What do you plan to learn? That the in pond filter is too small and you need to upgrade? I'm already letting you know. I'm trying to save you some money and your fish some pain. If you want to learn "dynamics", get yourself an API water drop test kit. Learn about the cycle of a pond. Learn about ammonia, nitrite, nitrate, ph, kh etc.daboneman911 said:Nothing that I said indictated that i wasn't takin advice. And why can't I opt to just learn the dynamics anyways while they're small. They will get bigger, i know that. I will cross that bridge when it comes.
