IIRC my biology, the plants will become a net consumer of oxygen when the lights are off. So, keep that in mind if you have a lot of plants and turn off your lights.temp is already at 88. turned heater down a little. i can add air stone i can take from another tank if needed but i have a hob filter agitating the water and have live plants , is this enough oxygen?
I vacuum weekly. There are also geos in there that move the sand constantlyBecause one of the stages of ich is a cyst that sits dormant in the substrate for some time, it is good to do frequent vacuuming, to remove them.
Just because there are no visible spots on the fish, does not mean ich has totally left the system.
