Thanks for clarifying I will carry on using the surfactant. Not fairy
Wise choice 😂😂 on a serous note you only need 300 ml of surfactant per 20 ltr neat drum of hypo so at between £20-45 per 5 ltr of surfactant ( depending what you use ) it’s cheap as chips anyway .
How does that work when adding water though? Let’s say you’ve got a 100 litre barrel and have 20-30l of hypo and the test water, surely you’d need way more surfactant than 4-500ml...
As you know I’ve always Used fairy, and only need a small amount in my barrel to make it ‘stick’
