Causes of pH increase?
I feel like I'm the Lemony Snicket with fish tanks. Could be because this tank has only been set up for two months, but I don't know.
Anyway! You know the drill, it's a 55 gallon tank with a medium number of plants and a medium bioload. My pH in my tanks have always sat around 7.2-7.5 with the water being straight from the tap 7.4. Well, I just got my liquid pH tester today and my 55 gal says it has a pH of 8.0. So I tested my tap water. Still 7.4.
Substrate and Decorations:
One-third is medium grade river stone aquarium gravel (something I got at PetCo)
Two-thirds is AquaQuartz pool filter sand
Pieces of driftwood that have been sitting outside for years, were soaked and cured before being put into the tank
Lots of Anubias plants, a sword, a Val, wisteria, Asian fern, and some crypts
Eheim 2217 canister filter
Marina heater (temp at 79F)
T5 bulb on 4hr, off 6hr, on 2hr, off 12hr
A dozen fancy guppies
Eight red phantom tetras
Two candy cane platies
So...anybody got any ideas? 😆
