Ok I've gotten rid of all my fish bc of tank size and being unlearned in cycling... However I still have small common pleco who I'm hoping to donate to someone asap. I did a pwc on the 20th and tested the water that day and tested again today... Still about the same and I've had the tank for close to 3 months and have had fish in it on and off.. Ammo levels are around .25 does that means just now starting to cycle??? What if I give the pleco away and throw in a shrimp??? Will that help ??
