Slime in my R/O Water

[H20doctor]

I thought I would throw this one out there because I know it happens to those who make up RO water.
Question : I make up 30 gallons of RO water in a rubbermaid garbage can. Sometimes I leave it just fresh water, and other times I mix it up with salt. After about a week or two there is this slime that developes on the walls and the inside. Is this slime bad or good? Do I add this water to my reef or throw it out?

this is normal due to the plastic bin you r using .just make sure the temp and sality of the water is right before putting in the display tank

 

[tdksound2005]

it is safe

come on are you serious? isn't there some kinda nasty's in it?
The water is unheated and the can is a rubbermaid 30 gallon.

How long since you changed your RO filter cartridges? We were having that same problem, using filter cartridges that were around 15 months old. We got new cartridges and don't have algae in makeup water anymore. (The water takes quite a bit longer to filter now too). We have a couple brute garbage cans that have had water in them for several weeks now, still no signs of algae.

I have a 5 stage Ro unit, and the membranes are all good, I change them out once a year, I still think we should have a scientist look at this under a microscope. This really is not a big deal I just threw this up on the board to see what people thought of the slime in the RO water

Moved this thread to the chemistry forum, to see what our resident chemists think.

Do you have a pump in with the water to keep it circulating?

I don't think it is anything to worry about. When I have left water in my salt mix can (rubbermaid) I get a slight algea buildup on the walls too. I jut put it in my tank with no problems. Different algeas will grow in different conditions. Nearly any water exposed to air and time will grow algeas and plankton in it. The more nutrients the faster it will grow. Light conditions and other enviromental factors will contribute to the specific sort of algea that will grow. One that grows well in a trashcan with no light may not grow at all in one with a light cycle etc.

Just my opinion but backed by some experience...Sincerely...Collin
