9015 vs 9010

[FastUno]

I am trying to determine whether to go with 9015 or 9010. In a 90g moderately stocked tank.

I have read your posts where you recommend the 9010 for more wetter skimming. Your recommendation does not make sense to me based upon the 2 skimmer specs. I see that they have the same water throughput, air capacity, & pumps (based on 21W usage). Is the 9015 2" taller due to the collection cup? Does the 9015 have a larger body/water container & allows for more water to come into contact with air bubbles, which in turn leads to darker skimming?

Lets take a hypothetical situation. If skimmer A produces 100ml/day of dark skimmate & skimmer B produces 100ml/day of wetter skimmate, then I would be inclined to use skimmer A. Even if skimmer B produces something in the order of 150ml/day of wetter skimmate, I would still choose A. I can take that same dark 100ml of skimmer A & add another 150ml of tank water & it would look as if skimmer A produces 250ml/day of wet skimmate. Hope this makes sense?

Now lets say if skimmer B produces something like 1gal of wet skimmate/day, then I could understand how anyone would recommend skimmer B over A. How far off do the 2 skimmer fall from this type of situation?

Secondly, I am a firm believer that a skimmer's efficiency is also relative to where & how it's used in the tank. For instance if a skimmer is placed in a sump where it mixes with new water coming in from main tank & skimmed water, then it will not be as efficient. If the skimmer receives a constant supply of dirty water & the new water is redirected to the return, then this makes for more efficient skimming. How can I setup a 9015, lets say, to work this way?

They use the same pump- i.e. same water throuput, however, the air throughput stated is maximum and in no circumstance could you get the maximum on a 9010 without collecting just a cup of water. The 9015, allows for full throughput of air and thus increased performance. You should get the 9010, that is all you need for your tank size. On these skimmers the cup doubles as the foam chamber and in the 9015 both are 2" taller.

It really wouldn't be possible to set up the skimmer as you wish, it should be placed in the sump with a gentle flow by but the intake is on the same side as the output.
