I have a beta and an African dwarf in a 20 g tank. Would this work for them?
Answer by ChewyAug 01, 2021
This substrate is suitable for freshwater aquariums and brackish aquariums with proper buffering.

will this gemstone gravel work for kuhil loaches
Answer by ChewyMay 09, 2022
Gemstone creek is safe and will not harm kuhli loaches. It may be better, if the loaches are a focus, to use a sand.

how large are the pebbles and rocks approximately?
Answer by ChewyMay 02, 2022
Each grain measures approximately 0.25–1.0 millimeters in size.

Can I use this in planted betta tank?

Much larger than advertised

The Chewy team posted that this gravel had an average particle size of 0.25-1mm and the CaribSea website says 1-2 mm. The gravel I received is actually much larger (I would say 5 mm average) and not suitable for my fish.

Wet dusty rocks

I have received these twice and both times they are wet and very dirty. Will not buy again.

Fine enough, but gritty

Fine enough, but there is a lot of small gritty pieces that need to be washed away

Beautiful substrate.

This is exactly what I wanted for my aquarium! The colour and the size of the pebbles are perfect. The description of the size is wrong though. In reality the pebbles are about 3mm in size with variations. Highly recommend!
