Since adding pothos to the top of my tanks I see less signs of higher nitrogen. So if possible adding some sort of plants may help cut down on the nitrates. We are in farm country too, and heavily filter our water.Also you mentioned not cleaning your decorates, maybe that had something to do with it because only recently..in the past couple of months I started rinsing them off more often and placing them out in the sun and rain for a few days, because they reeked of fish and some had algae I couldn't get off. I never did more than rinse them occasionally before that. I read somewhere that was the thing to do...putting them out in the sun certainly did get them clean though.![]()
Removing and cleaning one item at a time is okay, but not multiple items. You probably removed too much bacteria. Removing some bacteria by routine cleaning is okay, but too much can cause conditions to get off balance.
Here our water comes out of the tap more acidic, and than buffers up to alkaline after being in the tank for a while. Even the water guy couldn't tell me why it does that. Our water also gets more acidic during the winter months I suppose because the water table isn't being refilled and diluted like in the warmer months. All thing I didn't know before I started keeping fish.
