Skimmer skimming too little?

Hi,

I have a 100l/26g tank. It has a AquaC nano remora skimmer with a Maxi-Jet 900 pump set up in the sump. The amount of foam it produces is very variable, and sometimes it can go for a day or two at a time without producing any foam. The collection cup fills up to about one third after a month of use.

Is my skimmer underperforming? Any reason to worry?

How long has this tank been set up? What is the bio load in the tank? How much do you feed what is in the tank? All of these will contribute to what the skimmer pulls out of the water....if there is very little DOC in the water then there will be very little "foam" produced. Also do you put anything in the water like stress coat? These kinds of things will cause a skimmer to go nuts and not work properly. Please take a few moments and update your "my info" so we can better help you out.

Thanks

Perhaps I'm blind, but I can't find where to edit "myinfo" for my account.

I'll just fill in what you asked for here in the meantime:

- Tank has been up 6 months
- Inhabitants: Yellow-tailed blue damsel, Clark's Angel, Green Okinawa Goby, Coral banded shrimp, 2 blue-legged hermits, 2 other hermits, 5 snails, 2 feather dusters, a cool little urchin hitchhiker and a shy hitchhiker crab
- Water changes: Weekly 5 liter (total capacity about 100 l). Red sea salt, use tap water.

Water parameters have been stable, NO3 has been up and down a bit, but is at around 10 ppm now. Had problems with diatoms the first few months, but nothing now.

I feed twice a day. I try to feed sparingly, but I'm not sure if I succeed
I don't use any medication, the only additive I use is chlorine-remover for top-off water and new SW.

I run constantly with active carbon that I change every so often. The last couple of months
I have also used poly filter in an effort to get the NO3 down. Oh, and I have normal fluorescent lights, the tube says 10.000K, but I'm not sure if I can trust that

Since you only have 3 fish in teh tank I would suggest feeding once every other day. Feeding that often can cause problems for your water. How much LR do you have in the tank? Have you adjusted the amount of air that is going into the skimmer? I know that sometimes with a venturi type skimmer with maxi-jet you have to play with the amount of air to get it fine tuned.

The carbon that you use is also pulling stuff out of the water so that will effect how well your skimmer functions.

I also agree with feeding every other day. Been doing for nine yrs now. You might not have much to skim.

I only feed a little each time, but I'll try to cut back I was under the impression that smaller frequent feedings were better than bigger infrequent feedings...

I have about 8 kg of LR, a lot of it is in the sump.

Also, the Aqua C skimmer doesn't use a venturi, so there's nothing to adjust.

I`m not suggesting bigger infrequent suggestions as is none of the others. Just feed every other day regular feedings. You dont need to double the amount because it is every other day.

Feeding small amounts 2-3 times a day will yield the best results. That is closer to the way fish eat in nature, other than predators such as eels, etc. I've gotten much better coloration, growth, and activity out of my fish since switching from feeding every few days to twice a day. That is the way many hobbiest are doing it these days, due to better ways of managing waste/nutrient accumulation in tanks. Watch for algae out breaks. If you have a good skimmer, and do regualr PWC's feeding less, but more often will not be an issue. It will actaully benefit the tank. Just be sure not to over do it.
PS-No disrespect meant Melosu

None intended. It`s funny that I can say the same as your results but feeding every other day. I have fish in my tank that were with me at the begining nine yrs ago. I have not had ick or algea in the tank for 7 yrs now. Not bad for feeding every other day for nine + yrs.
