Hi! I am still learning and my tank is about 4 weeks old cycling still. 55 gal
tank, 2 large pieces of LR
and live sand. My levels are reading
Ammonia: 0 ppm
Nitrite: 0.25 ppm
Nitrate: 10 ppm
They were good yesterday, so I'm not sure what would've caused this sudden spike? What do I do to balance them back out?
Any help would be greatly appreciated as I am loving to learn about all of this! Thank you!
