Jim, what about the effect of the black pinwheel on the sedra 5000?
thanks, Mike

The new impeller should help on the 5000, but I've never asked over at ER.

jc,

I bet the mesh would be sweet on that 3500.

Good to know. I've never modded anything on my skimmers, so I can only go by what others say in that dept. The mesh looks like it can help out, but only on the larger pumps I guess.

Cheers,

Jim

that is 60-120 lph. think of it in %. you can definitely get more.

You will have to get rid of that venturi to get the full benefit. The 3500 venturi is grossly oversized on the suction so the pressure drop is inadequate to pull max air.

that's a big maybe because the air meter jumps up and down so its a little hard to tell.

Anyone running a gate valve mod on a CS80? I recently built one but can't get it to work efficiently. In fact, it's overflowed a few times when I wasn't at home. I ended up putting back on the stock pipe and sponge system and it's working great. I'm wondering if I built it incorrectly. I don't have access to a camera at the moment but I will try and put up a pic.
I would appreciate it if someone would post a pic of a working modded CS80.

Thanks

Well, I'm really disappointed in the ER customer service that I had heard so much about. It took them over a month to get me my replacement impeller and it was just as noisy as the original. So I decided to say SCREW THEM!!! I got my hands on some of the mesh material that is used on the ATI bubble masters and I'm blown away. After I modified my impeller with the mesh fabric the results were amazing. I can't wait to see what the results are when I convert to a recirc next weekend! I'll post plenty of picturesl

Glad you have yours finally working. I'm interested to see how the RC mod goes.

I didn't get good results with the MW. I made 3 of them with the PF4 mesh, and none worked as well as the stock (new improved type) ER PW on my RS250. The MW pulled a little more air, but made a lot more noise, used a lot more power. The main problem was my skimming noticeably decreased. I'm back to the ER PW and its working much better.

I'll take some pics of the recirc mod when I do it this weekend. I'm going to drill the holes opposite the output tube like the RC skimmers have and use the current hole to supply. I haven't decided if I'm going to feed it from my overflow or use a MJ1200.

I know it's in the wrong forum (posted there too) but does anyone have a 1.25" gate valve mod. that is not being used that they are willing to sell? I recall someone ordered the wrong one & couldn't return it a while back. It's for a 5-3...hence the smaller diameter fitting.

Isn't that hole too low for a supply? It should be up near the top.

We recently got a RS180 as well. Still haven't been able to use it because it's so darn loud.....it drowns out the TV.........

Just out of curiosity - how loud is yours?

Why should the hole be near the top? The Recirc pumps are drawing the water from the bottom of the skimmer so I would imagine having the hole right in the middle of the chamber would be perfect placement. Does anybody know why the hole should be at the top? Or does it matter?

If I use the current hole for the recirc pump the skimmer will be off balance because the pump won't be mounted across from the output. Does that make sense?

Look at every recirc skimmer. Deltec, H&S, ER, Octopus, etc. They all have the feed at the top. The output of the skimmer is at the bottom. The feed flow comes in the top, goes out the bottom. I would plug the hole that is there now.

Anyone ever run a RS-100 with a sedra 5000?

sjm817,

I agree the feed should be lower. Having the feed at the top only serves to cause turbulence in the bubble column.

Then why does every mfgr (that I'm aware of) put it at the top? There must be a reason.

I do know that when I did my recirc mod on my ASM I used the stock hole for the feed and the performance still tripled. I'm goinf to e-mail EuroReef and see what they say.

Its an interesting point. If it was better on the bottom, you would think the skimmer mfgrs would build them that way.

Steve, do you have enough time on your RS180 in the non recirc mode to make a good before and after comparison?

I would think it is so that the skimmer does not drain back into the sump. I think a 90 on the inside to direct the incomming water to the bottom would help.
