I am in the same old boat, I keep asking the same question, but apparently NO
one has ever had this problem or they just dont mind a brown rust layer over their white sand
It makes me think twice about having a salt tank. I love the fish, they are doing well, but the tank looks awful. I have posted this question on a few boards, but only get one or two maybe's (thank you for those!) One more try. I can change wanter sources, I can add chemicals, but someone has to have experienced this and fixed it. Right????
I have a 50 gal
salt, 4-6" sand base, two clowns, two damsels, coral beauty, small clean up crew. It has a custom filter and protein skimmer, perfect water when I test. I use Calligan water for additions and changes.
My tank is beautiful, EXCEPT, it always has a rust colored coating on the top of the sand. I try to reduce the lighting, (std lighting) and keep the blinds down. I thought it was the lighting, but nothing seems to help. It just "looks" brown and rusty on the top of the sand. I WOULD LOVE any suggestions on this. I want the white clean sand. My tank is over a year old and the fish have done excellent. My clown fish breed and I have siphoned off and raise clark clowns. Most everything is great, except that my sand look horrible.
HELP. I have asked this question before on another board, but no one has ever responded with an answer.
