Nope. I don't use live rocks that's why. U can see a ugly green algae too. I recently hv done a 50% water change coz of ammonia. U can see detritus also in below pics. I hv hydroids,sponges,more coralline,bristle worms and sphogetti worms,vermetid snails. I am just worried about loosing a coralline algae in one place. Also how can I remove that ugly white colour it is leaving. U can see more pics in my threats. I just keep my mirror and back black background clean coz it gets green algae and brown detritus
