| | Ph boost in new soil tank???
I recently setup my first planted tank after being out of the hobby for some time. I only had one other planted tank before this one. I had tried "high-tech" and I wouldn't have called it successful, so this time I'm going more "low-tech."
Tank: 29g with soil (MG Organic soil for raised beds - I know it's not potting mix, but it was the only organic soil at home depot at the time of purchase) bottom with a roughly 1" pool filter sand cap. The tank ran for a few days without any inhabitants because I was waiting for plants via mail. Now the tank is planted moderately (at least that's what I'd call it because once they grow out it will be full). I have 7 Rasboras and a couple sailfins that are native to my area.
Question: my tap water is 7.1 but my tank is up to 7.8 ph. My worry is about my native sailfins because in the evening they show signs of distress (gulping at the water's surface). The rasboras seem fine and so do the natives in the morning (they only seem distressed by gulping in the last couple hours of light in the evening). What could be causing the sailfin distress? and is this rise in Ph normal in a soil tank?
