ph dropping and nitrates rising
So Ive been having this problem where I'm fighting my oh and nitrates for a couple of weeks now. I do water changes weekly along with regular cleanings but all of a sudden ph drops to 7.4 and nitrates rise real high about three days later I get it all balanced back out.. I use a buffer called eight.four it helps but I can't figure out what's going on.
