Playsand is indeed safe to use and doesnt affect your water parametres. I use it in all my tanks.Hey guys, had a question, is play-sand as a substrate safe for fish? And will it affect water parameters as far it goes?
All right then, appreciate all of your inputs and answersHello again. I think you could use sand. It's not wrong to use it. But, pebbles are easily vacuumed if any fish or plant material falls into it. The pebbles allow water to flow through the spaces easily, no water aeration issues. Sand on the other hand, is easily disturbed and debris could float around the tank for a short time. Try the sand if you like. I think you'll find the pebbles easier.
Everybody's different. Thank God for diversity!

I realized we never answered your question directly. If it's playsand, then it should be as safe as any substrate. Sand will vary depending on where it comes from, but it's generally very similar in composition.
After that, you have us with our preferences, and you deciding how it would work with the fish you have or want.
I use, SAKRETE PLAY SAND, is that fine?Some brands say that they aren't aquarium safe. If you're in the US, you want to use Quikrete. In the UK, you want Argos.
Otherwise, play sand is pretty ideal. It's soft so it's good for bottom dwellers like corys or fish that like to dig like cichlids. It looks natural. Add some root tabs and plants grow in it. Andit's very affordable.
In my experience, MTS only burrow through about the top 1/4 inch of sand, so I'm not convinced of their value. However, plant roots will keep sand aerated.* So either keep the sand fairly shallow, or have it deep with lots of plant roots (crypts and swords are especially valuable). No burrowing critters necessary.About the sand compacting-if you have something like Malaysian Trumpet Snails or Rabbit Snails they disturb the sand themselves.
However Malaysian Trumpet Snails multiply fast, and some big Rabbit Snails can accidentally uproot plants and I am assuming decor.
