Is this safe for beta fish?

Is this safe for guppies?
Answer by ChewyMar 10, 2022
This substrate is safe for guppies since they are tropical fish.

Is this sand soft ???
Answer by ChewyMay 16, 2022
This substrate is soft-belly safe and features smooth grains.

would this be a good substrate to grow aquarium plants in?
Answer by ChewyApr 15, 2022
This substrate would be fine for plants. It would provide a good substrate to root in. This does not provide any nutrients though. If you were to use it as a Planted substrate, you would have to add fertilizers for plant growth.

As advertised

Description is accurate regarding grain size of 0.25-1mm, and this sand is pretty uniform in grain size (very very little sand outside that size range). Rinsing 3 times was sufficient to remove any sand dust. Website still will not allow photo upload, despite being well under the limit of 5mb.

Glorified play sand

To no fault of Chewy. Great price, fast shipping. Caribsea showed it as coarse sand to micro pebbles. This is fine sand. I have very expensive filters. This would wreck impellers and motors. And nearly impossible to vac. Now I will have top notch horseshoe boxes this summer.

TOTALLY IMPRESSED!

Didn't think I'd like it, but it's the best I ever had! It's safe and will not harm fish, keeps water clean, and beautiful to look at. I'm totally impressed!

Great unfortunately one bag came with tear at side have to reorder a replacemet

Wonderful got two bags of this and two bags of another sand for contrast, unfortunately one bag was packaged for shipping and it clearly had a tear in side instead of replacement before shipping they shipped it and sand about 1/2 cup was in the box when delivered.

Pre-washed and Beautiful

This sand says it comes pre-washed and it really does. I added about 40lbs of sand and my water was barely even cloudy. That small cloudiness settled and cleared up within a few hours

The sand turned out to be really nice and beautiful I enjoy having it in my 3 gallon tank that I just set up

Better than I expected

Was afraid it wouldn't be white or the grains would be too big but it's perfect
