Thanks guys. 🙈 🙉 🙊 looks like I am a monkey, gave this job a go today, customer was happy but I wasn't, I use it as a little learning curve. I need to get some proper chemical.
You can see where I poured the crap I used, I should of just put it in a bucket to mix, never mind. I will go over it again next week, there is a place in Runcorn the sells hypo so that's were I will be on Monday.
