Is their a product I can put in a tank to clean it out, it's quite green and can't get in very well with a jet wash. 
Thanks

Any idea how much I'd need to put in a 650 tank?
Thanks

I put a 750 ml bottle of household  bleach into my water from time to time preferably over a weekend. Miltons is only a  Sodium hypochlorite pill as used in many swimming pools.The problem with these pills is that are stabilized with copper and will push you TDS up  and will damage your RO if it goes through one. It could stain glass over time. One can see it in your blond hair if you swim a lot on holiday.
If you use bleach stir it in over a weekend leave the tank uncapped so that the chlorine evaporate out of the water,and clean window with this water if its pure.

Maybe you should take up soft washing instead as not many soft washing bods need to clean there tanks out because of algae or wriggly things growing in them.

Fill it with say a 2% hypo mix and then go and earn some reall money render cleaning instead while at the same time it's cleaning yer tank as you work...Kills two birds with one stone and all that or anything else you like

Smurf : does the Soft wash damage your pump or not.

hypo will not do a shurflo pump much good but a flojet pump will be much beta 

[Smurf]

You can get Shurflo chemical pumps and other brands which are more suited than the standard  wfp pump.
Some use the standard shurflo pump for chems but even when flushing them through with water regularly I would have thought they would eventually pack in sooner rather than later.

Thanks Smerf.  I guess it`s the metal parts in the pump bellows that will erode. Most are rubber but have valves that might have metal pins. Thanks anyway Mate.

The pump we use should not be affected with hypo as they have no metal parts in contact with the water its self.
