I got my water tested 2 weeks ago and my ph was 8.2, nitrate 20, and GH was 7. My tank has been set up for several months and I have multiple peacock females that are proven breeders however I have never even seen any breeding like activity in my tank. The males dont even seem to be interested in the females. I recently have been wondering if this is do to my low GH ( ive been told it should be 10+) so I picked up some carib sea florida crushed coral and have added two nylons full to my aqua clear filters and a bit on top of my white sand. I am hoping this will help raise my GH but am also wondering if others think my low levels of GH are what has been stopping my cichlids from being in the mood. Any other suggestions regarding my method of raising gh would also be great.
