Thank you Chad,
I will use just a maxijet 600 since my tank is so narrow. Or should I go with more flow? So I should get rid of the biowheel and use a gfo to remove phosphates and nitrates? The protein skimmer will remove the filth in the water. I heard of people doing that but I was a little wary of doing that.
My lighting isn't strong enough for algae and I will probably keep it that way.
Great tip on not buying the seahorses based on color. Where is a good place to buy them?
