Sump sitting static

[Marcom12]

So, due to my lack of planning, my sump return pump failed and while I await a new pump the water in the sump has sat stagnant. My question is : can I install new pump and just recirculate the existing water? It’s been sitting since Friday so as of this post it’s sitting at 3 days and pump is due tomorrow and I’ll not get to it until after work. So will be a total of 4 days.

I have my water movers going full blast in display to keep the biological filter working. so just wondering about the stagnant sump water.

I personally would drain and refill. I can't imagine that the water would not affect the tank. By the way, how's the tank doing? Are you checking nitrates? Good surface agitation?

Yes tank is doing fine. All numbers are doing well. Haven’t tested sump water.

I would let the water circulate for a few hours. Then get it connected back to the display. After a few hours of running that do a water change.

Do you have a nicely populated fuge? I am guessing no, as you would not want that to sit stagnant.

Nope just a basic sump with some cheato at this point

I wouldn't sweat it too much. Just let it circulate and get to a similar temp as the DT before connecting the two.

Wouldn't it be far easier and better to just drain and refill the sump with fresh salt water? I've taken a sump offline for maintenance and just changed the water entirely then fired it all back up.

Either way is fine. Use a pump and pump out the sump water or just let it circulate and do a WC when you get around to it. It's not like he dumped a strange fluid into in the sump it's just been sitting.

As always, the final choice is up to OP

I feel like that’s what I should do.... and was just wondering if people would think I don’t need to. It would be far easier not to. But I’m due a water change anyway, so I guess maybe I’ll just take the opportunity to pull sump out and clean it and refill with fresh. Almost feels if I don’t, I’m just being lazy lol.

If my sump were full of gunk -- or if I had any reason to believe any animals were dying down there -- I'd take the opportunity to vacuum it out and pour fresh water in.

If I felt like it was pretty clean and stuff was not dying, I might do an ammonia check first, then circulate with heat and restart once it was up to temp.

Now, go buy a backup pump. Used is fine as long as it runs.

Lol yes back up pump is on it’s way with new pump

I don’t think anything is dying ... it’s a pretty clean sump. 2 snails ...cheato ....tiny bit of live rock rubble .....

but ... feels like I’d be taking a risk... just a feeling even if unfounded.
