I have a 55 gallon tank and will be getting my XP3 soon. If I use the sprayer attachment (or the power jet?) would I also need to purchase an air pump for fish I plan on putting in the tank?
Also, how close has anyone placed the unit to the water level? I am using a coffee table right now and would probably have to build a stand if I wanted to get the water level a minimum of 24''. The coffee table is probably between 12-16'' if my memory serves me correctly.
