@najer 28" long. 4 heads. Rfg on each head? That could be fun to do!
Safe and enjoyable trip.
Different scale, the s tank is 13 G, it runs an Eheim 1000 flat out with a twin duck bill return, no powerhead!
You would need to make them able to be aimed, to a degree, I just figured out how to do that as I typed btw, where was I, oh yeh, if you / we can figure out the correct adjustable return it could easily be powerhead free!
