Ph Keeps Increasing

    Hi, Iv been having issues with ph rising in my aquariums. Most of my aquariums sit at 6.8-7 only after using fluval stratum as the substrate. Recently I have set up a breeding tank which is in the process of cycling. As it is a breeding tank it is a bare bottom and I don’t have the fluval stratum to bring the ph to level that I want.

    I have tested my tap water and let it sit for 6-8 hours before testing to see if it changes, and I got the same results. Water from my bathroom sink comes out at 6.8 and water from my bathtub comes out at 6.6, which is kinda weird?

    Now when I water change my aquariums and add conditioned tap water, over night the ph in any tank without fluval stratum will rise to 7.4-7.6. Sometimes higher if I leave it long enough.

    I thought maybe it was the addition of aquarium salt causing the ph to rise, but I haven’t put any in the breeding tank and the ph still rose to 7.6.

    I’m at a loss and just can’t seem to figure out why I keep having this issue. At the moment the breeding tank has no rocks or salt, just an Anubis plant, java fern and some moss balls. Along with a heater and a sponge filter. The only other thing I can think of is that maybe my water conditioner is increasing the ph? I use Nutrafin Plus.

    Any ideas are greatly appreciated. Thanks!
