Is this enough return gpm?

[porpoiseaquatics]

If you have a 180 with standard dual overflows....is 2100 gpm a good return rate?

 

[ripped tide]

That should be fine.

If not a bit much.

I'd probably use a manifold and power a reactor or two.

 

[porpoiseaquatics]

Would 1500-ish be better?

 

[gmpolan]

Realistically you only need about 1000 gph for the return, but depending on your manifold, either of those would work.

 

[ripped tide]

I run 1200 on my 210. That's between 5-6x an hour.

On my 93, I also have a 1200gph, but it feeds media reactors and a frag tank as well. I estimate that the display has a turn over of 5-7x per hour.

 

[gmpolan]

Yep, most should be anywhere from 3 to 6 the turnover per hour

I run a quiet one 6000 on my 125. Flow is 1660 +/- I know it is over kill but I think I am good no matter what reactors I put on it in the future.

If the overflows will handle it why not?

 

[tchristman]

My personal preference is to create flow inside the tank with powerheads instead of worrying about how much return pump is creating. I run 3 Vortechs on my tank and use sea swirls for the returns. I try to turn the tank over with the return pump only 2-3 times per hour so that water can actually be filtered in the sump. Also, it generally makes the tank quieter because there is not as much water banging down into the sump. Personal preference.

Hhhmm...then I may have a brand new Quiet One 9000 to sale soon. At over 2100 gpm...it's probably going to be to much even from a manifold.

Depending in price I may take it. . Never hurts to have a back up and I plumbed a ball valve in the return.

I'll let you know if I decide to get rid of it. It'll be a couple of weeks before I get everything plumbed up and determine what I need. If I do sell it....probably somewhere a little south of $200.

Im running a reeflo dart but have it dialed way back.

Less flow going through overflows has some advantages-

-less noise
-less evaporation
-smaller pump
-less heat ^

Mainly the advantages of an overflow is to-

-remove and filter 'surface scum' due to fats, oils, fatty acids, surfactants, etc.,
-provide nutrient cycling, and
-gas exchange.

The trick is to balance these. I agree with the ~5x target.

Jeff, my reeflo is way overpowered and is dialed back to only about a 1/3. I actually use a seperate pump for the manifold, so you should be fine regardless with some adjustments.
