To skim or not to skim

I'm getting back into things with a nano system... 7 gal tank and 5 gal sump. Are there any in sump skimmers worth a darn for such a small system? Is skimmerless the way to go?
 
No skim

No skim

Hi, I would say just do a 90% water change every two weeks and every week if things look like they are needed! In such a small system feeding can go negative quick but with a 90% water change you can insure that your water quality stays in tact :) Dont worry about pulling out your beneficial bacteria as it is in the sand and on the live rock! Just my 2 cents and good luck! Oh and welcome back to the hobby :)
 
Skip the skimmer

Skip the skimmer

We've been running an 8 gallon Oceanic Biocube (no sump) for a couple of years now and water changes are just fine for us. Your mileage may vary, but I think if you don't over load the system, you should be fine.
 
maybe an airstone driven unit ,if your going to bother with a sump. more for o2 than skimmate. i got one with my AIO ,it's not bad if u replace the airstone monthly.
 
What's your bioload going to be like? Light bioload and you're probably fine with water changes. Higher bioload might cause some problems.

I've run a handful of systems without skimming and had great luck. I had exceptionally low bioloads though.
 
The skimmer removes some organics and provides aeration. Granulated activated carbon removes organics more effectively. Regular small water changes help; very large ones can be harmful . Some corals do fine in water with higher organics. Some don't.
 
Appreciate the responses, but I guess I shoulda asked a more on point question:

Is there any skimmer that performs well in such a small system?

I was under the impression oversized skimmers won't be effective with less organics to remove, but most skimmers marketted as 'nano' are not quality skimmers.
 
Jay, I've got a 10 gallon nano with a 5 gallon bucket for a sump at the moment until I can get something that fits in my stand.....I have a HOB cpr skimmer on it, no other filtration. I just did a water change today, and it's been a month, and everything was still looking great. Skimmers that are marketed for nano tanks, IMO, are not worth it. If you're going to do a skimmer, I'd recommend getting one that's overkill for the tank. If nothing else, it'll definitely help keep your water cleaner and your critters happier. My tank did no where near as well when I just had a filter with carbon on it and no skimmer.
 
I am running a 2.5g nano with one green clown gobie and around 8 snails and 6-8 different corals, I top off with fresh rodi daily to replace evaporation and do like 30-40% water changes every 10 days or so, I have a small hob filter that I run with small rubble and a ball of chaeto instead of the typical carbon filled floss cartridge. The tank does get over fed a bit and I have some very very minor cyanobacteria patches that come and go but all in all it seems to be doing very well. The tank has been going for maybe 60 days and the fish has been in there for close to 30 of them. Most of the members here on URS directed me away from a skimmer and based on my experience with this small tank I have no problem doing the same for you, so my vote is no skimmer and use natural methods of nutrient export, and water changes.
 
He's alive! What's up Jason! Nice to see you playing with a system again. A skimmer that I would recommend would be the Tunze 9002 but that can get up to I think 50 gallons? It's up to you, I don't think a skimmer would hurt knowing that at times you get called out of state for days. Without a skimmer I would go for a small water changes pretty religiously.
 
Im setting up a nanocube i got that came with tunze 9002. Thinking about setting it up for seahorses/pipefish.debating selling skimmer if you are interested.
