[sparks1107]

same happened to my sandbed recently. did u just introduce phosphate media like i did? i suspect its the anti-phosphate spills from the bag. donno whether is it harmful though. afew of my fishes died after having this. not sure whether its my water condition or because of the sandbed. anything happened to your tank yet?

[raydiative]

looks like brown algae and cynao... have you been overfeeding ur tank? what are your parameters? possibly too high in nitrate and/or phosphate... do impove the flow there..

[tagie_tag]

to bro weihao. u rite i recently change my FR media.

yes it might b over feeding but i now feed them once per day, is tat overfeeding?

may b my flow no good enough.

will change of water often will get rid of the brown stuff. now my rock got tis problem. c pic.

water change will reduce the level of nitrate and phosphate (suppose your new water has 0 phosphate).. this will help to control and reduce the amount of algae.. IMO, changing of media should not cause this... =]

[sparks1107]

maybe its the high level of nitrate since bro ray pointed that changing of the media wont affect. i tried playing around with the sand to cover the brown algae. think changing of water can reduce/maintain the algae from growing. but whats there already there. saw my algae blenny pecking on those brown sands as well. so it should be the high level of nitrate that caused the algae bloom in the sand. any casualty in your tank yet?

can try using a sand shifting star to solve this prob. also use only DI water for ur water changes

[tagie_tag]

to weihao so far no casualty on my tank just lost one of my xpensive prata.

will turbo snail and hemit crab help or any invert can ?

but not urhin it look ugly to me ...hehe

[sparks1107]

ouch

anyway, u tested your nitrate? didnt have nitrate test with me so didnt test mine. my sandbed is so dirty + ugly now

[sparks1107]

dont think snails and hermit will help unless u have lots of them.

Hello mate ..... hv been there in the past ..... my suggestion - change water , suck away the algae on sand n rocks. Off lights for 3 days ( 2 days if u hv sps or anemones just in case but for me even my sps n anemones no prob with 3 days no light )

agreed.. sand dollar will help as well... i only use distilled water for all my water change and during my startup... do wanna take any chances... =]

they might feel stunt if i wrong or mayb worst. can anyone senior ppl there can verify tis point.

Feeding frequency does not determine overfeeding. It's possible to overfeed with once-a-day feeding.

Generic rule of thumb is to feed only the amount that your livestock can consume in 3 minutes. Any leftover becomes nitrate factory.

Even if all the food is eaten by fishes, if they have eaten too much, they will purge partially digested food to accommodate the new food eaten. partially digested food are also nitrate factories.
