I finally got my MSX300 broken in decently and its starting to create some excellant skimmate. Right now it is working in partnership with a Tunze Master DOC skimmer in a dual-skimmer sump set-up.

This skimmer is working very well and is able to pull out similar quality and quantity as the Tunze skimmer even though the Tunze cost double $ and has been broken in for several months. Not trying to compare the skimmers since the Tunze has certain very important advantages to me, most important being the anti-foaming feature among others.

Anyways, the first pic is of the skimmers doing work. The pics are about 5 hours after I cleaned the cups. These things are definately doing some serious work as you can see by the skimmate created in just a few short hours.

Second part of this thread is my question about adjust skimmers. I have many excellant skimmers working on my different tanks but even though I have so much comparative data I still find it difficult to figure this out for some reason. Where do you want the water level in a skimmer in general? High enough so that a very small foam head (or none at all if your daring) is created which would result in a lot of crap being tossed out into the collection cup or would it be better to have the water level low enough so that a significant foam head is created, thus creating that typical scene of foam down the sides of the collection cup?

Right now I have the Tunze (left side and also second pic) running lower which creates a nice foam head. As you can see the foam head gets dark with organics and then slowly spills over into the collection cup. You can even see a lot slowly oozing over the sides.

The skimmer on the right side (msx300) and also in the third pic is running water level higher which creates a very thin foam head since it gets pushed over into the cup before it creates a head.

So which is the better way to run a skimmer? Both ways the skimmate is nasty so at this point i am just trying to fine tune.

p.s. For all you MSX users, the silencers restrict quite a bit of air. If you take off the top part of the silencer (like you can see in the pic) it will allow the pumps to suck in air at their maximum potential. Its not a HUGE HUGE deal but it adds to the list of mods that can be done (like re-doing the mesh, replacing the air lines, etc.)

well, i personally prefer wet skimming to be sure, it's not nearly as impressive looking as dark skimmate, but because of the rate of collection, more nutrient is removed from the system as a whole.

and to try to answer your question...

i dont think there is a water level or a setting that is universally superior as far as all skimmers are concerned...
adjustment of skimmer level changes because of many factors, but primarily they would be;
the amount of time process water dwells in the skimmer,
the lph of air injection,
the design of the reaction chamber and collection cup of the skimmer,
feeding and dosing habits,
bioload.

so to me it's an issue that is addressed with every individual skimmer, and finding the "sweet spot" is really the ultimate goal.
also, obviously some skimmers simply work better than others, they are like italian shoes....you get what you pay for.
i appreciate your taste in skimmers....now go mesh mod that rubber tunze impellar and watch the sparks fly....
that would be a good skim off between the two then. :)
 
well, it would depend on what the contents of that tank were...
i usually do 500 lph per 100g of display tank for sps...

so each pump is 1200 lph of air @23 watts
so, a total of 2400 lph of air, 46 watts,
so i'd say 500g sps

I would say 300 would be near the top of a decently loaded tank that it could handle well.

Yea different things affect skimmer performance but thats not what I am trying to drive at. For the most part, are skimmers designed to build a foam head that slowly gathers organics and eventually spills over once it gets pushed up high enough in the riser tube by the underlying foam? Or are they designed to created tons of bubbles that organics stick to and we should try to get the bubbles themselves directly over into the cup without trying to create a foam? I suppose you can liken this to describing the difference between skimming dry and wet, but I think thats slightly different. That is more like asking how large and thick do you want your foam head before it spills over into the cup. The thicker the dryer your skimming, and vice versa. But I am questioning here if we really do need to create a foam head or of thats hindering performance in general in a skimmer instead of trying to get the bubbles to pop right over into the cup.

And I thought about doing a mesh mod to the tunze but the pumps are perfectly matched to that size body. The skimmer actually has no adjustments and is designed to never overflow. Its engineered quite well, and all the components are designed and work very well together that you can only appreciate if you get your hands on one. I don't think I can improve anything on it.
