    Default Slime in cistern

    Hi,

    My toilet is plumbed to the rain water tank.

    Ever since the tank ran dry over summer I've noticed that there is a white slime coating the walls and floating on top of the cistern.

    I will post a photo tonight, but it looks like when you leave dirty dishes in a sink filled with water for a month and white sticky stuff forms.

    I've tried wiped it clean inside but can't clean it 100%. It looks OK for a week or so, but it returns.

    The 3 caroma toilets are all affected, toilets and tank are about 1 year old.

    I was thinking of bleaching it but worried it would damage the internal of the cistern.

    Any suggestions?

    Good Morning JB

    We had a green slime in a Fowler porcelain cistern - plastic innards are Caroma, I think - when it was unused for six months while full of tap water. An egg cup full of swimming pool chlorine worked well. Just held the ball float down a little so that the cistern filled well above the slime line, then added the chlorine. Next morning flushed the problem away.

    Thanks Guys,

    Bunnings stock pool chlorine?

    I thought the main ingredient of pool chlorine (and chlorine in general) is bleach???

    Can I just use bleach?

    Next time, I'm not going to plumb the tank to the toilet.

    I'll never recoup of the cost of the pump, plus the ongoing cost of electricity. Now this issue

    The other way around - chlorine is the actual chemical, and one of its' uses is as bleach.

    I use Domestos Thick. Just give a good squirt inside the cistern including the water reservoir. Leave for half hour and then flush. All clean and smells OK.

    I think using a cleaner would be ok when the rubber seals are new but if a few years old you going to speed up
    the deterioration of the rubber as I found out by doing similar with bleach , lasted a week before had to replace
    the blunger seal.

    That's what I'm worried about (bleach damaging the seals).

    I think I will scrub as best as I can, bleach it for say 30mins and then flush...

    Caroma washers are all of about $5 retail for the full set.

    Zero effect on my seals, etc. Just got rid of the slime and grot in the cistern.

    Swimming pools have lots of plumbing, pumps, heaters, etc, and they all seem to survive the chlorine.

    But would be a pain in the ass to replace in a wall facing toilet.

    Not easy go replace all the washers as you can't get access to the bottom of the cistern without removing the pan
