I think you will find them to be powerful yet gentle. Great upgrade.If anything it will be less flow.
i had a vortech mp40, and a hydor k3.
tunzes should be nice and quiet and provide nice alternating flow ;)
i think ill run 5000lph through each tunze constantly alternating between pump 1 and 2.
if i need to i could also leave the hydor in there to
I want to see that Goni dance. mmm mmm mmm mighty fine :drool
I think I've got pump envy LOL
