Aqua-Pics pH Up 2.5kg — The largest Aqua-Pics pH increaser, for shops and large fish rooms
A shop holding system or a large fish room can run through a 500 g or 1 kg pack of pH increaser within a season, and ordering the smallest size repeatedly is rarely the efficient option. Aqua-Pics pH Up 2.5kg (SKU: 724798) is the largest pack in the Aqua-Pics phosphate-free pH increaser range, raising pH by counteracting acid compounds across many tanks drawing from the same soft or acidic supply. The 2.5 kg size is working stock for a business or a serious multi-tank hobbyist rather than a single-dose product.
The dosing principle is the same regardless of pack size: Aqua-Pics specifies no fixed gram-per-litre rate, directs small amounts added as required, and warns against overdosing, since a rapid pH rise is harder on fish than a stable low reading. Once a tank reaches its target pH, Aqua-Pics recommends its KH Buffer to hold the level there, because the increaser on its own does not leave lasting buffering capacity behind. At 2.5 kg, the pack is kept sealed and measured out tank by tank for livebearers, African cichlids, goldfish and other hard-water species across a holding system, display range or breeding room. Pairing the increaser with Aqua-Pics’ GH Salt range addresses hardness at the same time, since soft water and low pH typically occur together across a shared supply, and retesting each tank individually before redosing avoids overshooting once several aquariums are on a shared schedule.
Usage & Application
When to Use
- Shop and wholesale holding systems: Many tanks needing the same correction.
- Large fish rooms: Several displays on soft or acidic water.
- High product turnover: Facilities that would otherwise reorder small packs often.
- Hard-water collections at scale: Livebearers, African cichlids and goldfish kept across many tanks.
Dosing & Administration Guide
- Measure per tank: Dose from the bulk pack into one aquarium at a time.
- Small, repeated additions: Never treat the full 2.5 kg as a single dose.
- Retest before redosing: Confirm pH has settled before adding more.
- Follow with KH Buffer: Apply once each tank is at target.
