100% agree with Prime, although honestly they are all almost the same even the ones from Tetra, Aqueon, etc. Prime just has the best track record for doing what it says it will do exactly to the T
So so we used to use water treatments and conditioners in our tank but to be honest we ran out at one point and realized that the tank stayed a lot cleaner without them I'm not sure why but it's a noticeable difference
I have been making use of API Stress Coat Water Conditioner and Tetra BettaSafe Water Conditioner for a while now and they both works perfectly well for my tank.
