Euro-Reef Eheim NW Thread

I don't see why not. It won't be cheap, but it should work well. If you do so, I'd love to see some pics.

Cheers,

Jim
 
Hey guys, I will be selling my ER Eheim 1262. I have a new impeller on the way from ER.

I am selling this because the Eheim 1260 Cerreta mod I built has been on and in use without a hiccup since my last posting of the side by side water throughput test. It has proven itself to me and I do not need the ER version.

The Ehiem 1260 I have has the orginigal ER PW in it now, that is why I ordered a new one. I tried to make the GG mod wheel and mesh wheel mod, but I did not like either of them. Nothing worked as well as the ER PW.

So, you can find the pump FS in the proper forum. I will link it when available.
Cheers
 
I purchased the Deltec AP701 today and will perform a comprehensive review in a heads up comparison against the Euro-Reef RC180.

This review will be detailed in scientific format as my other product reviews. The methods will be outlined and results will be objective. Then a discussion section will convey my experiences with the testing, observations, and any problems I run across which may have skewed the results or favored one product over the other.


In brief, the review will compare physical attributes, materials used, construction, cost, power and current consumption, air draw wide open vs. air draw at peak performance etc.

It should be noted that I was not going to buy the Deltec today for a lack how to measure the quality of skimmate. Then Skip came up with a brilliant idea. The skimmate after collection can be dehydrated and the organic residue left behind can be weighed. This along with measuring the quantity collected in a measuring beaker should provide information necessary to determine quality of skimmate produced.

I am still looking for some ideas on how to measure and compare quality of skimmate. If you have any other thoughts of how to do this, please send me a PM. The new thread will be posted in the DIY forum. I will post a link here when it is complete.

Thanks for your help today Skip.
Cheers
 
This should be very interesting.

You dropped a ton of $$$$ just for a test:eek::eek:

BTW, your pm box is full.

box clean.

Yeah, man exactly! I am in a bit of ahh too about spending $1216 to perform a test. However, I think of it as therapy. Katherine is in Africa working on a research program for HIV/AIDS transmission from mother to baby. I really miss her. :sad1: This hobby keeps me occupied.

I have doubled my thread posts on RC since she left iin July.
 
first off i just wanted to say great thred to everyone who contributed.

i have a turboflotor skimmer, pretty terrible, but i've modded it enough to make it acceptable for now. i am running a eheim 1260 on it and was thinking about getting this new impeller/pinwheel. i checked ER website but did not find the part. does anyone know where i can order it?
 
hey, is that a 1260 water pump version, or a 1260 with the special volute? Did you read in the thread where the 1260 WPV will not work with that standard volute?

I wonder if you can use light some how to test the transparency of the skimmate, assuming darker is concentrated/better. Light is one of the easier things to measure on the other side of the collection cup.

Edit: doh, just noticed the PM comment.
 
Rich, I think you are talking about using basic spectroscopy here. It will give the % transparency of a sloution. I have considered it and may do this, but I'm not sure it is necessary. It would be a guage to measure the wet vs dark skimming.

However, if one skimmer produces more skimmate by volume, but after dehydration the measured weight is less, then wouldn't I be able to claim that this skimmer was running wet compared to the other and the end result would be that it removed less particulate matter by weight?

What do you think? I like the idea, but would have to rely on outside sources to measure the product and I can not vouch for accuracy or the methods employed. If the above former information is a valid means of measuring skimmate matter then spectroscopy is not necessary. My only concern is that if some organics dissolve or evaporate in the process of dehydration, then this may effect weights and spectroscopy now becomes necessary.
 
Wouldn't a dehydrated wet skim have more solids than a dehydrated dry skim because of the salt content? Is there a way to account for that?

An RS180 would be interesting to throw in the mix to see how a non-recirc compares.

Good point here. I think you could be right. I'm not sure that spectrometery will catch this either. So, I am planning to run each skimmer to its optimal performance to pull a semi-dry foam as I have always prefered to collect. Then, test that.

RC 500

Here are the first pics of my RC500 It has been running a week or so. It is set up in a temp sump beside my stand. I cleaned the collection cup this morning so I can post some progress pics. So far I love it. It is skimming pretty wet, I've never seen so many solids skimmed out before.

didnt read through the whole thread but after seeing pics of the venturi i see the problem. most all ppl make venturis like that i i feel they are freaking dumb for making them like that. when you build a venturi you want the air inlet inbetween the inlet of the pump and the restriction of the venturi part. this way when the pump see's the restriction it pulls in air to compensate for the difference. most all mfg make the venturi like the one in the picture. i tested the one from gen x, looks just like the ER one, it pulled half the air that a simple venturi that i made using the ball valve method. i did all my calcs with a flow meter. btw i did got my gen x 2400 to pull 10lpm @ 20w

ahenson - "Skimmate of the Day" thread is hungry for a new submission - I'm sure that by tomorrow morning, you will have a nice pic opportunity....
