Silly Question

[gulf coast reefer]

Hey all. I have a “dumb question” lol

had a friend do a water change while I was out of town. I think he removed more water than he added back. I have a Red Sea 170 and have adjusted the flow perfectly before so there’s no gurgle and right amount of water in sump. When I got home the sump level was low and return pump was pushing air. Figured the flow valve was messed with but it wasn’t. So here’s the dumb question…..I don’t want to mess up my specific gravity. Can I add my pre mixed saltwater I have to raise the water level or should I add RODI. I would like to take care of this ASAP. Any help would be greatly appreciated. Thanks…hope everyone is doing well!!!

If it has the right sg still, put in saltwater.

test for salinity. then plan accordingly. is salinity low? add saltwater. is salinity high? add RODI/FW.

I actually just double checked SG and it raised to 1.029. Oh boy…. When I left it was 1.025

Sounds good. Just double checked salinity and it raised to 1.029 so I’ll definitely add RODI

Take some out and add top off.

Maybe I have a slight issue with my ATO as well. Tank only 6 months old haven’t had issues yet. Remove salt and add fresh

Yes remove the sw from the tank and add fresh to either the top off or the actual tank. Re test and do until 1.025-1.026

Calibrate refractometer with calibration seawater solution as well.

Tried adding a photo it didn’t attach. Got it down to 1.025. Thanks!!

If your mix is the same as the tanks current SG then it will stay the same. If it's from evaporation your SG should be higher and use RODI water to bring it back down.

Depends on if loss is from evaporation or just not filled/topped off correctly.

A lesson I just learned to keep an eye on
