What is the best way to encourage coralline algae growth on live rock in a fish only tank? Specifically, what is the best lighting (intensity, spectrum, and photoperiod), additives, etc.?
I've had my salt water tank up for 8 months now. For the last 2 brown algae has taken over. Now it's out of control. It's growing over everything, and getting so long it looks like hair. I've done water changes, my water levels are normal, my crabs have all died, and there are no snails left.
Can real ocean water be used during water changes. I live near the ocean.
Do I need live sand for my tank?
