Is this gravel ok for my fish?
Shop QUIKRETE 50 Lb. All Purpose Gravel at

I believe that's what I got. Was gonna see if it worked and tested the PH in a bucket of water and stuff.

What do you guys think?

i've never used it....I've always used gravel sold at the LFS...

good idea to test the pH in a bucket tho

others will be along.....i can't say one way or another

Definitely check it to see if it buffers the ph. Use a few drops of your nitrite test solution on some pieces and see if it bubbles. I think it's the nitrite and not the nitrate solution. It's more acidic than vinegar to determine any reactions. I'll try to verify which one.

I can't find where I read that. I did just find that ph down is strong enough to test rocks to see if they fizzle. The post said there was a seminar where the guy said vinegar is not strong enough to test rocks but the ph down stuff is. If it fizzles it's not good to use.

I'm pretty sure the stuff will be fine since it's just rocks it's not like coral sand or anythinggg... for my nitrite test I think I have 2 different bottles... to drop in?

Wouldn't it be easier to just let it sit in water for a bit then test PH?

Ohhh, aquariums? sweet. I saw fish ponds on the thing so I assumed it was probably be ok. But good to know. I'll still wash it very good and test just in case.

One of the bottles for the nitrate test is a strong acid (HCl I believe) but as I recall you don't have a nitrate test kit. But if it says aquarium safe, I guess you're probably ok. I'd still monitor the pH, though.

Ok, thank you. :)

I was thinking of putting my angels in the new tank... Just taking the filter off the 44 gallon, putting it in the new tank, and then moving all the water. Bit worried the gravel will harm the angelfish... so I'll have to think about that. Don't want any harm to the water quality that will kill my angelfish. :( Hmmm, well I guess I'll figure it out.
