I have a 29 gallon planted tank (very low tech, no co2
, average light). The ph seems to be always at the max threshold on the API test kit kit chart
which seems to be 7.8 maybe even 8. this seems very adnormal for a freshwater system given I do nothing whatsoever that could buffer the tank. It matches my source water but doesn’t the ph of tap water gradually acidify after being added to the established system anyway??
Other parameters in case they matter:
Ammonia- .25 ppm
I keep mostly South American fish such as catfish, tetras, an angel I’ll probably rehome soon anyway due to size, and dwarf cichlids. Everything in there now is fine, mostly because they’ve adapted to it. But getting new fish can be a struggle sometimes. I do monthly water changes and add seachem root tabs every 2 months, dose flourish comp. once a week, and iron and potassium every other day.
