Aquavitro Shrimp pHa™ — Acid pH Stabilizer (150 mL)

$19.62

Aquavitro shrimp pHa™ is a pH-lowering buffer that replicates the acidic, ultra-soft blackwater chemistry of Caridina shrimp native habitats — primarily the highland peat streams of Borneo where Caridina cantonensis variants (Crystal Bee, Taiwan Bee, Pinto) originate. Its sodium-free buffer chemistry stabilizes pH in the acidic range without introducing sodium ions that disrupt the delicate osmotic balance of sensitive dwarf shrimp.

Shrimp Species Parameter Chart

Reference this when setting up parameters for each shrimp group. pHa is most critical for Caridina species requiring active soil substrates and acidic water to thrive and breed. Always use RO or distilled water remineralized to target TDS — tap water KH will continuously fight any acid buffer.

Species Group	pH	GH	KH	TDS (µS/cm)	Temp (°F)
Crystal / Taiwan Bee (CRS, CBS, BKK, King Kong, Pinto, Mischling)	5.8–6.8	4–6 dGH	0–2 dKH	100–150	68–74
Tiger Shrimp (OE Tiger, Tangerine Tiger)	6.5–7.5	4–8 dGH	1–4 dKH	100–200	68–77
Neocaridina (Cherry, Bloody Mary, Blue Velvet, Blue Dream, Red Rili)	6.5–7.5	6–8 dGH	2–6 dKH	150–250	65–77
Sulawesi Shrimp (Cardinal, White Orchid, Orange Eye)	7.5–8.5	5–8 dGH	4–8 dKH	150–350	79–86

Key Features

Lowers and stabilizes pH in the acidic range (5.8–6.8) for Caridina species
Sodium-free buffer system — won't disrupt osmotic balance
Also supports plant growth in shrimp aquariums
Use alone or as part of the two-part pHa + pHb system (pHa for Caridina, pHb for Neocaridina/Sulawesi)

Dosing

2.5 mL (½ tsp) per 20 L (5 gal) every 12 hours until target pH is reached
Dose can safely be doubled if needed
Always use RO or distilled water — tap water KH will continuously fight the buffer
