New 220g Setup. overflow question.

[Tinkerbell]

just as I started setting up my new tank my little giant pump seized. I've got a new pump and its 6000gph. I figure my head loss is about 12 feet. I have dual overflows. 1" returns with 2.5 inch drains.

my question is, is the pump to much for my setup? Will the overflows be able to handle the flow?  I have a 75 g sumptuous on the system as well.

any help is much appreciated.

thanks

If the drains can't handle it you can dial back the return pump

this might give some idea on it

You'll be fine with drains that size I have 2 one inch drains with a hammerhead and basement setup. Maxes out my stuff but 1 2.5 drain is huge

 

[Tinkerbell]

thanks guys. I Will see what happens lol. I sure hope it works out. I have a ball valve on it to restrict it again. Just got the pump home. Its a hayward pool pump. Its huge. My husbands all like "ugh ugh ugh" like Tim the toolman lol. We Will see how happy he is when the hydro bill comes. The pump was his idea cause it compares to the dolphin I would need but way less money. I sure hope its not too much flow for my corals and fish. I have two dual head powerheads that say they pump 3200gph each. I can shut them off till I dial in the flow. They only cost me $60 for both so ill even take them out if need be.

I shall let you Know!!!!

I need to modify it from 1.5" down to 1". Add a couple extra elbows to slow it down and maybe put it on the floor. Nice to have a pump but sucks to be back to plumbing the tank again. One stp forward two steps back. . . . .

Is that pump rated for a salt water pool.?...if not yu cant use it ..something about metal and copper.  Amd the seals will eat out in no time if there not salt water rated

 

[Tinkerbell]

its full plastic and rated for salt. the pumps seal can corrode over time but with the price being $180 compared to $400+ I think I can buy lots of seals

just do not restrict the intake to the pump.. keep the same size plumbing going in.  As far as output... are you going from 1.5 to a single 1"?  no way you can go from 1.5 up to the tank then split it into 2- 1"lines. 

 

[Neopimp]

just looked it up.... thats a 1 - 1.5 hp pump.

You are gogin to have a ton of water coming out that thing even at 12 ft.  the Reeflo Hammerhead rated at 5000gph is only a 1/3 hp. At the 15 ft of head I am runnign I am still getting 200-2500 gph out of it. I couldnt find a pump curve graph for that hing though so not sure how it will hangle the head pressure. 

When you fire that thing up.. make sure your return is pointed into the tank.

And have a camera rolling please

Maybe I'm missing something here...but generally the optimum sump flow-through rate is around 5x the DT volume per hour, with the "high flow bare sump guys" heading towards 10x.  Or are you also using this massive pump to run a closed-loop circulation system as well?

 

[Tinkerbell]

I'm real nervous. its plummed and ready to go. just gonna let the pvc cement cure for a couple hours. I already had half the plumbing done or I might have tried to do 1.5" up to two 1". but as it stands it is reduced to 1" then up and split to two 1" returns. both returns have two lock line directionals on them. no closed loop. I hope that restricting it Will give more time in my sump as I have a refugium in half of sump.

I went from not having enough flow to having too much. at this point I'm hoping my sand doesn't fly all around. good thing there are no fish or corals in the tank as of yet.

I was told I needed at least 6000 gph running thru the tank. I know it is probably overkill. if it doesn't work I Will have a brand new pump for sale or ill convince the husband I need a bigger tank lol.

 

[Tinkerbell]

Thanks guys for your help on this. I can't seem to find the right info. if anything I can plumb this thing half way across the basement floor if need be.

that's a really big pump but you look like your good to go for a test run, close that valve on the output if you need to a bit, It looks a heck of a lot like the same pump my parents inground pool uses. lol

 

[AdInfinitum]

Ok...so that looks like 2 x 1.5" drains (that is thick walled SpaFlex, not thin wall corrugated right?), not 2.5" drains...sounds more normal...each 1.5" drain can handle approx 1300GPH but at that rate it will be very noisy/turbulent.

+1 on the camera rolling...I get dibs on submitting the footage to AFV.

Approximately 20 x DT volume/hr + is the desired circulation number, meaning water movement within the aquarium from wavemakers, powerheads, closed loops, etc. not flow through the sump.


BTW, did Hayward give specs on that pump being safe for saltwater ponds or aquariums? I use a similar pump on my saltwater swimming pool, but that is a whole world away from the conditions in a reef tank.  The tiny amount of salt in pool water will already shorten the life of the pool pump and that is nothing compared to the effects that the high salinity, high PH, high carbonate alkalinity, and calcium concentrations have on equipment.

Brand new Pool Pump for sale! New in Box. Never seen water.

The pump is a Flooded Suction pump. Which means (after more research) it needs to have be lower than my sump. Unfortunately the husband (whom has nothing but good intentions) didn't know either. I don't want to move my sump to make a pump, that may not work out, for it to work.

Looks like another night in the 90 for the fishes. This set-up has been nothing but a total PITA.  Delays and obstacles.  Will be fine with my powerheads but back to pump shopping I go. I should have had a back up pump.

oh well guys no AFV. which would have been cool BTW.

to be continued. . . . . . . . .

At least now this information is out there about these pumps. THANK you for explaining that so well. 6 hours too late for me but out there for anyone that asks about it!

Cheers.

Good call...too bad we couldn't help sooner...

I run about 1300 gph through the sump on my 180 gal DT and at that I am upsizing my sump to to the 200+ gal range so that I can maintain that turnover rate in the tank but decrease the flow rate and turnover in the sump.

I was also headed in the direction of getting much of mycirculation from my return pump flow, but noticed Darryl made some very good points about separating circulation rates from filtration rates in other threads.

Find out what size of pump you need...you can look in the brs website at most f the good pumps ...they ship out friday night and yu will get it the next week ..or call the london stores see what they have ..i know the coral reef store in burlington  Has the waveline dc pumps and the blueline series in stock

 

[Neopimp]

did you even try and fire it up ?

a 1.5 inch drain is more than twice the size of 1".  Running under full siphon, menaing just water and no air in the pipe, you can run it wide open and have it be dead silent.  Its the air in the pipe that makes the noise.  I think a 1.5" drain running full siphon will move more than 1300 gph.  I was guessing up to about 2500gph, the chart posted earlier says about 2100 gph.  Either way, a reeflo hammerhead will fit the system nicely.  I knoew they are expensive Get the gold version if at all possible.

Anyways got more to type but I have to go to work......
