Technical notes on aquaculture water quality, leather process chemistry and fertiliser blending — what the numbers mean, and where a problem stops being fixable. One new article every fortnight.
Spring stocking is won or lost in the weeks before. Bottom first, then water chemistry, then minerals — and why the order matters.
Read article →A hide that is not fully rehydrated carries the fault into every stage after it. When a wetting agent is enough, and when a soak needs an enzyme.
Read article →Above about pH 7.5 an iron chelate lets go and the iron precipitates out of reach. Why EDDHA holds where EDTA and amino-acid iron do not.
Read article →A chelating carrier, an organic nitrogen source and a biostimulant claim in one line item — and what it removes from a blender’s raw-material list.
Read article →One dissolves into the water column in minutes, the other works at the pond bottom for a fortnight. When to reach for each, and how they fit across a cycle.
Read article →Two acids, both ammonia-free, both in our range — and they do different jobs. A plain comparison of sulphamic acid and formic acid 85% for tannery deliming, pickling and descaling.
Read article →Australian prawn and finfish farms live or die on a handful of water-quality readings. Here is what each one actually tells you — and the point in the cycle where it stops being fixable.
Read article →Most grain complaints are blamed on liming or finishing. Often they start in the chrome bath — in how fast the pH came up. Here is why gradual basification matters, and what NEOMAG-90 does differently.
Read article →Every product in our leather range holds ZDHC Level 3 — the highest conformance level of the Zero Discharge of Hazardous Chemicals programme. Here is what that means for your treatment plant and your paperwork.
Read article →Traditional deliming leans on ammonium salts that load your effluent with nitrogen. DELIME-A and sulphamic acid offer a gentler, ammonia-free route — here is how they work.
Read article →Send it through. If it is a question your peers are asking, it becomes next week’s article.
