I have a Cichlid tank and currently got a GH/KH test kit. The KH from tap water is 3 and GH is 10, KH from Aquarium water is around 8 and GH is 10. The PH level of the aquarium water is 8. I have crushed coral as substrate and I use one tea spoon of Cichlid salt everytime I do a water change. Is that good enough or should I be doing something else? Should I be worried about anything?
The tank has been running for about 4 months, but the filter that I am using has been used for past 2 years. The KH of the tank water is around 10 and I think that's because of the crushed coral. Should I worry about fluctuations in PH? So, far I have seen none.
