Sorry to hear about your losses. That sucks.
I set up the NitraGuard experiment on January 19. Phosphate was 63 ppb Nitrate was 20 ppm. Tonight's test (one week later): Phosphate: 63 ppb Nitrate: 0 I'm not quite sure why it hasn't reduced phosphates (perhaps my rocks are leaching). Anyone know where I can get Foz Down in Vancouver? |
