So here's the dilemma. My nitrates are 35/40ppm and phosphate is 0.25. The system is 525L so large water changes take a while. The dinos go away, but then as soon as I carbon dose to bring down the nutrients, they start to creep back on the sand, a slight dusting. Forcing me to turn my UV back on and bubble scrub/ stir the sand.

Avoiding bio pellets and any carbon dosing is a given now, but how else can I strive my nutrients down and avoid dinos coming back?

Funnily enough, on the 26th December I sugar dosed, few days later light dusting... Started up bio pellets Saturday and today... Light dusting on the sand. Whipped the biopellets out and back to uv and bubble scrub.
