Marc, when you went to MACNA I remember you talking about skimmers and their effectiveness. What I got from that was that most skimmers acted about the same regardless of price. Did I read that wrong and can you elaborate further?
That was a presentation by Scott Feldman, I think. Frank Marini attended it and was telling me how it would cause some controversy for sure. He gave me the recap of the presentation since I'd missed it, saying that the speaker indicated that most skimmers do the same job pulling out x% daily. He suggested that if you wanted to have better water quality, do a 10% water change weekly.
Since I didn't hear it first hand, I really can't refute or agree with the presentation itself. However, if what was told to me was accurate, I would disagree. Anyone doing a 10% water change weekly will have better water quality, because you are doing 40% per month. That has nothing to do with skimmers - that's simple math.
There are a lot of skimmers on the market. Do I think / believe they are equal? Heck no. There are better ones and there are worse ones, which most of us already know. The question that most of us would like answered is "Will that $5000 skimmer work better than this $800 skimmer?" We know they are made of acrylic, some plumbing fittings, and one or more pump. Does the injected air measurement matter, or are some simply seeking bragging rights?
I'm glad someone has endeavored to test various skimmers to compare their results. It's a very difficult test when you think of the logistics. Each skimmer should have the exact same load and conditions. Take my reef for example, and run a different skimmer for a month for 12 months. Let's say the first skimmer doesn't do the job well. The February skimmer might appear to be much better because it is not only pulling out the current load, but may be pulling out what January's skimmer could not. What if the tank has a small problem? What if the bioload changes? Or the food offered is changed? We really would have to do all we could to lock in the variables.
If I were to do such a study, I'd probably test six skimmers over a year's time. The first month I'd run my Euroreef. Then the next one the test skimmer. Then back to the Euroreef for the third month, then test skimmer #2. This would be a slow process, but at least each one would be tested against a standard. Should a water change be performed? If so, when? What if the tank has a spawning event? That's going to change water quality and indicate how the current skimmer is working.
This is the kind of test I would like to see performed because it is real. Having a skimmer clean up 100g of polluted water in a test system for a week isn't the same as what we as hobbyists observe daily.
Is your back feeling any better, Marc?
I've been trying to ignore it, but it's hurting a little more each day. I'm going to have to sit down with the chiropractor and see what he and I can agree with. It's only been about 10 days since my last treatment, so I don't think I got my money's worth at all.
Hey Marc, i know you have been busy with other things, but come on.. drop in and give us an update on the back and tank ect...
My last post was only a few days ago, Mr Byt.

The trip to Houston was productive, and Sunday was busy as well. I seem to be avoiding a cold that has been trying to pin me down.
The tank seems to be doing well. I'm still seeing slight losses in the LPS heads. I'd like to rip the pink hammer coral out and dip it in something just to see what the heck is eating them one by one, but I know the moment I disconnect it from where it has been anchored for years, I'll never get it back in that spot. The watch and wait thing isn't working too well though.
