Product Questions

What size fitting are the inlet and outlet and Hose verbs on this reactor? I assume you would want to find a pump with the same size outlet to make plumbing simpler.

How many gallon tank will this support?
Question by: john on Apr 12, 2014, 3:33 PM
Hey John,
It really depends on the type of media you want to put in it. It can hold up to 2.5L but depending on what that media in, 2.5L might be enough for a 5g tank or a 500g tank. With most medias its going to work for all but the most giant of tanks though.
