Petco saltwater?

I am in need of some saltwater and the petco by me has big containers of saltwater for 89cents a gallon.
Is it okay?
I'm just not in the mood to be mixing water this weekend

 

im sure its fine. ive seen this off brand "petco" salt mix at my petco for like 30 bucks. i wouldnt trust it level wise in my reef tank and im sure thats what they use to make their saltwater

 

I would run some tests on it. Calcium, alk, mag, and salinity. If all checks out, I see no problem. I doubt cal/alk/mag will, though.

 

I wouldn't use it. They only use filtered tap water. It most likely will be full of nitrate and phosphate at whatever level your municipalities water comes out of the tap.

 

I would also check the SG as well.

 

There is no telling what contaminants are in that water. I would not trust they started with 0 TDS water before mixing in the salts.

I wouldn't use premixed SW from PetCo. Even if it were free and delivered.

 

I agree with above posts, unless you are talking about the containers that are prepackaged that are supposedly REAL Ocean Saltwater, like this:

PETCO Real Ocean Water at PETCO

I believe that this would be safe to use, because it is Natural Sea Water, though I would still be cautious with using it and test the params before just "adding it straight to the aquarium".


Still, the best advice I can give you is to use RODI water with 0 TDS and use your own salt mix, as this is the only way to have guaranteed safe results, especially with a reef aquarium. But in a pinch I believe that NSW is ok to use.

 

I used some of this and it test out well. salinty was only at 1.024 though everything else 0ppm no nitrate or phosphates
