I want to start mixing my own soil, now that I have over 10 carnivores plants it seems a little ridiculous to buy the premixed stuff, although it was convenient when I only had three. I’m curious if any of you have ever used the HTH pool care filter stand sold at Ace Hardware? I believe it is 16 mesh, although I am having trouble telling online. If not, what brand of sand do you use now?
I will be mixing it with coarse Perlite and Premier Spag Peat Moss.
I haven't tried that brand, but pouring some vinegar over a bit of it will test for alkalinity. If it bubbles when you pour an acidic liquid over it then it is alkaline and no good for growing carnivores.
A second test is to mix some water with it, drain the water , then test the water with a TDS meter(Available for $10 - $20 at AMZN). If the reading is below 50ppm, then you're good. Otherwise you'll have to flush and drain it until impurities are washed out.
But so far, all pool filter sand I've checked has been OK.
