Way more effort in your nano then mine that's for sure. Nice job!!

As for the probes, get them back into a SW mix ASAP, once you have filled the tank do the calibration, if they calibrate ok your all good.


Now GET SOME DAMN SW IN IT!!

Agreed although fresh water works fine as well. It's just the pH and Redox that you have to worry about, temp will be fine.

I thought those probes came with a mild SW mix in them? I could be wrong cause I never really tested it :biggrin:

I don't know what fluid it is but can you not use the probes for freshwater setups as well?

Not sure either but it's a good point!

the probes have what looks like a tube inside of them, with a few small air bubbles, so im assuming there is something liquid inside of them. They also have tags on them, the guy i bought the apex off of had them calibrated last month, they are also still currently in my plumbing with no water, but im going to charge that line with saltwater right now

You will still need to recalibrate once you get the system up & running just to make sure everything is correct.

Do i need the calibration fluid for that? cus i dont have any haha also i just looked, and i dont have any salt!! haha i sold the last of it with my old tank

do you think there would be any problem using table salt to mix up about 50ml of water to keep them wet, or is there any point is getting them wet again cus ill have to recalibrate them now anyways

Just throw some FW in the line for now & you could get calibration fluid from concepts when your ready. I just check a brand new ph probe I have & it's not SW in the cap.

pH probes are generally shipped with a neutral cal solution
Not sure about the redox ones

Nice work on the sump ... just one question
What are your plans for circulating the fuge water ? I only see a dam wall ...
Are you planning on a small pump to feed it ?
