Set up a 5 gal tank for apple snail and 2 ghost shrimp. It was cycled. Ph 7.6, Ammonia stayed at 0, nitrites 0, nitrates 20-40. But then I noticed the ph dropped to 6. I thought this wasnt great but nothing too big. Then Ammonia went up to 1.0 and no Nitrite reading. I was using reverse osmosis water for weekly changes. Would this cause a low ph? And then cause an ammonia spike?
