Idk how many of you are familiar with snakes, but a couple months ago I received a trio of Banded file snakes, Acrochordus granulatus, and I've been keeping them in a tub with no filter but frequent wc's. These guys require extremely acidic water so I've been maintaining the ph in the tub at 6.0 while I'm getting the aquarium all set up and cycled. Problem is that I cannot for the life of me keep the pH stable at 6.0!!! I've been using seachem acid buffer to lower the pH but within an hour or two it jumps right back up to 7.0. I also have driftwood and almond leaves in the tank to add tannins and drop it but they're not helping at all. In the tubs with no filter they're completely stable but in this tank with filtration with very low flow, it will not. Ideas guys! And here's a pic of them
