Water Flow

[new2dis]

What is the optimal amount of flow from return pump should I be running on 105g tank? Return also runs dual chamber reactor MR2.

what are the plumbing holes being used and what size of sump dimensions and baffles and do you plan on running anything in the future. Your sump will control can only handle a certain amount of flow along with your plumbing drains and returns. After that you can make a manifold to feed other reactors. including future reactors. The spec on the reactors website
will tell you the recommended flow though it.

The manifold has three outlets all 1/2 inch. One going back to tank one running reactor. Last one going to uv in future. Sump is about 30g and overflows are 1 and half in and 1 inch with the half about 3/4 open. Has one baffle going to return section. 3 sections in all. Running about 200gph on pump right now just wondering if I need more.

your only running 200 gph. I think you may have to turn over more sw in the tank. What was the reactors specs asking for?
and the uv? get those from their websites and that will get you in the right direction

what Shane said.

Though...I would think you made a typo and meant 2000gph, I can't imagine you being able to run all of that on a 200GPH pump....thought the reactor and UV are probably requiring next to nothing in terms of GPH.

The pump that I was looking at yesterday had serial numbers on it that read e1607. When I googled it the only I could come up with is a magdirve 1.9. I believe that is only puching 200gallons

Okay found another forum looking identify pump and I believe it is the same one Magdrive 9.5 and that is pushing 950gph.

if that's the case that would be the GPH at 0feet. How far is the water traveling from the return pump? This would be called your head height.

So, is this system up and running now? Just curious because I can't imagine it having much flow if any at all with a 190GPH pump which is most likely pumping at 40-100GPH after the head height is factored in.

If it's not up and running right now I would definitely look into getting something between 1200 - 2000 GPH. Even more if you plumb it to dial down in each areas. A pressure rated pump would be best if installing external is an option.

I have never used a mag drive 1.9 pump but if it is like all their other pumps I would replace the screws in favor of nylon screw which can be purchased at the hardware store. After several years the screws supplied with the pumps rust. Sometimes they make 5+ years but definitely something to watch for.

From Pump to the outputs into the tank is about 4 feet.

A mag 9 is much better than a little 1.9 lol You could probably get away with the 9 on your system depending on how you plumb everything. A reactor and UV are not going to take much flow to operate efficiently, low is usually best. Head height will be a huge factor for you though.

See my notes in my previous post about the screws.

If the system is up and running then do you think you have enough flow? If you don't you could always add a powerhead versus the trouble and cost of replacing a return pump.

System is up and running. I am running mp40 and a Hydor in the tank for circulation. I will have to check screws to see if that was already done. I purchased system after 4mo of it being up and running.

Shoot, with that MP40 you should be set for flow in the display! Not sure what the specs are for your UV and reactor but it can't be much. I'm thinking you are good but only you will be able to answer that one.

Thanks for the help!! Can't wait for the Frag fest.:wink_smile:
