So, UPS has lost a package that contains my new return pump. I had to order a new one because the old one doesn’t fit in the pump section of my sump. Since I don’t have it, I’m running my old pump and have it in the skimmer section of the sump. That means no skimmer. UPS is trying to find the package but in the meantime, how long can I go without a skimmer? I’m worried about gas exchange/aeration more than protein export.
 
The short answer...forever. Skimmers are not essential but are useful. If you are concerned about gas exchange point a power head at the surface. My returns empty just be low the water line as a safety factor for power failures and I don't really need my skimmer for aeration.
 
Which size tank are you referring too? I see you have a few in your signature. Also is the tank heavily stocked with fish? Most tanks can survive no problem for extended periods of time without a skimmer, or without one at all. Maybe just direct flow upwards with pumps to break the surface for better aeration.
 
you should be fine. I wouldn't worry about it.

You have an overflow, which the water then goes down and gets oxygenated when it enters the sump and causes turbulence. If you're really concerned about it, add a spare powerhead to the display and aim it at the water surface.

I would only be concerned if you're running biopellets or something similar that will cause a bacterial bloom with no skimmer.

I just set up a new 90 gallon and combined those tanks into it. I guess I need to update my signature! The dimensions are 36x24x24, a 90 tall I guess. I have an MP40, MP10, Tunze Stream, and 1k gyre. There’s plenty of water movement at the top of the water. One problem I’ve always had is pH. I run a CO2 scrubber on my skimmer to help maintain pH. I also had a refugium (of sorts) on the 60 that I don’t have now. My house is new and tight as a tick. pH drops every night to 7.8 or lower (last night it was 7.7). So, my skimmer helps. I also have to keep my dkh a wee bit elevated to maintain pH. Lack of skimmer for a long time scares me a little. I’ll try to not fret over it. Thanks guys!

Nothing like that but I’m glad you mentioned it!

Not sure if temp is an issue but you could always open some windows/doors for extra oxygen in the room. This will help with PH. May not be as good as a skimmer with a scrubber but couldn't hurt to try.

You might test your CO2 level in your house. And a simple experiment to try on your system would be to get a cheap air pump, set it in a protected area outside or in an open window, run an airline to your tank and let it bubble in the sump. If you see a big increase in pH you may want to think about running the air supply for your skimmer outside or keep an airpump outside feeding yuor tank.

Do you have power heads in the tank agitating the water surface? Because that will help oxygenate the tank.

Wish I could. In order to do that I’d have to drill a hole through my roof. If we live in Arizona I might try it but we get so much rain... besides, hubby would never go for it.
 
It seems like your problem is solved but just for example, I just went 2 weeks without my skimmer. There's a few reasons why I tried it, but that's irrelevant. I do have an overflow and the returns pointed to the water surface so I wasn't worried about aeration. Mostly everything is doing just fine, but I did a water change and turned the skimmer back on last night.
 
My skimmer just stopped working randomly, it gets so much fish poop and funk out of my tank it’s hard to imagine my tank being ok for an extended period of time. I don’t have a ton of rock in my tank so the fish have more swim space but that also means less bacteria from my understanding. Anyway I threw extra bacteria in my tank today and I’m thinking of doing small more water changes once a week to help.
 
I run my 40 breeder without a skimmer. I use biweekly waterchanges and a reefugium. Other than some hairalgae everything is growing well. Softies are happy as well and lps. I have put in a few sps several weeks ago and they are beginning to encrust (except an anacropora). The hair algae occured several months ago when I upped my feeding regimen to increase growth on my lps. The algae was bad for a while but Im starting to slowly get it under control. From my experience keeping everything skimmerless can be done but you have to be careful with your nutrient input (which I wasn't) or you will get algae. Im happy with my tank and the growth I've gotten from it but I am considering getting a skimmer so that I can feed my corals even more without feeding the algae.

Just an FYI but if you're keeping any corals fish poop is thier preferred source of nitrogen and phosphate and fish poop is also an important component of the carbonate cycle on reefs. Here's links if you want to read more:

"Forget what you know about phosphate and nitrate"

COntext dependant effects of nutrient loading on the Coral-Algae mutualisim"
(Nitrate dosing can shift coral-algae mutualism to a parasitic relationship in favor of the algae.)

"Fish as major carbonate mud producers and missing components of the tropical carbonate factory."

Here's the oldest system I've maintained without a skimmer:

That’s awesome!!! Thank you for that info. I don’t have that many corals in my tank but I see what you’re saying.

That blue hippo looks weird. Do they all look like that when they get big?
