Recently I bought a 5 gallon pico tank in hopes of making it into a macro alae tank. I have never had a macro algae tank so I had a few questions on how to start. First I have a cheap $15 nicrew fresh water light from an old tank, will this work on a macro algae setup or will I have to purchase a more expensive light if so suggestions would be great. next do macro algae need specific flow or does it generally stay the same? lastly are chocolate chip stars safe for a macro algae tank? I have only found a few articles from over ten years ago and they are all giving different answers.
