What water conditioner are you using? Are you adding anything to the tank besides water conditioner? What type of food are you feeding?
your tank looks nice but if you don't mind a few suggestions I would add a cave and possibly a heater. Bettas really need places to hide to feel secure and they need temps from 76-82*F... just some things to think about for the future :)
Sounds great! I have a divided 10 and you won't believe the transformation he will go from being in the small container (I have one similar to yours) to 5 gallons.. mine were like whole new fish LOL.
I think my question was phrased wrong.. is your food flakes or pellets? I've heard some flakes can cloud the tank if you over feed. I think the aqueon is pellets but I could be wrong.
I would just let it settle for a few days to see if it goes away.. I really can't think of anything that would cloud your water. Some water conditioners will but I've tried aquasafe before with no problems.
