This week diatom bloom start! .. ermm i keep remind myself nothing to worry about this .. its also happened last time and its a must for newly tank setup :D

Right now brownish color only spread on sand bed .. so i think its not so critical compare to last year tank. Its spread all over sand and rock!.

The situation getting better today .. still have a lot of them but the color absolutely lighter compare to yesterday.

As for now .. i just reduced light period, super wet skimming and doing WC normally.Maybe next WC will siphon out diatom if its still there .. hopefully no lah ..

For Diatom reference :
