aqueon kit), were you referring to a 4' t5 HO or 2' t5 HO? thank you very much for your time, i am just starting out and desperately need sage advice. There is a lot of information out there and it is a daunting task to weed through it.

    I don't recall seeing a one bulb Catalina light fixture, but I suspect they would make one if someone wanted it. They make most, if not all of their lights to order, so customizing isn''t a big deal for them. The "solar" lights are the ones I have seen data for, so those are the ones I always refer to when I mention Catalina lights.

    A 20L tank is so low, with the substrate only 10 inches or so below the top, that a T5HO light will always be too much light unless it is raised a foot or so above the top of the tank. Regular T8 lights would be a better choice for that tank.
