于 2003-09-22 09:57 I am using UGF and 2 桶 (5 sections) for my tank 42x20x22, open tank for 2 months, change water every 1 to 2 week.
Do I need to clean the sand every time I change water? Some people said clean the sand bed once a year or other said do it every time you change water.
Please give advice because I tried to clean the sand and after 2 days 4 mor died. I don't know if my tank is too new and unstable or if it is because I touched the sand bed.
