Greetings all. My 46-gal tank has been established (rainbows, various small cats, rasboras, hillstream loaches) for over five years. A couple of years ago I tried live plants for the first time, and after some experimenting I settled on java fern and Anubias barteri, which are lower-light species (30w per 25 gal). The GLO HO single-bulb T5 light system that I got at the time of planting was too powerful for these plants, was too bright for my sensitive eyes, and caused the fish to lurk under leaves. So I changed the HO bulb to a Colormax NO T5. Everything was fine for about 22 months, and the plant-biofilter-fish nitrogen cycle was going well with fertilization. Algae was under control with snails, bristlenose and other cats, and hillstream loaches. Then one day the ballast died. The light was still under warranty, but (short version) Hagen does not make this fixture any more so they could not replace it with a new one. After much delay they sent me a check; slow process, but satisfactory. Amazon still had some units in stock, so I bought two successive units of the same fixture. Each died after a few days. I returned them both to Amazon as defective (also they were not packaged protectively for shipping). The upshot is that my plants have been without good light for about 4 months, and they are in terrible shape. The java fern in particular is in tatters. Each time a fixture dies, I've had to set up a jerry-rig system with two full-spectrum OTT lights, one standing and one task lamp. (These are excellent lamps for human eyes but are not intended for aquarium use.) They have been in place for several weeks since the last defective light was returned. Now I want to buy a new system for my tank that will properly light the plants and fish for their health and to bring out their beauty. I want to stay with lower-light species of plants; I don't want to use CO2; the substrate is medium-light gravel; and the tank takes a 36" fixture. Recommendations, please? I am willing to invest in a better fixture that suits my needs. Thanks!
