What do you think? Trying to make it a little more interesting for Gilbert. Some people say it's a good substrate as they can pick through it.
Ditto!Most don't recommend sand as it can trap waste and debris and quickly become a problem. A better choice is a shallow layer of gravel.
Gravel would trap more debris than sand and much more quickly
I have a small beach area in my pond surrounded by gravel, only like 1’x1.5’ and less than an inch deep to prevent the trapped ammonia danger. The fish seem to enjoy it and it gives a little bit of visual interest to the pond. I did have to scoop up and rinse out the sand around the one year mark as it was looking a bit green/grey, but it cleaned up easily with just swishing it around in bucket with pond water and since it was such a small amount it wasn’t a big deal. I think having the whole bottom sand would be a problem to keep clean and safe unless you are keeping fish and invertebrates that specific like to burrow in sand and thus churn it regularly in which case know it’s not going to look pretty as the years go on. My understanding of the ammonia poisoning danger is that sand can become layered upon decomposing material and water doesn’t pass easily through sand. If you don’t have animals regularly digging and tunneling in the sand, the products of decomposition build up in place and then if the sand is later disturbed it can release a methane bubble that will kill any fish in the immediate area.What do you think?
