Just a gentle reminder..... Always check your water

Received this high quality 1.030 water from my local fish store. Luckily my water making station goes up this week.


Always check your water before a water change. Always. It's your thousands of dollars tank at risk.

How have you calibrated that? If you’ve used DI, the water may be good, you’re tank may be low.

Not great but if you're relying on LFS water, there's going to be variation. A 20% water change at 1.03 would raise your SG to 1.0268, assuming you started at 1.026. That's not going to harm anything.

It's calibrated. This was the first and last time I went to this store.

I was doing a much larger change due to recently dosing fluconazole for bryopsis. This would have done some damage in my small 13.5 gallon.

Very odd for an LFS to be giving salt away, but hey, free salt, lol

On a side note @Garf what calibration fluid do you use? I'm going to order some new stuff and I figured I'd branch out.

Just curious on your refratometer.
What I outlined saying 20 °c ?
Does this mean test needs to be done at 20 °c temperature and its not an "atc" refractometer?
Just curious is all and just wondering if you need to test at 20°c and you tested at 25°c-26°c could it give you a higher reading.

Mine is an atc and doesnt have no temp mark where yours does so just curious is all ^_^

You should let them know. Whatever they are using to check their salinity might not be right. I'd give them another chance if they apologize.

I measured it at room temp. So it was probably about 20-21c. This wasn't heated water.

That's an interesting question though and not something I realized was on there.

I let them know. This was my first time buying water there and the last. They have a good coral selection. I'm finishing up my water station so luckily I'll be self reliant.
