I bought two amano shrimp from my LFS that died 2 days after I bought them. They are willing to replace them, but only when I lower my ph (7.8) because they keep theirs at 7.0 and think that’s what killed them. After a week without getting it to budge, and testing my tap water (7.2) and my empty QT (6.6) I decided to just get a 3.5 gallon that was on sale as a second tank and go from there. When I first set up my 10 gallon I just got some cheap aqua gravel from Walmart and I’ve wanted to upgrade for a while but since it’s heavily planted I was going to put it off until I had to move it or do something else major. Since the tanks will be next to each other I was researching a bit since I wasn’t sure if the quality and price was better than them matching and discovered that it was that cheap gravel that was raising and keeping my ph high! I would just leave it at that, but another reason I wanted to lower the ph is so I could get some tetras in there. They would be in there with my 3 adfs and shrimp. Would it be worth spending a weekend to rescape? Would replacing all the substrate mean I’d have to recycle the tank? I’ve had a large piece of driftwood I want to put in there, and it would be nice to have some more thought put into the design than beginner me did just trying to make it work, so it’s no completely about lowering the ph for the sake of it.
