been reading online about using play sand for plants and like always gettin mixed results. i was wondering if anybody have used play sand as a substrate for plants. i just like that grey color

I have used Play sand before from Lowes and Home depot, with sand from Lowes I had better results. Sand need to be washed and boiled. HD sand have too much crap in it, so do't use it you will have algae outbreak.
With any sand substrate you need to have Malaysian trumpet snails.
They never eat any plants, unless plants are already dead. I don't see them most of the day, as they root through the substrate for missed food or rotting vegetation. They are GREAT for planted tanks, keeping the roots of the plants healthy by moving the substrate around and keeping things from getting stagnant. A great addition for any planted tank!
The sand by it's self dose not have any nutrients for the plants but after about six month fish, left over food, dead plants and all that good stuff will get nutrients for the plants.
Good luck.

thanks for the info. were you using quikrete?

Agree ^^^ Definitely use the silica sand. You will have to add nutrients for the plants but You just have to rinse it off really quick (we used a large rubbermaid) and dump it right on in!

i have play sand in my 55 gallon. i just rinsed it a bit in a bucket then poured it in, works great and is really clean

play sand in my 20gal and half play sand/half argonite crushed coral in my 55gal and 50/50 playsand/tank sand in the 80gal works great, enjoy the natural look even though ive only got 1 real plant
