mag 24as a return/ cpr cs102 overflowbox???

[pangetikaw]

hey guys i was wondering if you guys can give me you guys input on having a mag 24 as a return and hook it up on a 1' scwd and may be some reactors?? what do guys think is this pump to powerful?? would it drain my sump ?? i have a 140g display and 55g for my sump and ill be using an overflow box from cpr which is the cs 102 which is rated for 1200g. Do i need to get a bigger overflow too or what not????? uhmm head preasure its 5'ft tall thanks a lot guys



thanks for the advice

I would stay away from the CPR boxes and go with a U tube design. The U tubes are less prone to failure as long as you have enough flow from the return pump. Go with either 2 boxes or a single that has the GPH you are looking for.

Agree stay away from the CPR. Get a U Tube overflow or better yet, drill the tank (its not hard). I would not use the Mag24 or a SCWD. Sorry to give a negative response on all of what you asked, but better now than later.

 

[pangetikaw]

cool deal thats why im here to ask and get some advice and opinions on you guys. why not mag 24 and a scwd? if you dont mind me asking. is cpr that bad just wondering thanks alot for you guys opinions.

 

[sjm817]

CPR - unreliable design
Mag24- too big/hot/noisy
SCWD - very flow restrictive, failure prone

 

[shleprock30]

The CPR relies on a external pump to keep air out of the siphon, it is very easy for that hole to get plugged up and your siphon to break, which in turn leads to a flood.

This is where the least point of failure is the best option, drill, then U tube, then...................CPR

I would agree to drill if you have that option, but I have never had a U tube fail.

ohh i see.. so how about if hook up an float switch in the overflow box and hook up the aqualifter to the switch what do you think of that? is this possible ???


scott
what pump do you suggest my space is very limited and they say that external pump is loud any in sump pump you can suggest ??

 

[sjm817]

Dont use the CPR. The float switch is a band aid on a band aid. There are much better options. DRILL IT! DRILL IT! DRILL IT! It is very easy to do. You can get a kit with everything you need including the glass hole saw from http://glass-holes.com They even have a video that shows you how to do it.

If you use a HOB overflow, I highly recommend one from Lifereef This is a very reliable overflow.

For a pump, there are quiet and noisy internal and externals. What is your preference?

 

[pangetikaw]

so what pump do you guys suggest

 

[pangetikaw]

ill say internal pump coz of the space limitation

 

[sjm817]

I'd use an Eheim 1262.

eheim pumps are whisper quiet, simply put they rock.
I have a mag 24 on my 210 now as my return pump until the tank goes into the wall this summer and its been on for ~2-3 years now, the mag drive pumps run flawless in my experience with them. They are not quiet pumps but they perform well, its not that bad otherwise my wife would have had a fit.
I have not had any heat issues, i would not say they are too big for what they are, i have seen way bigger designs on pumps of equal gph.
do yourself a favor and drill the tank and install something along the lines of a durso pipe, way better than an external overflow.
My 210 was the 1st tank i have had with built in overflows and they are great, I wont ever purchase another display tank without them.
Frag tank is different, dont need anything fancy for those.

 

[pangetikaw]

thanks for the inputs but i think my tank is not AGA i think its tempered im not really sure about it you so... i dont want to take the risk of drilling it. but i know its going to be a lot better if my tank is drilled i wish i can....uhmm so you think this mag 24 is good for the size of my aquarium and sump??? i was thinking of hooking up a scwd or at least give it a try?!? or i can diy close loop??? they said its too powerful that it might or will drain my sump??>>

 

[sjm817]

When I said the Mag24 is too big, I didn't mean physically. It has too much flow. Even so, the typical aquarium plumbing setup will drastically cut back the flow anyway. You wind up with a high flow pump and low flow plumbing. Typically, you want ~ 3 - 5x display size for return flow. 420 - 700 GPH for a 140G. The 1262 would be up at the 5x end of that.

The tank is likely just tempered on the bottom. The back panel is what you would drill. If you go HOB, get the Lifereef. After your first flood with the CPR, you'll wish you did.

 

[shleprock30]

Scott is right on target here, definitely good advice.

 

[pangetikaw]

thank you will go check out lifereef overflow and eheim pump hey should i get the 1200 overflow or smaller overflow

 

[sjm817]

I think you will need the double. The 1262 with typical plumbing should be around 700 GPH which is too much for the single overflow. You could get the single and put a valve on the output of the pump and throttle it back. You could also get a single and the 1260 pump instead. It would be more @ the 450 GPH 3x end.

 

[pangetikaw]

yeah... your right i will check lifereef! what do you think of the quite one pumps??? just a taught about it

 

[Toddrtrex]

I have to agree with everything that Scott (( sjm817 )) has said. While the lifereef is more expensive then other U-tube HOB overflows, it is well worth the money (( if drilling isn't an option )). I have one (( single )) on my 75, and in 6+ years of operation it has never given me an issue. Also agree that 700 GPH would be too much for a single, I have a 650 GPH (( before headloss )) external pump, that I had to throttle back.

As for quiet one pumps, I have never used, so can't comment.

Quiet One pumps are low head and Mag Drives are high head. Where this makes a difference is in the efficiency. Quiet One pumps up to the 4000 will put less heat into the water vs. the Mag Drives.
