Description
Dainichi Ultima Krill 2.5kg Medium (5mm) Sinking Pellets — Bulk krill pellet for fish rooms and large adult cichlid collections
A fish room or club holding a wall of tanks full of large frontosa, peacocks and Central American cichlids goes through a 250 g pack within days, and reordering retail-size bags on that schedule is its own chore. Dainichi Ultima Krill 2.5kg Medium (5mm) Sinking Pellets (SKU: 101474) is the 2.5 kg bulk pack of Dainichi’s Ultima Krill formula in the 5 mm Medium sinking grade, the same shrimp-and-krill recipe sold in smaller retail packs but scaled for continual feeding of large, mature cichlids. Spirulina algae supplies the colour-enhancing effect and calcium montmorillonite clay supports digestion in a protein-dense formula.
The guaranteed analysis is unchanged at this size: crude protein minimum 43%, crude fat minimum 6%, crude fibre maximum 3%, moisture maximum 9% and ash maximum 9%. Wheat germ and wheat flour are the only starch sources, soybean meal and brewers yeast round out the amino acid profile, and milk powder, vitamin mix, mineral mix, garlic, beta glucan and protease complete the recipe. Dainichi’s feeding directions apply regardless of pack size: two to four times daily, only what is eaten within about a minute, and never pre-soaked. The 5 mm Medium grade is the largest in the range, and 2.5 kg is a bulk commitment suited to a fish room, club or several large-cichlid tanks rather than one lightly stocked display.
Usage & Application
When to Use
- Fish rooms and clubs: Bulk feeding across several tanks of large adult cichlids.
- Multiple mature display tanks: One bag feeding a collection of frontosa, peacocks or Central Americans.
- Proven formulas only: Buy this size once fish are confirmed to eat the Medium grade.
- Daily high-volume feeding: A high-turnover staple rather than an occasional supplement.
Feeding Guide
- Two to four feeds daily: Offer only what is eaten within about a minute.
- Portion by tank: Divide the bulk pack out per system rather than overfeeding one.
- Never pre-soak: Soaking is said to leach out colour enhancers and vitamins.
- Reseal between uses: Keep the bulk bag dry to protect the vitamin content over time.
