Thanks I was liking that design better too. The flow is more open and seemed less prone to clogging. I think its a go with that unit.
I found supporting info on this being a good unit and the other being prone to failure!
I have ordered the unit and plan on hooking it up to a marineland 550 powerhead I believe its rated at 148gph. putting it right in the range of 100 to 200gph needed. I plan on using a sponge prefilter and hopefully a minimal amount of tubing by hanging it close to the top. Anybody have a guess on many gph
should be expected with this type unit. 3 factors will affect the gph
. about 12 inches of tubing, the turbo twist unit, the sponge prefilter.
