I don't know the answer. I never test my waters, yet I still have breeding cichla. I do 25% water changes a day, no weekly changes. I smell my water, fell the temp...that is how I test my waters.
I run nothing but sponges and bio media in my filters and nothing else. So, I guess my answer would be more water changes.
