Thoughts on over skimming

put out of action for eight hours a day, for example.
The missed protein skimming action is caught up
almost after the unit has been switched on again.
The Comline DOC skimmer has the advantageous
property of not changing its setting when switched
off. In this mode of operation, the skimmer should
not be run at the lower limit of the recommended
output for the aquarium."

Might just be propaganda, but it seems to say if you shut the skimmer off for a while (8hrs) then whatever skimming was missed, will be caught up.

Thanks for the info, kinda what I figured.

Just a thought but, I noticed in your pic that you have a relatively large leather mixed in there....I noticed quite an improvement will all my remaining corals after I removed all my leathers (xenia and toadstool) and started running a carbon reactor....I wouldnt think of doing a mixed reef without running carbon to help absorb any toxins that may be being released. Im not positive if the improvement was due to an increase in available nutrients or a decrease in "chemical warfare"

The pic in this thread is a previous setup, I just used it as an example to show healthy LPS in high nutrients. I don't currently have any leather corals or much for soft corals at all. I'm going to start thinking about building a sump soon so I can filter the water properly including carbon.

Haha come one, it's all about the gum ball effect, every bit of insight helps and is appreciated.

Out of curiousty, hows your skimmer running? Is it still producing a nice thick head of foam? Typically when you reach the point of over skimming the skimmer tends to produce less and less and can no longer maintain a thick head of foam and more or less starts to fizz. Fizz is the best way I can describe it.

I had the same issues with my BM250 on my 90 gallon. I started running it with one pump instead of two and it seemed to settle in.

It's off and on, sometimes it's foamy and sometimes it's just "fizzing". By fizzing I mean the water level in the skimmer is the same but there is no foam build up in the neck, rather the air bubbles just fizz about an inch or two above the water level. It takes a few weeks to a month to full the collection cup, on my previous setup it would only take a week.

By similar problems do you mean just the fizzing or problems with corals as well?
