so if you read my post a few weeks ago my TDS shot up from 2 to 40 in my 1000L tank.  I cleaned it and refilled it, which took 48 hours. 

So I have been working away fine all week, checking the TDS going in and even checked it yesteryear and it was 5 or so.

then we had the storm today and the tank is FULL to the top and the TDS is 35??

I threw some onto my windows and the spots where everywhere.  Well ped.

I tested the water going in and the tank so the meter is fine. 

What I assume is going on is that the green bacteria that normally grows on the top inside of the tank is killing the TDS.  since I dont normally fill up my tank to the TOP this is normally not a issue.

Anyway I have poured a whole bottle of bleach in and will let it soak overnight and clean it tomorrow and start again.

Am I the only one that has had this issue?

Soupy says that you might as well jack it in and get an office job.

Yep window cleaning ain't for you

Give it a good rinse out after 24 hours with bleach and you will be fine.

Is it sitting out in the sun? Or in a garage?

Its in the sun but its painted black.

If you've got the space, get one of those tin sheds. Great, cheap, last a life time and will keep your water pure for longer.

I'm lost here - how can a storm affect your tds? Are you collecting rainwater too?

[dazmond]

green algae in my old tank never affected my tds.it was always 000 so i dont think its that mate.bleach wont make a blind bit of difference IMO.

Have you tried putting your good water into a different container to see results the same?

I haven't the foggiest on how it got so high all of a sudden,  its painted black.

I have a few ideas how it got so high but not sure.  perhaps the flowers from the tree fell in there and contaminated it as I can see loads of small flowers half the size of your little finger nail.

Another theory is that I don't normally fill it up to the top but rather to about 900L and there was a lot of GREEN on the top 100L layer but the other night I let it fill to the top and it covered the green, this could have contaminated it.

I really don't know,  I just bleached it for the night and it was sparkling white.  Gave it a good rinse and started filling it up again.

An open top tank?
Stick a lid on it, your problems will be solved.
