Got my new CS1000+ Skimmer up and running!

Got my new CS1000+ Skimmer up and running!

Check out this Euro-Reef skimmer now running on my 1200gal SPS coral farm!

It's a modified/beefed up RC1000 built by Euro-Reef. It Stands 56" tall, has a 1 1/2" inlet, 2" outlet and uses 7 EHIEM NW pumps! Fits like a glove.:thumbsup: They fallowed my space requirements to a tee and were able to also add an extra 4" to the reaction chamber and another 4" to the riser tube. I added another 5" to out-flow tube to get the water level into the riser tube, and I also added a little mesh modification to each impeller to make the bubbles even smaller.

Here is a shot 16hr later

This is what I used to get in a week with the old DIY skimmer!
This was with just 4 of the 7 pumps running over night!

I ended up undoing my out-flow extension, lowering back to where it was and tested it with all 7 pumps. Here is what that looked like.

and looking at the bottom skimmer from another angle

Very impressive!

That's a nice little piece of equipment there!

 

[hahnmeister]

Wow, looks like it actually be running better with only 4 pumps rather than all 7! What a beast... I think that is the largest ER I have ever seen.

 

[hoyta]

That things is super nice I'm going to be doing a mod like that very soon!

Steve1714,
Before I hack up my ER impeller to do a mesh mod, could you elaborate on the procedure/type of mesh you used and how you feel about the difference it made?
That looks fairly simple and best of all doesn't destroy the impeller, I'd like to see how it will work on my system.

Thanks, Chris

A sea K,
All you need is some mesh that has smaller holes than the pins, this mesh must stretch, not peal or tear apart, the stuff i used i think came from a bag of marbles. Look around the supermarket next time you are there and you will find this mesh used to hold fruit and stuff. Just get a few layers pushed through the pins, i only used 3 i feel if i did 5 it would be too much for the chamber to handle, I've gone up to 5 and six layers on the Sedra pumps with positive results. It's as simple as it looks in the pictures, and if you don't like it later just take it out. Just be careful not to loose those spacers behind and in front of the impeller.

here is a close up.

Steve,
I have an RS 80 Euro-Reef, would this mod work? After modification do you still use the spacers?
Thanks

I would think that these skimmers (to a degree) are designed to handle a certain amount of air. By modding a pump to draw more air, you may or may not cause too much turbulance in the skimmer body and neck. This can cause lower productivity.

I'd really like to hear from euroreef tech1 on this. I know on some of the older sedra models, the extra air is okay in the body, becuase the pumps were underpowerd. But the newer ER's match the pump to the body much better than they did in the past.

My RS80 is less than a year old.

I've posted this before, but I had an RS250 (SP5 pump) that I did a mesh mod on. The LPM increased from 18 to 20. It used a lot more power, made a lot more noise, and I could not get the same production as the stock ER PW impeller. This was a typical 3 layer PF4 mesh type impeller, not mesh added to the PW impeller.

 

[bozack]

does upgrading the ER's that come with the Sedra 5000 to a 9000 make a noticeable difference?

Or it is similiar to just modding the 5000?

 

[shag26272]

I did the meshmod on my RS80. I cut the little stubs off the impeller so it was flat and used Enkamat PF4 that I bought on ebay for 5 bucks. I used 4 layers with 2 small zip ties that go through holes I drilled in the plastic. You still need the spacers. My skimmer is performing about 25% better at least.

Can someone tell me the ID of the restrction on the intake venturi for the eheim 1262's?

^^^ does anybody know?

I could tell you..... but then I'd have to kill you......

 

[shag26272]

It would be nice when people asked questions about upgrading pumps and such that everyone could see the answer instead of just a PM. Just an idea.

Or I pay $48 SPE5 Volute & Venturi Combo.

jtravis2,
this modification should work on any and all needle wheel pumps, you do need to place the spacers back in like they were originally so it works properly. I cannot say this method will suck in more air but i can say the bubbles are smaller. There fore if the bubbles are smaller and the intake of air remains the same this means you just increased the available surface area for proteins to stick to and this would make the skimmer skim better/more. I don't recommend chopping the pins and mounting the mesh because you won't be able to balance it correctly and it will wobble and this will cause the impeller to wear incorrectly and eventually stop working. For example; If you have ever installed a new tire on your car and forgot to get it balanced you would feel it wobble, same goes for these impellers, if not properly balanced it will destroy itself and possibly the inside of the pump as well.

No offense but all of the effective meshmods I have seen have taken off the pins.

Steve,
I'm with you on trying to achieve a smaller bubble and that is why I'm interested in the info. I think your headed in the right direction and I appreciate the info.
I'll give this a try as soon as I have some time but will have to wait for now as my life in general is pretty frantic at the moment.

Hahn,
If mine wasnt glued to the pump I'd pull it and get your info but I cant. Sorry.
I do have a ER venturi off a Sedra but my guess is you already know that info and want to see if the Eheim venturi is different.
