Sorry about the paragraph thing. I understand. I am not expecting any of you guys to buy the ECO off of pure confidence. Carl did the tests that he felt he needed to bring this product to market. Nelson Herwig and I witnessed one of the tests in the zoo lab. Forgive the ensueing story because it will be quite hard to explain in words.
Imagine two acrylic tubes about 4" in diameter and 3' tall standing parallel to each other about 1' apart. These two tubes are connected near the top and the bottom by smaller acrylic tubes with a diameter of about 3/4". The left tube has a limewood airstone in it and a collection cup at the top, essentially a protein skimmer. The tube on the right is blacked out and has a small halogen light in a reflector mounted on top. This tube is connected with the "skimmer" on the left by the small tubes near top and bottom and the water is made to circulate between them using a small pump. Now imagine another set of tubes identical to this set-up but with an ECO-Aqualizer connecting the two tubes.
If you are still following me, a lux meter was placed under the bottom end of each of the blacked out tubes on the right. Saltwater was mixed with dark skimmate in a seperate container and then equal amounts were added to each set-up. LUX meters were synchronized with each other by rheostats on the lights. Next, the water pumps and air pumps were turned on to recirculate the water between the tubes and through the skimmers. Basically he had a light penetration test here. One set of tubes was circulated through an ECO and the other was a control.
Within twenty minutes, the one circulating through the ECO had double the LUX reading. Nelson and I tweaked it many ways. Skimmers on, skimmers off etc. but still it happened the same way every time. Then I compared a few parameters between the water in each chamber with a YSI model 800 handheld conductivity/dissolved oxygen meter. This was not a toy. Well....$1300 toy. The water that had been run through the ECO had a lower conductivity reading then the other and a bit more dissolved Oxygen.
Explanation for the lower conductivity? Conductivity is just that. The ability of the water to carry an electrical charge. Now saltwater is quite conductive because of all the dissolved minerals etc. but urine and metabolic wastes are also conductive. As the water that ran through the ECO exhibited greater removal of skimmate in the same alotted time, it stands to reason that the reduced conductivity was due to the removal of more metabolic wastes then the water that was not. The increased DO? I am not sure but I am sure Sam and Nelson have a better idea why.
A pH reading was taken with a Hach system. I can't remember the model but I used it everyday to take the daily readings for the 4,000 gallon reef system I took care of there. The pH was a few points higher in the ECO one after circulation for a little after an hour. Why? Sam has told me of a balancing between Hydrogen ions (+) which make the pH fall and Hydroxide (OH-) which makes the pH rise that is brought about by the negative forces emanting from North end polarity. Of course I know the relationship between these two pH factors (power of Hydrogen) but am still as of yet clear about how this could be brought about. I will ask Sam to clarify.
We wanted to bring this contraption to IMAC with us (and probably should have) but understand that while it was very functional, it was also not very proffesional looking. Plus we had no case for it and we were sure it would get smashed on the way to Chicago. If you have seen how they handle luggage in Midway you know what I mean. We were afraid that if we based our IMAC trip on this contraption and it got smashed.....what do we do now?
I am currently about to make a sturdier and more simple model using ten gallon tanks. Well, if you followed all that that was one test that I was privy to. A lot of testing was and is done by Sam Gamble. I will see if I am able to post some of that info or perhaps display it on our website. However, keep in mind guys, this is not my decision but I believe I can make a case for it.
Well....I have more to add but I am tired and want to go to sleep. I am not going anywhere if you guys are not either. I will stick with this until you all have considered all the info I can share fair. I don't know if any of you will agree with us or see it for what it is, but I promise to stick with this thread until you are satisfied with my due diligence....or you tell me to take a hike :lol: .
I will be very busy tomorrow and I don't know how much if at all I will be able to write but as I said, "I ain't goin nowhere"
Goodnight
