Pond Boss Forums Thread Like Summary - Large river stones for a low maintenance beach?

I’ve read the advice suggesting that a pea gravel beach would eventually turn slimy due to anerobic decomposition of organic material that works itself deep into the gravel layer with regular foot traffic. But what about large river stones? We have a local quarry that sells heavy baseball sized stones for landscaping. Our beach construction plan is to put down a 12x12 layer of geotextile, create a lip around it with cinder blocks, and cover it with a layer of these large river stones. I understand that this will be pretty uncomfortable underfoot, but our kids are used to walking on sharp rocks in the creek, and we’d rather have a rough beach than a mucky one. The stones are large enough that they won’t shift with foot traffic and the layer will be thin enough that there should be no tendency toward anaerobic slime. Does anyone think this strategy will avoid the issue of a mucky bottom? Or should we just use fine sand assuming it would be more impervious to organic material? Which do you think would require less maintenance? Fish habitat is of little significance to us since this is mainly a swimming pond. Thanks!

Sand beaches in fresh water ponds turn into a slimy mess if you don't keep up with the maintenance.

I put a gravel beach in my pond. The dog likes it, the RES like it, and it's good for putting the boat in.
It's also really good for growing FA (snot grass, pond scum, green slime). I rake it if the grandkids
want to get in and splash around. That's not a pleasant task for worn out old man.

Everyone here prefers to use the dock for getting in/out of the water when swimming.

That said, if I was really serious about having a swim beach I'd start by laying some sort of geotextile
fabric, then come with 3"-4" clean chat rock, top that with 3"-4" of man-sand, and stock up on
aquatic weed killer and algaecide.
