StonedCold, If you feel we are hijacking your thread, please just tell us to stop.
Sticky_Budz, I just looked up that PH Down product and even the Technical Reference Sheet from the company does not list the ingredients. It just says it "lowers pH by neutralizing carbonate hardness in the water" and "contains no phosphates and may be used with live plants." I'm sure they mean aquarium plants.
The Pond Care, "EcoFix contains five strains of live bacteria that digest sludge and reduce dissolved organics, making pond water clean and clear."
Well, if anyone else out there has tried these, feel free to let us know.
If no one else has tried it, I might try the PH Down for fish tanks on one of my plants in the future just to see if it works. That wont be for a few months, however.
