Can I use phDown by Wardley to provide phosphate to my planted tank?
Everyone says this stuff contains phosphate so I thought I'd try it.
Thx

Often if it's a pH down product and has PO4, it's 30% H3PO4,
phosphoric acid.
Roughly one drop per 20 gallons every 3 days or so will give enough
PO4 for the plants.
This small amount has no impact on pH though.
