Changing Ph - answered my question!
This answered my question. Thanks, Raymond!
Last time I removed all the yellow stuff and this time I removed enough of it for water and air to get through - sounds like both were right.
Lenny’s reply was helpful, just hadn’t realized he was talking to me, and while I applied the principal it didn’t specifically speak to whether I should remove yellow gunk.
Someone else suggested the nitrate level should give clues. Either Raymond or Lenny explained that that might not work. Actually I thought that if it’s just decaying stuff that I should remove it might contribute to my problems cycling my tank, and if I did remove it and shouldn’t it also might contribute to problems cycling my tank. Actually I’ve always looked at that nasty stuff and removed it until yesterday. (Note that at the moment ammonia and nitrites are close to zero and nitrates are low.)
So I don’t need to remove all of it as sludge may contain helpful bacteria, but I want to make sure air and water can get through?
Yours, Dora
