Hey Mojo, I'm very curious if you have experienced this with your skimmer's production or spoken with people that have.
First a little background relating to my question... I've been carbon dosing for going on a year now. I only dose with vodka and I also dose Brightwell Aquatics MB7. I find it quite amazing how well it works; I get hardly any microalgae on the glass, corals are healthier looking, I feed a good amount so the fish are fat and happy, and best of all I water change much less frequently. And the only reason I do a water change every 4 to 6 weeks is just because I feel some additives may be replenished through the salt, the nitrates and phosphates certainly don't need lowered. I do also run carbon and GFO through the media reactor.
Anyhow, to my skimmer related question...
It's been months since I've really seen the skimmer work all that much. I almost feel like with these bacteria driven systems that the skimmer is becoming less important. I have an ATB 1050A, have borrowed my buddy's 840 with the thought that the 1050 was too much, and the skimmer I replaced a few months ago was a Lifereef VS24. And none of them get much production, if any, no matter how much I work to dial it in. I have to dial in for a very wet skimmate to get just a small amount. I have a 125 DT, about 40 gallons of water in the sump, and a somewhat heavy fish load..... 17 fish of which 3 are tangs. And I feed about 5x/day... a mix of frozen, pellets, seaweed and flakes.
So, it would seem I would get some production based on my bio-load and feeding routine, but do these enhanced bacterial colonies so many of us now strive to obtain perhaps minimize the value of a skimmer?
