mcgratda;2860137; said:Yea I had this problem about a month ago. I talked to the guy at the lfs and he said it was caused by my vacuuming gravel and changing the filter cartridge at the same time. he told me in a couple of days it would go away and it did.
No matter what filtration you have if you clean to much your tank will get a bacterial bloom. Heck i vacuumed 1/3 of my gravel and did a 50% wc the other day and i got a slightly cloudy tank. Its been established for a year and a half and is OVER filtered. Just dont do as much and you should be fine.
PS: BTW im running an Eheim Canister filter, Penguin 350 HOB, and an undergravel filter.
