other question are pumps weaker pulling or pushing??? I ask because if they are equal I can put the pump after the filter to protect it from any damaging particulate, the tank will likely be sand so that is a huge plus if it worked out that way.

Pumps are weaker pulling. The lift height of a pump is always (I believe) less than its head height.
NO NO NO NO NO!!!!!!
Been there, done that! I have a Ocean Clear cartridge filter and it leaks. I replaced the O ring... still leaks. I pounded the screw lid with a dead blow hammer... still leaks. I replaced the lid... still leaks. I lubed everything over with silicone plumbers grease... still leaks.
Edit: this was using it with my 1/8hp pump. A smaller pump would probably not have the same problem... but a cartridge filter should be able to handle a decent sized pump!
If you want to go this route look at the NuClear filters. I have been told their locking mechanism is superior to Ocean Clear filter. Still, 25 micron vs around 1 micron for a DE filter.
My sump pump is a QuietOne 3000 I believe (might be a 4000). I will try to find some time to move my Hayward from the 1/8hp pump to the QuietOne then knock off all the DE in the Hayward to see what happens. The QuietOne is the smallest pump I have.
P.S. I am currently running the Hayward setup in a 35g hex... my 110g sprung a leak this Monday. I am hoping to find a suitable replacement for my 110g this weekend as my fish are kind of crowded in the 35 hex.
Thanks for the effort, sorry to hear about the leak, that really does suck!
the quiet one would be 700 gph, what is the flow you are running now? If all it takes is setting the DE in with more flow I can use my 1,300 GPH maxijet to do that then move it to the smaller one maybe...
My best guess after working with the Hayward DE filter is; yes a 300gph would work. The filter area on the Hayward is so large that it induces very little back pressure from what I have seen. The filter screen area in the Hayward is 25 square feet... but when charged with DE powder the filter area becomes many times the screen area because of the nature of the DE.
I did not worry about being able to pump water through the Hayward but rather charging the DE screens with the DE powder. The DE powder is so fine and so lite that I would guess a 300gph pump would be able to charge the filter screens properly... but that is just my best guess.
I wonder if this sorta thing puts up huge resistance and if it slows filtration enough it might behoove me to get it and try it on my maxijet 5500 first then if its to much flow for the tank step down to the 1100.
The pump I am running now is a pretty healthy industrial magnetic drive pump that came with a used industrial ultrasonic cleaner I bought several years ago. I just had it lying around so I put it into service on the Hayward. It is big enough to out flow the overflow on my tank. I will have to check and see how difficult it will be to swap to the QuietOne pump. I think I might be using a 3/4" return hose on the sump and I know I am using a 1" return hose on the Hayward DE.
