I am also questioning on my return from the sump to display tank.I will be using a Mag 7; the overflow is fit for 600gph; unless I step it up to 800gph. The mag 7 will work for the 600gph overflow however if using the 800gph overflow I would upgrade to the mag 9.5. Saves me some money using the 600gph overflow along with the mag 7.

The overflow is CPR CS90 (600gph)
Return pump Mag 7 (700gph; 480 at 4ft, estimating 440-460 at 53" high for return pvc. My return would have to either have 2 90 degree elbow, or 2 45 degree elbows; now I know 45 degree elbows are less restrictive but would I still get sufficient flow from the MAG 7? Or should I upgrade to the Mag 9.5 using a ball valve to restrict flow? I can also use vinyl hose; however just looking for recommendations.

Possibly just using flexible hosing for overflow, unless recommended against?

Return pump will have 1/2" pvc, check valve; possibly ball valve (would this be needed?)

using the mag 7 which has a MPT outlet, so using a Female adapter fitting to slip would work correct? Sorry i am not the best at plumbing. I would then use a 45 degree elbow; another piece of PVC which would leave the PVC at a 45 degree angle exiting the back of my stand (if it will work properly); then adding another 45 degree elbow to direct the PVC pipe directly up. Then using a 90 degree elbow from slip to female adapter; which connects to a male 1/2" loc-line adapter. Sound good?

Then when using slip fittings I know of two items we have here in the house used to clean the end of pvc pipes, then glue to seal the pvc pipes. Maybe these aren't aquarium safe; advice here?

CPR Over flow
Tom Aquatics Aqua lifter pump
Aqua Lifter pre-filter (stops clogs)
mag 7
female adapter to slip fitting
45 degree elbows, (2) slip fittings.
90 degree elbow : from slip to female adapter
Loc-Line 1/2" ball socket with Male connector
Loc-Line 1/2" ball socket flexible tube
Loc-Line 1/2" flare
Ball Valve 1/2"
check valve 1/2"

As far as I can tell, the only plumbing I am missing is the actual PVC piping itself from the list.

Anything I am missing?

looking at close to $300 for plumbing lol. I think I will stick with a glass aquarium of 20-30 gallons.
