do you still have them?
how do you like the new pump "vortech" did you get two of them ?
i was looking in to them but it was too much money for me and i heard they had problems over heating on the out side part.
i have 1 vortech and one k4 on the other side of the tank now. the vortech is awesome and i got it for $200 used from a guy with glass a little bigger then 3/4" so it wouldnt hold on the glass. I wish i could get another one but i dont want to pay 400+ for another one right now. It does get hot on the outside but it doesnt heat my 90gallon up at all because the rubber between the glass and motor doesnt allow the heat to pass through the glass.
and yes i still have 2 k4's for sale.
I am workin on a tunze I just told him I would take them so I was hoping someone else would take them BUT i AM A MAN OF MY WORD i WILL TAKE EM IF i NEED TO sorry about caps my bad
