This is awesome! Can these be used as nitrate reactors (which have very slow flow and no tumbling)? I need a nitrate reactor but am having a hard time finding one for my 15g. Most of them are for 50g and up. Also do you have approx. tank size ranges for each of these? I'm looking to start a 5g or maybe 10g and of course I have my 15g.
Great work on these!
