What is the effect/impact of CO2 being off for 1 day?

[Bradders]

It will soon be time for some new fish. The Scapreline 100 high-tech aquarium is nearly seven months old, so it is time for new additions.

The awkward thing is that shop opening times and my CO2 schedule don't match. So my question is, if I leave CO2 off for one day to make sure the new additions settle in, is that going to cause any impact?

No

My instant reaction is that most fish sold and used within our hobby are fairly robust and would be fine. If you have any more sensitive fish I would use drip acclimation. So it depends on how 'sensitive' the fish are to fluctuations in water PhH.

There are, however, far more experienced people on this forum...

Dont turn off for the entire day. Turn off an hour before going to the shop, bring fish, let them swim for 30-40 mins and enable again. That what i do usually

If you leave the CO2 off there will be no impact.

The acclimatisation of fish is a controversial subject. I would just adjust the temperature and then plop and drop the fish directly into the tank. In my opinion, all other types of acclimatisation cause more stress than they are of any use.

It certainly is! To be honest, I also prefer the 'get home and get them in quick' approach rather than 30-40 minutes of acclimatation. Has seemed to be fine, but I dont usually tip in the shop water - just the fish.

That's a good compromise suggestion. I might actually run the photoperiod A LOT later for one day (from 13:00 to 21:00 to 15:00 to 23:00), which means I can get the fish in before noon before the CO2 starts.

This is the plop part. The fish in the net and the water from the bag into the drain. Just don't get it mixed up.😉

That is the method I use as well <"The Living Aquarium"> and for the same reasons.

I acclimatise for temperature and sometimes use drip acclimation (always with shrimp) but never introduce water from my LFS into my tanks. Is this problematic?

I can only see a problem arising with plop and drop (after temperature acclimation) is if the water parameters are vastly different i.e. from hard water to soft. I usually have a quarantine tank at the ready so the water can be altered over the quarantine period of four weeks or so.

I read the OP's question as impact of a one day CO2 break on the tank. The answer on that is generally no, don't worry even if it were a few days.

Acclimatising fish to a CO2 injected tank is generally seen as a potential risk, depending on fish/shrimp species and CO2 ppm.

Not only does CO2 create a pH difference, but also we could imagine CO2 osmosis into the fish body and potential harmful effects when the tank is injected at high CO2 ppm. Probably better to be cautious, as we have a couple of unknowns.

That is the method I use as well <"The Living Aquarium"> and for the same reasons.

But you're not injecting CO2?

Hi all,

..... But you're not injecting CO2?

No, it was just in terms of adding new fish to the tank.

I pour 3/4 of the water from the bag away through a net, because accidents can happen, and then place the bag in the tank and let the tank water flow in until the fish can swim out under their own steam. If they haven't left the bag after ten minutes, I gently tip them out.
