138 ppm
S+ CRS Line

Switched to Rio Escuro from Amazonia and my CRS stopped crashing. TDS stabilized at 138 within a week. First berried female in month two.

Neocaridina Colony

The catappa leaves made a visible difference. My shrimplets started grazing biofilm within 48 hours. Lost zero from the last batch of 30.

Used the quiz, got the caridina kit. Parameters matched exactly what my Taiwan Bees needed. Molt rate is the best it's ever been at 5 dGH.
