Although I’ve been doing fish tanks for years, I am a complete novice when it comes to planted tanks. It’s the one big thing in the aquarium hobby that I haven’t tried. I have a couple of questions regarding my existing equipment. The tank I’m using was a 55 gallon reef. It was beautiful, but got to be way too much work. I’ve scrapped off all of the coralline algae and salt creep. I think I’ve got it as clean as it’s gonna get. Are there any other precautions I should take when using a tank that previously contained saltwater? Second, I know my 2 x 175 watt metal halides are a little much for a planted tank, but I do have a Corallife 4 x 65 watt fixture. I has 2 on/off switches. What bulbs should I use? I could care less about the color. I want to use whatever is best for growing plants. Nothing fancy. I’m not trying to win any awards. I just want the plants to grow. And before you ask, yes, I’m going to use a CO2. Any help is appreciated.
