I am new to marine fish keeping, have done research and spent 8 weeks getting things started before adding livestock. Got temp, sg
, pH etc to withinn acceptable levels.
Have basic layout, sand base and rock.
added fish slowly.
4 Domino Damsels
1 Emerald Crab
3 Lion Fish
all has been going well untill 3 days ago
It appears as if there is smoke in the water, more noticable directly under light source. I have added charchol pad to underwater filter but that has not made much difference. All fish appear healthy and are still active and feeding.
would appreciate any hints on what the problem may be and how to clear the water
