corky Posted February 19, 2017 Report Share Posted February 19, 2017 If it's sold specifically for pool filters it should be good, you could add vinegar or anything acidic to test it , if it fizzes its not good Quote Link to comment Share on other sites More sharing options...
HDBENSON Posted February 19, 2017 Report Share Posted February 19, 2017 Do you have any way to test pH? Add some sand to a jar with whatever water source you will be using for the plants. Test the water first. Then test the water again 24hrs after the sand has been added. Corky has a good suggestion, but I believe white vinegar is too weak of an acid to judge the potential pH of sand.

Rory Posted February 19, 2017 Report Share Posted February 19, 2017 Tried this and aquarium sand for my pygmy drosera, and the plants in the pool filter sand are doing great so far, I've also planted some sarracenia in this sand to see how they do this summer. Â Might be difficult to see, but the pot on the right has the pool filter sand. In that pot the plants are way healthier, lots of new growth etc. and in the other pot (with gemmae that were planted 3 weeks earlier) the plants haven't even made a carnivorous leaf yet. The pot on the right also has less algae. (Sorry for the bad picture, quickly took it with my phone) I never tested the sand (simply forgot) and so far it seems to be fine.

corky Posted February 19, 2017 Report Share Posted February 19, 2017 When using something new I always test it out on a sacrificial sundew just to make sure , but then I always have loads of spares normally where they shouldn't be growing Quote Link to comment Share on other sites More sharing options...
