MTC skimmer club!

It's not standard as far as I am aware. I custom ordered it as a 72" but he had slightly longer tube on hand and I said make it as tall as you can. I've often thought of upgrading the pump to an Iwaki MD55RLT. I think the tall body could handle a bit more.

Lovely dry foam

Just the couple couple extra scfh of air draw is producing a noticeable thicker amount of air in the skimmer.

If you saw the video embedded previously here's a comparison of the air filling in more of the skimmer and into the bottom of it

 

[jason2459]

Sorry, I told you all this thread needed more pics hope no one minds. lol

For anyone more familiar with LPM or LPH vs scfh here's a conversion chart

So for comparison

A SRO 3000 I had pulled around 42 scfh or ~1189LPH

Aquamaxx EM300 ~38scfh or 1076 LPH

Mag18 w/ 684 stock mazzei 12scfh or 339LPH

Mag18 w/ 784 mazzei 14scfh or 396LPH

Quite the difference in air flow yet similar or better skimmate production.

I just got done doing this

The waveline dc12000 is ready to go for next week.

1.25" FTP to 1" slip.
1" Spaflex pvc to a spears union. I like they are a bit more compact in size.
1" slip to 3/4" MTP
3/4" FTP/Slip elbow
Then the rest is all 3/4" setup just like the stock setup.

I found I had all the parts. (I have WAY to much "stuff" sitting on shelves collected over the years)

And this allows for 0 need for any clamps. Unions allow for easy disassembly and maintenance. That spaflex is going to keep shape a heck of a lot better too. I notice that vinyl tubing kind of narrowing in spots. I was hoping the braided kind would keep shape better.

The waveline came with two of these little washers like you have on a garden hose and it fit right in that 1 1/4" FTP side so slid it in there. Between that and the tape it should be more then good enough for in sump use.

Here's mine ...

I've got an idle PW150 that I've thought about using on the taller body, but I figure a larger injector is likely also required and been too lazy to do it.

Seems a bit wetter 2nd day in with the 784 mazzei.

And producing a bit more due to that

I'll clean it out timorrow night try and tune it a bit dryer.

 

[jason2459]

That bit more seems to have stall or at least slowed down a bit. Could be many things. Looked back and looks like I let it go a few more days for a week before cleaning it out and got to 1 gallon. So, we'll see what its like Sunday night.

3 days with
784 mazzei @14scfh
Mag18 @ 65watts

Previously
3 days with
684 mazzei @ 12scfh
Mag18 @ 62watts

 

[jason2459]

This skimmer is very interesting.

Its pulling more air @ 14scfh

Its pushing more water as indicated by higher air draw and higher watts used that correlates with lower head pressure allowing more water flow.
@ still averaging just over 65 watts

It seems to be running a bit wetter. Which all together especially the wetter part you would, or at least I would, think it would produce more skimmate. It hasn't.


After a week it looks the same.

But slightly under the 1 gallon mark

So, sencing running wetter is producing less I turned the nob down a bit and see if running a bit dryer and match the dryer production of the stock 684 with the installed 784 mazzei.

I cleaned out the collection cup and ran the pump in the davy jones to dump put the skimmate. I'll check back again in 3 days. After that I think its waveline dc12000 time.

great write up, love all the pics but dang you need to get an auto neck cleaner lol

Ha! Thanks. I've actually got an avast swabbie but decided to wait until I get through trying out different pumps and mazzei injectors first.

 

[ksed]

Great work Jason

 

[jason2459]

Great work Jason

Thanks

 

[jason2459]

Not much difference in the skimmate output with the mag18 and 784 Mazzei. Slightly more then the first 3 and second 3 days. Slightly less then the mag18 and 684 Mazzei.

 

[jason2459]

And now for something completely different...

I got the waveline dc12000 with the stock 684 mazzei installed tonight. I'm using the waveline controller for this too. I can hook it up to the apex but I'll do that later. The waveline controller has 12 speed settings so that will be more then enough to test with for now.

Pics with the all new plumbing and fully modular now with unions and 1" spaflex. Detailed the fittings earlier in this thread.

I tried out all 12 settings quickly and took some video at each level. Needless to say I was pretty surprised at the initial air draw at even the first speed setting.

I'll get that video uploaded and I will have to refer to it as well for the air draw numbers. But I do remember at the lowest settings it was already pulling 10scfh but water level/flow was very low. By the highest setting the water level was overflowing the collection cup.

What was interesting was the little to no difference in air draw once past level 8 I believe it was. Maxing out around that 20scfh of air draw. Very promising I think. Then will slightly lower flow at a slightly lower setting perform better then all out power on.

Right now I've left it to run for a starting point at level 8 and it's pulling about 18scfh of air. I left it with the water level right at the flange again.

Will update more with initial air draw numbers at different levels later.

 

[jason2459]

It's looking great so far

 

[ksed]

Very interesting Jason. Are you able to post the wattage?

 

[jason2459]

Very interesting Jason. Are you able to post the wattage?

Yep, I certainly will tonight. I am letting it run at least 24 hours to get the average watts used.

Run through with all 12 settings. Notes added to say what level it's at
