can i run myreef skimmer from ampmaster

[naser]

well im using the amp master for my return pump.. what i want to know is can i t off the line and feed the myreef skimmer? myreef says the skimmer need 1800gph. i only have a 1.5 inch drain so i wont be able to use the full power of the amp master anyway?????

[myreef]

Neil, You can do what you want. Here is a thread on RC that Doug (DSB1829) is doing the same with the Ampmaster 3000. Here is the link.... http://www.reefcentral.com/vbulletin...threadid=46143

I have to disagree. Andy clearly states that they require 1800 GPH. I think that he would know better... He did make the skimmer after all...

Sort of to the point statement considering naser tells us nothing about the headloss, the amount of restriction or anything about what his intentions are. A am3000 can push well over 1800 gph as you should know. Without further information how do you know he wont be pushing that amount? Andy (myreef) tells him "Neil, You can do what you want." and refers him to a thread of simlar application.

I think Naser needs to tell us more about his application for any one to make any suggestions

[myreef]

What I really mean is that it really depends, as both of you said, how much flow you are getting to the skimmer. I personally do not like to run the same pump for different applications. I like redundancy, I think it is my computer background. Anyway, I have been asked this several times and I always say, yes it should work, but it depends on how you have it set up. Doug is the first person that I know, that has done tihs on one of my skimmers. I would contact him via email or that thread on RC to see how he has it set up exactly and how much flow is going to the skimmer Vs. the return. Someone has asked him that very question on RC right now, so you may just want to watch and see what his response is.

Although I do recommend 1800 GPH on the MR-2, I would not hesitate to put the Iwaki 55 or 70 on the skimmer, but they are pressure pumps with much less flow. HTH

[Ironreef]

MR2 = my question is isn't 1800gph alot? Or are you saying a mag18 that is 1800@0? I wonder cuz my Bullet2 =close to being the same. i use a mak4 for my skimmer teed off to my reactor and my refugium 5' away and i still need to open the gate all the way. So I wonder why the MR2 needs so much pump??? Just curious.

[myreef]

THere are a few differences in my skimmers Vs. The Bullett 2 that I feel can make the skimmer handle more power. I know that beckett skimmers can take a lot of horse power through them...in most cases the more you can put through it the better. Can you run a Mak4 or equivalent on my skimmers and have them perform well? Yes, but I feel if you really want the skimmer to perform at the utmost capacity, you will be better off using the MAG 18 or equivalent. A refugium and reactor don't take that much power out of a pump since they are such low flow. I think you could run the MAG 18 or Iwaki 55-70 and even have a better skimmer on your bullet. That is my recommendation....A MAG 12 will run well a MAG 18 will kick butt.

[golfish]

I wonder if an Amp Master will be able to push 1800 gal through a beckets head by itself.

Naser,
This is for your new tank? looks like you have two 3/4" Sea Swirls? You should be able to draw 1800+ gal per hour down your 1.5" bulkhead\drain, You'll probably need to run the AM3000 pretty close to full throttle to max out the two SS's...reducing the pipe size really reduces GPH, you probably wont be able to run both but like Andy says..."You can do what you want"

[Ironreef]

so you are talking mag18?The mak4 has more power reguardless or rating. i had a mag18 on my Bullet had to close the gate valve. put a mak4 and it blew the mag away. 1190 @4' mag 18@0 but mags don't handle near the pressure. I had to tee off the mak4 cuz it had to much power.And open the gate all the way. My refugium is @5' away and so is my reactor = that still takes away flow. My bullet i couldn't imagine performing better. the bubbles are tiny and thick white. An Iwaki55 will blow away a mag 24 . The ratings aren't =. pressure inline pumps has alot more power.I was just wondering is you used an inline presure rated pump or mag. Cuz iwaki55 would be alot of power or to much through my bullet. Even if the myreefskimmers can handle more power I couldn't imagine a 1800=Iwaki100 going through a 24" skimmer. Have you ever use an Iwaki55 through a MR2?? Just curious becketts like alot of pump but should need that much?? But like I said if your talking mag pumps I see the light. JME/JMO

[Ironreef]

I agree depending on your plumbing you may only get 1800gph that would be 900 for each seaswirl. Not much left for the skimmer. But what you can to is plumb the ampmaster to the skimmer. Put a tee on it so you can run another pump like the mag so= tee to skimmer from pumps. That way if the extra flow form the ampmaster isn't enough you still get more gph from the other pump. But I would just hook it up and see. Deson't matter what ppl say. You just need to do it and try.

[myreef]

I am pretty much talking MAG pumps since I was/am selling them also as package deals. I am thinking of buying an iwaki 55 or 70 for my modified MR-2, (it is a few inches taller) Are the MAK pumps specifically pressure pumps? I have never used a MAK pump at all. I have only used Iwaki and MAG's. I agree that the 55, 70, and 100 Iwaki pumps will outperform the MAG's on the skimmers, since they are all pressure rated. I think we are almost talking in circles, since the differences in pumps are attributed to pressure and non pressure applications. If a MAG 18 is sitting right next to one of my skimmers, it will only be pushing maybe 2 feet of head, so what are we looking at 1500-1600 GPH?

The few people that are running dedicated Ampmaster pumps on my skimmers have reduced the 1 1/2" outlet to 3/4" fairly quickly to allow a more pressure application. I have 3 people that I know of that are running the Ampmaster 3000 dedicated on my larger dual injected skimmers and they say they create a nasty cum up the tube and into the cup. I intend on running an Ampmaster 3000 as a dedicated skimmer pump on my upcoming 550 gallon project (2 years away, but planning now). I will have comparative rating for pumps soon as I intend on gathering information on the MAG 18 and the Iwaki pumps soon.

Gee... Tough croud! Can't you take a joke? I am disagreeing with the skimmer's maker. That should tell you something... :eek3: I think myreef would know better than me...

[Ironreef]

We all know your j/k I was just curious why they needed so much pump?? = mag really isn't much pump ime not like the ratings. MYREEF maybe right I wonder what a mak4 puts out at 2'? But mak4 is a powerful pressure pump. i was just wondering why my bullet didn't need that much pressure thats all

[myreef]

Its' not that they need that much GPH, but I like to put a lot of GPH on them if you are not running a pressure pump. You could get away with a MAG 12, but the 18 is much better. It is hard to compare pressure pumps to non pressure pumps, IMO. If pricing on pumps were all the same, I would put an Iwaki 55 or 70 on the standard MR-2 and a 100 on the dual injected.



PS--Yes, I knew you were kidding Mark!

[naser]

ok ok everyone calm down.. i t'd the pump off to the skimmer before the ball valve. that way all the full power goes directly to the skimmer. the 1.5 overflow can only handle so much so i then have to turn down the feed in turn giving the skimmer even more juice. its airating the water great. right now i have nothing but clean salt water. waiting on the live rock. 1800gph or not you can only fit so much through a 3/4 inch line. i appear to be acceaving this. oh golfish im using two 1 inch seaswirls on my new baby.

[ridetheducati]

Naser,

1800 gph going in.

How much is coming out?

Very curious.

This thread got me thinking a bit.

[naser]

well im thinking 1800 gph wouldnt fit through a 3/4 hole anyway. the only thing the skimmer is looking for is pressure. well thats what i think. theres no way i can run the ampmaster full throttle. my drain cant handle that flow. i have it about half throttle now and it kinds keeping up. the full pressure is being brought to the skimmer before the ball valve.

[ridetheducati]

I ask the input vs output question because a fellow reefer stated he was pushing roughly 1400 gph (head and friction loss calculated) and the output was 400 gph. He was wondering if his skimmer functioning optimally

Mag 18
Skimmer Bullet 2
Tank size 150g plus 150g sump= 300 gallons of water that needs processing


Skimmer is processing tank volume ONE time per hour. Is that enough??

I suppose the skimmate is fine, but can it be better. Like I told him, nothing is 100% efficient. Just get as close to it as possible.

[myreef]

The output of the skimmer vs the input is not tough to calculate. I did these calculations at one time, but have lost my notes. You can run a skimmer and let it drain into a 5 gallon bucket. Calculate how long it takes to fill the bucket then divide by seconds filled then multiply by 360.

So it would look like: 5 gallons filled/time to fill 5 gallons x 360.

The speed at which the skimmer will drain is in direct proportion to the gate size valve. A larger gate valve, the faster it will drain. I use 1 1/2" gate valves on my MR-2 and larger skimmers. HTH

If he has access or could borrow a mak4 or mag24 i would try that and see if it is better than what it is now.
