Oxygen.

[terryansimon]

probably trapped oxygen pockets. thats the disadvantage of adding sand first, then water later.

[ah^siao]

i added water first.. then sand.....

not sand first then water

[FuEl]

Oxygen produced by the algae.

[terryansimon]

yeah probably oxygen produced by the algae..

can't be your DSB matured within two months.

[ah^siao]

they are like coming up pretty fast.... hmm. those algae on the sand bed can clear away? wad are the best algae eaters for sand beds? i got couple of garden eels in my tank.. so my sand are being stured.. but very slowly..

[kschew1498]

try blue band goby! but it spilt the sand all over the corals if you have them on the sand bed

[ah^siao]

other than that? how does that goby looks like.. now my sand filled with algae..s o ugly.. how?????

where are the pros???

[kschew1498]

long long thin thin with a yellow head and a luminous blue stripe across its face and very shining eys.... very beautiful fish.....

[rouge_noir]

Yup... I have one and it dug itself a little cave under one of my LR. "splashed" lots of sad around

[ah^siao]
