i will observe them this week to determine if i should alter my flow by doing one of those recommendation. thanks guys!
i also observe that some of my petites are getting bba again!
i'm running about ~1 bps co2 by the canister's input, you can see at the first photo there is a black co2 line goes into the canister input strainer. this is one of my old fear that i might broke my filter because of accumulating gas inside, but it's proven to be wrong. thanks to jmhart
i'll post some photos later.[/QUOTE]
[QUOTE=ikuzo;7753201]that's what i'm afraid of,
i always believe that filter's input and output valve should always at full open or full off position. i'm afraid to damage my filter if i put the valves at partial position.
If your head height was higher than usual, but got the flow you are looking for, would you worry about it? If not, then restricting an output valve is the same thing.
yesterday i bought 10 pseudomugil furcatus and put them inside. they seem to be happy swimming around the tank and have no trouble with the current.
These fish require a tank of at least 12" X 24" and like low to moderate flow. I have some of these in my 75 gallon. I don't believe they are suited for a nano tank. They like to school and they roam all over my tank. They get in moods where they just want to be alone and take turns hiding in my plants.
