ok. not to sound stupid here but...
1) does that mean that i need to replace the sprayer that came with it with a spray bar?
2) if i use the sprayer that came with it, it doesn't seem like its set up to break the surface tension so what then?
3) this just popped into my head... using the sprayer that comes with it seems like it would create a current inside the tank. is there a certain way the "current" should be setup?
this switch to a canister filter is going to take some figuring out.
Canisters can be intimidating at first, so that's all understandable.
1. No you can use what it came with in almost all situations.
2. What kind of filter is it? All there needs to be is a slight ripple at the surface. Spraybar can be angled up towards the surface if it sits too far below the water line.
3. Yes current in a tank is generally a good thing. My preference is to have the spraybar mounted on the side glass so that it pushes water across the length of the tank. On larger tanks I use two canisters to creat a circular flow in he tank. It's a far more natural current for the fish to live with than having the outflow smash against the front glass, which is how many people have them setup. There's nothing really wrong with doing it that way, but I do think a more linear flow is better for every aspect of keeping the aquarium.
