I have a small 10 gallon aquarium that has 15 pounds of LR, 2 Blue Damsels, 6 Blue Leg Hermits and a Scarlett Skunk Cleaner Shrimp. I have TWO 20 watt 50/50 10k/actinic bulbs over my tank. I plan on adding some low/medium light corals in my tank but I seem to have problems with brown sand or Diatoms. I do not have an RO/DI unit yet hence the reason why I haven't got my coral. My tank is cycled...so what is the reason for all the diatoms? I seem to keep coming, but only where the light hits. What can I do? It's unsightly.
