Ereefic--

feeling rather stupid. I can't visualize how this would work. since I don't have experience with recirc skimmers maybe that's my problem. why doesn't the pump either push water up the display drainpipe or cause backpressure to the display drain?

I guess I cant see how you can have two non equal pressure inputs to the skimmer.

I bet when you post pictures it will make more sense to me.

So the drain from the display is going directly to the skimmer only to facilitate the dirtiest water from the tank?

I'm not sure how it works either, but it does. Here's some pics for ya. Let me know if you need some specific shots of anything.

The 2 drains are in the center.

Recirculation pump draws from the box and pumps into the dual becketts.

What about the MRC kalk reactor? is it true that the magnetic stirrer gets worn down VERY quickly b/c of poor design? Was thinking about picking on up ... anyone have experience w/ these?

 

[myreef]

RL....the stirrer does not get worn down quickly....we have sold extra stir bars about 5 times in the last year....so they arent wearing away.

Thank Eriffic. Proof positive that it works, but it doesn't seem like it should to me... I'm a non engineer type though. I'd love to hear from someone regarding how the pressure pump doesnt cause backpressure from the display draining into the same box.

I think I'd like to have it pre-drilled though. . . I'd love to have a bulkhead already in the skimmer instead of me hacking one in.

Ereefic-- I can't see how your output is configured from the skimmer. Can I bug you for a picture of that angle? I'm thinking about setting up my system much like you have done. Looks very promising.

thanks

Kevin

The output is just an elbow with the output above the water level in the sump.

I'm looking at the recirc skimmer and kinda stupid, but don't understand how the skimmers are actually fed the supply water??? I do understand how it's recirc, but not sure where it gets it water intially injected into the skimmer??? Thanks

There is a bulkhead between the 2 injectors on the top of the skimmer.

Andy should that bulkhead have been on top of the skimmer box?

They are on top of the box. Look at the pic a few posts above, you'll see it. The bulkhead for the recirculation loop is on the side of the box.

Yes, and it is.

 

[mungus]

Thanks for pics and the response ereefic. I gotta get me one of those!!!

[RGibson]

Andy did you send the E mail for that pump part? It would be good to be first with this.

 

[chriscobb]

Thanks Andy now it makes sense.

For the guy that started the MRC club WHAT is that kalk reactor doing back there.:lol:

 

[RGibson]

Ereefic-you need a Y fitting in place of the tee that ties the two Becketts together and you will increase the water flow to the Becketts by 30% and you can used a smaller pump if you would like to.

 

[NoSchwag]

A "Y" fitting and remove the 90's into the becketts.

Now that I had a chance to learn my skimmer, I put the old 90's back in and it was night and day.

Another night and day mod was the carbon air filter for the air in-take. It opened it up so much more and I never have to change the cotton.

 

[Ereefic]

Covey, yeah, I was waiting for someone to mention that.

After reading up on stir bar type reactors, I opted for a pump stirred instead. So far, very happy with it and it's of nice quality as well.

RGibson, are you talking a 'y' or a 'Y'? Andy, any thoughts on this?

 

[Ixthys]

I'd be interested to hear Andy's response as well.

If you have a strong enough pump, I don't see how it really matters if you have the tee and 90 degree turns or not.

 

[RGibson]

A Y pipe fitting. using a tee is like running water into a brick wall .A Y will give you so much better flow to each Beckett and more out put from the skimmer.

 

[Ixthys]

Still don't see why it matters IF you have a strong enough pump.
