Water Aeration

I downgraded from 125 to 40 gal. I had 125 mixed reef tank for last 10 years so maybe my question sounds stupid. I consider myself experienced reefer after all those years but I have one question. I always mixed water for 2 changes. I used 55 gal of water and use it for 2 water changes. After using half of the water remaining was left for 3 weeks with our aeration. Then before another change I plugged pump 24 hours before change. I never experienced any problems but I know some keep saying that we should aerate water all the time. Im asking because now if I mixed my water it will seat for a lot longer since it will be enough for 3,4 water changes instead of only two like before. Do you think that will be a problem? Thanks.Art.

 

Not a stupid question at all.

Assuming that you use RO/DI water and keep it sealed to prevent contamination, freshly-mixed seawater will last a long time without aeration.

Always a good idea to aerate for 24 hours before use to ensure your O2 level is good.

 

Yes. It is RODI water. I also have covers and try to make sure nothing gets there ( it is in laundry and my wife often hangs wet clothes around)… I have to keep an eye on her… Thanks.

 

Sorry to hear about the down grade but dido on the aeration before using
