Spar said:you sure spaghnum moss lowers pH?
at least the spaghnum I have doesn't appear to have any tanics at all in it. are you sure you aren't getting it confused with Peat Moss?
Spar said:you are actually right. went and checked my bag of Peat Moss. It is labeled as "Spaghnum Peat Moss".
I also use straight Spaghnum Moss for my frog tanks, which is much thicker and stringy, without all the tanic acids in it. I think it is labeled as "orchid spaghnum moss".
i know a guy that has lots of shrimp tanks. I will send him an email to see his experience with it.
