Very bad week for the tank... sudden ammonia spike to 1.0 been worried me. Not sure what the main cause. Believe it was cause by dead Anthias and several corals before. Maybe causing by mini rock arrangement? I dun know...

Just realize this bout last week during the water changed.. already done several WC as for now. Now its worsen with another ugly thing appear on the sand :( brown algae! ... yet another coral die! Not sure if its die because of something else but ammonia spike sure 1 of the main cause.

The only good thing .. other parameters are stable... hope its not as serious as i think.

Have to do more WC after this ... damn its tiring! Bought another big big "tong sampah" to store more water change. Will continue on tomorrow or this weekend ...
