| Media from shaved PCV pipe works but tents to become brittle and flow off in small piece to potentially clog your pipe. Some claimed that the chemicals on PCV retard initial bacteria growth until either wash off or biofilm establishment. So this media is not the very best, but why not using it while you have it?
Bacteria products are a complete waste of money. Mother nature give you good bacteria why pay? If you in a hurry, import some clean media from an established pond. stevec |
