alright, maybe I could cut the top off, just below the blue, and fashion a square thumb screw flange set for it.

OR, if you go to a plumbing supply, you can get unions for larger diameter pipe up to 4". You toss out the pipe connector that isnt threaded, and use an acrylic disk to cap the union. Very easy to make, and you just use weldon or even PVC cement to attach the union to acrylic pipe...or even clear PVC pipe. I have made a few like this...much easier to make and use than a flange set.

hahnmeister

sounds interesting, but I am just not picturing it. Do you have a pic of one that you have made?? (I am a picture is worth a thousand words type of guy)

hahnmeister · #**229** 01/08/2006, 01:19 AM

Um, its in storage. Its a little late now, but tomorrow I will take a snapshot and post it. OR, I got the idea from the kalk reactors that the Barr and GEO.

Look at the plug at the top of the flange on this GEO. Its a small union, but instead of the other end of the union, a small acrylic disk is inserted.

I took some pics, look in my gallery.

got it now! Thanks for posting those.

Well, there are less expensive ones that seem to do the same thing. Anyone have one of these?

I know the Korallin if very popular in Germany
I don't have one. I hear from others that they do work, but the directions are hard to follow unless you speak Germen, which I don't very well.

That midwest Aquatic one...wow...that is a Korallin if you look at it...

reefguy888 · #**234** 01/13/2006, 08:50 AM

This one looks like the same thing too.

This is a pretty good review. I think they all pretty much do the same thing. Filter through sulfur and coral. Seems like a good DIY.

Where are all the tank pics of before and after?

Did it work??

I just ordered one this week from Rick @ Midwest Aquatics.

I'm posting in my local reef club forum as to updates on this particular unit and my experiences with it. You can find the thread here:
http://archive.reefcentral.com/forum...hreadid=752497

My tank params as of 1/16/2006:
Ph - 8.1-8.3(swing from night to day) measured with a milwaukee meter
Calcuim- 445.1-464.5 (measured with a Pinpoint calcuim meter)
Salinity - 1.0245 (measured with a pinpoint meter)
Alkalinity - 180 ppm (measured on a Hagen test kit)
Nitrites - 0 (measured on a Hagen test kit)
Nitrates - 30 (measured on a strip and also a seachem test kit)

I hope to have my unit in on Friday, 1/20/2006 and installed Saturday, 1/21/2006.

I will post full tank pics of before, during, and after the unit is installed and will try my best to keep my params updated to find out if the unit is working correctly.

The pics won't help much except I do have the remnants of a hair algae outbreak on my gravel now, so hopefully that will go away - which we'll be able to see in the pictures. Although I am fairly sure my outbreak was due to old RO/DI filters and they have since been replaced about a month ago. The hair algae has been dwindling since then, but the last small bit is stubborn.

any updates?

jnb · #**238** 02/06/2006, 12:20 PM

if you are referring to logman - go to the link he shows above - there a few of us who have recently put denitifiers on line

current=0-2ppm per Salifert

asmujica · #**240** 02/09/2006, 05:57 PM

Worst instructions ever!!!

Got it installed yesterday, even the picture on the back contradicts the instructions on media placement.

If possible I would recommend to fill it with the media when it already has some water in it in order to avoid trapped bubbles, even though they will eventually come out of the system. Who knows if you can accelerate the "break in" / "culture" by eliminating those bubbles from the start.

Or just plant a couple of mangroves in your sump that is what I did, Nitrates 0ppm

Sadly not everyone has got sufficient space to do that.

jnb · #**243** 02/10/2006, 11:33 AM

I wouldn't be too sad - using research, I can comfortably say that they are not that effective

Hence the amount of mangroves required and the space needed

Working faster than expected, Its nice to see algae just dissolve away. Every algae type is turning white and dissolving into the tank.

jnb · #**246** 02/16/2006, 07:21 PM

cool - what were and are your trates?

My trates kit is too old to measure

I am taking some before and after pics

Ereefic · #**248** 02/19/2006, 03:31 PM

How much will 1 litre of beads support? For a 375gal. tank, how much beads would you need if that tank has 50ppm NO3?

Avi · #**249** 02/27/2006, 12:32 PM

logman17....Can you update us on the progress?

asmujica · #**250** 03/07/2006, 04:07 PM

Well, I finally took the time to upload two pictures of what the melting looks like. It has continued to some degree but its getting harder to notice new algae melting occurances within the tank.
