A couple weeks ago I set up new 5g tanks for each of my bettas. (2)
They are the Aqueon 5g mini bow tanks.
I used API Quick Start to get them started and added the fish a couple days later. About 4 days later the water was cloudy. So I dumped the water, cleaned everything and started over and put new filter media in. The same thing happened, a few days later and the water is cloudy.
The water tests normal. I've used API in the past when I had 2g tanks set up for them w/o filter and not had this issue.
What am I doing wrong?
