Aquatop CF 400 UV Canister Filter questions
I just installed this thing, it seems to be working great but I have a few questions.
1. Hosing: I tried straightening it out as much as possible but there are a few curls (not kinks) in the hose. I reduced the length of the intake after multiple failed attempts to self prime the system. After shortening the hose she it self primed no problem, I know that a hose that isn't straight can cause unnec. head pressure, but I dont think how mine is set up will cause any harm, anyone can give their best guess if they want to lol. It runs ultra quiet and doesn't seem to be struggling atleast.
2. Filter changes: I do weekly water changes and am familiar with taking the media out and giving general rinsing. When or at what point should I change the media? I was told mechanical is 6months, carbon is 2-4 weeks optimal, 2-3months is okay and not sure about the ceramic media.
3. UV light: should I only use that when there is algae in the tank? My oscar previously had some slight build up around the eyes, maybe ich? not sure if the UV light even battles that type of bacteria, but what and when should I use the UV light for?
