What this situation lacks is some real comparison, just thought I'd post this:
Have a look at this email I got from one of the guys off ultimate reef, he's done a test between a Deltec 703 Skimmer and an AquaMedic 5000 Twin.
This guy has a fairly large system and quite simply used just one skimmer at a time, then swapped from the AM to the Deltec. He repeated the test again to see if results we similar and, they were. I believe all variables (stock level, feeding, water etc) were kept as constant as is reasonably possible.
Interesting!
Hi Tony,
Just analysed the results of the two skimmers.
I have done this twice now to ensure that the skimmers were at their optimum performance.
AM 5000 Twin Test 1: 632ml
Deltec AP703 Test 1: 905ml
Am 5000 Twin Test 2: 640ml
Deltec AP703 Test 2: 907ml
I had the skimate checked at work - the Deltec AP703 skimate allowed 20% less light through than compared to the AP 5000. The results were averaged for over the two tests.
The AP703 skimate weighed just over 1.5% more than the AM 5000 - this is because there was more particulate in the Deltec skimate. The results were averaged for over the two tests.
So overall, you can see that
(1) the Deltec skimmer is some 50 better in the amount of skimate it collects
(2) There are more solids in the Deltec skimate (by some 1.5%). I think this because the amount of air the skimmer pulls in and
(3) the Deltec skimate is darker by 20%.
Finally, using the AM 5000 as the reference, one can summarise:
AM 5000 - 636ml Light = 0% Solids = 0%
Deltec AP703 - 906ml Light = -20% Solids =+1.5%
All in all the Deltec skimmer is much better, I think.
I would love to carry out a few more tests - but am short of time at present. Mighet get some more done in the summer - if that helps.
I am about to plumbe in the AP1006 soon.
I hope this helps.
Regards
