Yep. It'll either be great or terrible. I'm expecting one or the other. lol

They are the 484x mazzei injectors.

Well if it turns out great, please let me know..

If it turns out terrible, don't bother :lol:

 

[hkgar]

The assumption being that flow rate is more important for air intake than is amount of flow, since you will be cutting the volume flowing past each venturi in half?

 

[jason2459]

I don't necessarily want more flow just more air. But this should give more flow and a lot more air then a single venturi.

This was my initial reasoning for going with the 484x

Can't help myself this skimmer is so awesome for being able to customize it. I'm thinking about making it into a dual mazzei venturi with 2 484x mazzei injectors. :wildone:

The 484x gets less water flow then the 584 but slightly more air draw. It isn't much less the air flow of the 684. I may even try it with a single one first at full 100% power and see what happens too.

[jason2459]

Don't know why I didn't think of this before. But I just got 26SCFH out of my 684 stock mazzei.

Removed the hose barb and little oring and slapped on a 1/2" vinyl hose. It is not a quite mod. Being in my basement that doesn't matter so much.

Interesting thread. It seems these injector style skimmers are coming back in style. I have two questions. First, has anyone heard what the manufacturer's reason is for not drawing the air from inside the collection cup like Lifereef does. I have heard it cuts down on cleaning out the venturi. Secondly, has anyone tried it on a Ecotech L1. They say they have a 21.5' head capability. I know they are more expensive, but they are DEAD quiet. Even compared to the Waveline. I do like the idea of having the 0-10v for hooking up to a controller though. Ecotech missed the ball on that one....

The way the collection cup is designed is totally different then most skimmer's. Usually there's a ring on the lid that forces the foam down right away. The life reef has that ring so the upper side mount of the air intake won't stuck in the skimmate foam. Usually that ring isn't that much wider then the neck opening up top.

The MTC doesn't have that lid ring. The foam pushes up and way out with no resistance which I think is a benefit in that there is no back pressure on the foam head like the typical skimmer lids would create when collecting inside the ring and pushing the foam down.

This is why there aren't any holes on top the lid either.


If the ecotech was apex controllable I would have gotten it.

Oh and keeping the venturi clear is easy. About once a week I boil a cup of RODI and shove the air intake tube into it to suck it all up. Ca1ore has his rigged up to automatically do something like that I believe.

Jason, Can you show me which part or end of the air tube line you use to suck up the boiling water to clean the venturi ?

Thanks,
Keith

Sure.

I get around a cup of rodi water and place it in the microwave for 1-2 minutes which brings the water to a rolling boil.

I bring that to the skimmer where I take the top of the air line opposite of the end that connects to the mazzei.


Air line pulls out and is shoved into the water which sucks it all up.

hey guys i have a question i have a MTC HSA1000

http://www.marinetechnical.com/page8.html

I wanted to know how to upgrade this thing and if there s a easier way to clean the top part where all the junk is without removing the neck up

I cant get a hold of the 2 brothers but was thinking to add this and what exactly are they suppose to help do


http://www.marinetechnical.com/page7.html

Did you get an answer on this from Jeff? I just spent the time cleaning my HSA1000 (that runs with an Iwaki MD-55RLT and is hands down the most awesome skimmer I have owned) that must have had a pound of brown gunk in it. There must be an easier way, however I have no more head room at all.

I am really liking the mvx 36 inch. I have an sro 8000 ext and a 300 gAllon display. I am reworking the sump and now need an insump skimmer. I run ozone on my skimmer and want to continue using ozone.

Can the MVx skimmer work with ozone? I know I can retrofit anozone intake into the Mazzei, but am wondering if there is a way to do it simply and if anyone has done it before.

 

[jason2459]

No need to modify the injector. Just need a T and a ball valve.

Below is how I have my ozone reactor setup. Just skip the CO2 scrubber part.

I had a question on my ozone setup and use. I've posted this before so most of this will be a copy paste.


You certainly don't need much ozone to produce results. I've also found very small amounts to help skimmer production while higher amounts hinder a good dense foam production. Some people will only run ozone for a couple hours right after lights on with great results.

I have used a 50mg/l redsea aquazone for years and have it down to running 25% for around 200 gallon system volume. That is a very small amount and poses little risk to fish even if GAC wasn't used. I do have a bag of GAC (ROX 0.8) sitting in front of my skimmer's output as a precaution. I do feel it acts like a flocculant at that small amount along with being an oxidizing agent. As others have said it's only one small part to maintaining my system.

More importantly though is that ozone isn't released into the atmosphere for you or anyone else in the house to breath in. (another reason I like very small amounts.) If using a skimmer as a reactor put bags of carbon over the collection cup if there's holes. I used to tape the holes up with duct tape except one of them and shoved my skimmer's airline in it to draw in any excess ozone air back into the skimmer. Lifereef skimmer do this already. My current skimmer is sealed on top with no holes so I don't have to worry about that part (MTC MVX).

Waterkeeper pointed me to these articles a few moons ago and should be read by anyone looking to use ozone.

Posted this just recently but shows how I used to duct tape the holes on top except one to suck back into the skimmer any unused ozone.

The MTC MVX is sealed with a rubber gasket and screwed down. No holes on top.

Now for how I have it all setup airline wise.

I use a T to split off and control freshair flow and airflow from the ozone generator. And you'll see I also use a CO2 scrubber pre ozone generator.

The sodalime CO2 scrubber actually does two things for me. It acts to reduce CO2 going into the skimmer which helps elevate my tanks pH slightly but it also drys the air some as well which makes the ozone generator more efficient.

I T off the air flow going through both the CO2 scrubber and ozone generator as the generator doesn't need that much flow and would actually restrict airflow if I didn't T off and restricting the air flow through the scrubber increases its life as the sodalime would be exhausted much faster if pulling 100% of the air draw through it and I found it doesn't help increase pH that much more doing so.

So
Air in > scrubber > generator > T > skimmer
Air in > T > skimmer.

If that wasn't confusing here's a picture of the airlines which may or may not help clear that up. And you'll love my way of connecting some of these hoses...shoving one into another. Im not concerned with airtight as the air flow through the generator is less then the total airflow.

Air in

Sceubber to generator

Generator to T

Air in to T and T to skimmer

And my ozone generator is controlled by my apex. Monitoring orp should be done when using ozone.

Fallback OFF
If DT_ORP < 400 Then ON
If DT_ORP > 425 Then OFF
If Outlet skimmer_7_5 = OFF Then OFF

Jason, I talked to Jeff about sucking up boiling rodi water to clean out the mazzel, and he suggested just to stick the air line into the sump to suck up some water, and that should do the trick...

It might but I'd be concerned with salt build up in the line

 

[goreef170]

Thats true, I'll probably do the sump every week then once a month the boiling water....:beer:

 

[ca1ore]

My automatic venturi cleaner uses water from the sump and I get no salt buildup in the line.

Water will leak out of the threads when the skimmer is off. Doesn't matter if in the sump, but a problem if external.

Yep, absolutely. I have mine internal.

I've been wanting to get this setup at some point still. I was planning rodi with it though. I know you've had this setup for sometime so now I'm curious enough to run some tests (long term) with my air flow meter.

How often do you run this again?
