I am having a very very hard time finding out what the correct PH level should be in my tank and was wondering if my PH being a little high could be killing off my blue rams. I have a 92 gallon corner aquarium that I started off with having 1 stingray, 6 blue rams, 8 discus. The discus and stingray are all still alive but 4 out of 6 blue rams have died in the last week. My PH is currently holding around 7.8 and every website, pet store, and the breeder I bought the discus from all say completely different levels for PH. I read online for well over a hour last night and every website has different ideas on how to lower my PH or what it should even be. I even did a lot of reading on yahoo answers also for PH levels in aquariums for discus and everyone who asked questions got different answers on levels and how to lower it. The discus were bought from a breeder the blue rams at a local pet store and the stingray also came from a pet store. My brother has been in aquariums for years and has lots of stingrays and other fish and his PH in his tanks is holding around 7.5 but he doesn’t have much knowledge on discus and blue rams. Here are my levels in my tank as of last night Nitrite 0ppm, Nitrate 5ppm, Ammonia .2ppm, PH 7.8, 82 temp, two canister filters with UV lights, 2-18″ air curtains. Can someone please help me I am worried if my PH is to high I am slowly killing my fish and maybe the blue rams being small it affected them first.
The ray is small and is not eating the fish. Everytime a blue ram died I found there bodys floating and had to net them out.
I have a hystrix ray and it is about 4″ right now
