Step 5Summary

I'm very keen to have my tank as clean as possible in terms of technical equipment. At the moment I've got only inlet/outlet pipes from canister filter and that is obviously minimum.

If you'll have good combination of background and pipes colour (black background, black pipes for example), the pipes will be almost not noticeable.

Next time drop checker, for checking CO2 level in the tank.
Good luck!
