Have just starting cleaning out my storage tanks in the garden (2 x 1000ltr IBCs) and two things.
1. I have had the same Hippo pump for 6 years, how reliable is that.
2. I have a layer of green gunge, obviously I need to provide a bit more shade!
I have scrubbed with my autobrush will now empty it but I cannot have got all the spores so it will come back unless I treat it I think.
Am I right in thinking some of you guys have used Milton tablets to clear this out?
