Quality Control & Controlled Experiment
Quality Control & Controlled Experiment
The prevailing hypothesis is that the quality control on the Remora skimmers is variable. Some Remora units collect more, others collect less.
Some Remora owners find that the depth of the clean-out screw has an impact on skimming. Some Remora owners (and AquaC) find no significance in the depth of the clean-out screw.
My experience happens to match the AquaC "Two weeks of collection" webpage (
http://www.proteinskimmer.com/products/Remora.htm). The bio-load in my system was not the limiting factor. I replaced my Remora (MJ-1200 + surface box) with a Tunze 9010. The Tunze has been collecting a full cup (200ml-300 ml) daily and has visibly enhanced my water quality. I consider my experience to be a controlled experiment: same system and same initial parameters.
One way to evaluate a skimmer is to replace it and see if the second skimmer produces better results. If the results are equal, one can claim that the bio-load was the limiting factor. If the results are different, then one of the skimmers was the limiting factor.
Another way to estimate skimmer performance is to listen to the manufacturer. According to AquaC (
http://www.proteinskimmer.com/specs.htm), the Remoras are meant for the following size tanks:
Remora (20g - 75g)
Remora Pro (40g - 125g)
The 1st figure in each pair represents a "heavy" bio-load. The 2nd figure represents a "light" bioload. A buyer should give greater weight to the first figure.
I called AquaC about my 75 gallon tank. AquaC told me that my Remora was undersized for my system. I upgraded because of AquaC's candor.
