The tank hoses have black gunk in them which keeps clogging strainer.
How can we get rid of this stuff and flush out the hosing.
I know we need to sanitise with mil tons but how do we get rid of the build up in the hoses

So I gather your fresh water hoses are clear plastic. The reeson for the "Black Gunk" is algal growth which only occurs with exposure to light. The way to stop it is to first get rid of it by adding a bottle or perhaps two of white king chlorine bleach to the water in your tank. Or liquid
pool chlorine will do the same job. Need a bit less though, probably only a cup full in your tank. Fill it with water and pump it through the lines then let it rest for an hour then pump it again and repeat until the tank's empty. Once you've done that and the pipes are pristine then you need to cover your clear plastic hose with that black plastic split tube they use for electrical wires.
Or you could just replace all the clear plastic pipes with
drinking water grade black poly pipe.

It goes without saying that you should flush your tanks and pipes very
well after the chlorine treatment.

About 40 years ago, I worked on a station that had a 30K gallon
water tank on a knob about 60-80 feet high, behind the buildings. As the tank didn't have a lid on it, the water often developed a fair bit of algae in it.
The previous manager advised me to use a quantity of Bluestone(copper sulphate) mixed with water, and scatter this over the water in the tank. Day or two later the algae had gone, along with that taste.
Can't remember the exact mix, probably 2-3 cupfulls in a bucket of water. Perhaps if you were to use a tablespoon of bluestone per tank, leave for day or two, then rinse thoroughly, your problem should be solved.

Thanks Bob and to everyone for their great advise. We took off the large hoses leading into tank and cleaned them out. Smaller hoses still hunky but better with the bleach and letting taps run thru.
Going to Bunnings tomorrow to get some piping to cover what we can for now.
It's amazing. Phoned some caravan repair
places for advise before getting onto
forum and they Were no help said they had never heard of it before.
