"pH errado matou meus peixes? Os 5 números que você precisa controlar"

Your fish died, and the water looked clean. Understand what happened — and how to prevent it from happening again. The biggest pitfall of small-scale fish farming is trusting what you see. The water may be clear, odorless, without any strange color — and be completely unsuitable for any fish. The compounds that kill fish are colorless, do not cloud the water, and leave no visible clues until it's too late. In this video, you will learn about the five parameters that separate water that breeds fish from water that kills fish: pH, ammonia, nitrite, dissolved oxygen, and temperature. Not abstract theory — these are numbers with names, with ideal ranges, with critical limits. And when you know these numbers by heart, you will see what the human eye cannot see. What you will learn: — Why clear water can be a silent graveyard — The ideal pH ranges for tilapia, tambaqui, pacu, pirarucu, and catfish — How pH fluctuates on its own throughout the day — and what to do to control it — The difference between ionized and non-ionized ammonia, and why this changes everything — How nitrite acts in fish blood and what the nitrogen cycle is — Why tanks die at dawn — and how to prevent it with aeration — How temperature amplifies the effect of all other parameters — How to monitor water quality without spending a lot: pH meter, colorimetric kits, reagent strips, and oximeter Equipment mentioned in the video: → Digital pH meter: R$40 to R$150 → API / Sera colorimetric kits: R$80 to R$150 → Multiparameter reagent strips: R$30 to R$50 → Portable oximeter: R$200 to R$500 With data, you stop putting out fires and start preventing them. 🐟 Subscribe to Peixe Pequeno and activate the bell so you don't miss any content about fish farming, tank management, and sustainable production. #fishfarming #waterquality #fishfarming #tilapia #tambaqui #peixepequeno #aquaculture #familyfarming #fishtank #ammonia #oxygen #pH
