Interesting observation

[Nanook]

My skimmer pump broke on me and it took a couple weeks to get the part. My polyp extension on the SPS is noticeably better after just six hours back on. Several stonies that looked kind of puny, are all of a sudden looking great...wonder if the increase in oxygenation really does that much??? Either way, this is a big difference.

Thats interesting,I guess it's more important than we think.

It's believed by many that the oxygenation of the water helps coral expel any contamination and waste.

See my theory is this. We all now that corals use chemical warfare. I believe that a good skimmer helps pull these out of the water. The more chemical warfare in the tank. The less polyps want to open. The less chemical warfare the more polyps feel safe and extend. This information is entirely based on no facts and personal opinion so it should be pretty solid.:hmm4:

What about those skimmerless systems that are growing sps like weeds?

Very low bioload most likely, or really good oxygenation through the sump. Dunno, the polyp extension after two weeks skimmerless was very noticeable, the corals looked a LOT better overall.

I don't trust those until someone explains exactly what they are doing.

We know it's a very low bioload

Monthly water changes is all I know of


I'm not knocking skimmers I run one myself, and I believe mine is considered a good one. I've got a heavy bioload
When my skimmer pump broke I seen my sps decline, now the pumps been replaced my sps are coloring back up polyp extension is better.

Personally I think that most people tend to over skim their tanks and reduce the amount of food in the water rather than just the nitrates and phosphates. I believe that most skimmer-less systems use some sort of nutrient export method that allows them to have an environment with lots of food but maintains healthy levels of nitrates and phosphates. Many nutrient export methods do oxygenate the water as well, like an ATS or refugium.

I think that in this situation you ran skimmer-less allowing the DOC's to build up but the O2 level dropped. Once you plugged the skimmer back in, the O2 level went back up but the DOC's were not immediately removed. So the corals had high O2 and high DOC's making them very happy.

Maybe it was because of angelfish Nook nipping and fragging corals before the holiday party? Tank has recovered from all of the hurricane Nook destruction. Maybe the D'Smacked angel has perished? No more nippers. It never was a pretty fish, with the torn fins from living in damsel fish hell.

You know me well. Skimmerless sense 2007. Skimmerless on my 93. I filter my water with an algae scrubbing frag tank. Box of rocks with good flow of a sump. Plus I have low bioload. Except that Vlamingi. It might not be able to spin around fast much longer to tag the scopas. That tang frags more corals than Smack starring at my tank. Still can't keep the water in that tank with that thing.

maybe its the clams.

About time you chimed in rams. Don't be bashing the angel fish. I had other plans for it, but at the end of that night plans were changed lol

You should be posting pics around here more.
Beautiful tank.
Beautiful Shots.

That's what I keep telling him. But no he's stingy like that :crazy1:
