Marine buffer gone bad?

[JingoFresh]

I had about 30 gallons of fresh RO/DI water made, which after a day of airing was ready, with the salinity exactly where I wanted it to be.

The PH was slightly low, so I added some Marine Buffer to get it higher before mixing with my main tank.

The marine buffer was older and exposed to the air through a crack I didn't see. Adding it to the water made it very cloudy, however the salinity or ph were basically unaffected.

I had to put this back into my tank for water quality reasons, but am concerned about the cloudiness and if I should be concerned for my fish.

As I type this, it is mainly clearing up though.

There was a strange slime in the bin I made the water in too. What was it?

Thats a standard precipitate reaction, for more info see here:

Do you maintain motion in your salt water? pH can become depressed simply by absorption of CO2 from the atmosphere - having surface agitation will drive the CO2 off. I would not add buffers to water change water unless you were making specific adjustments with your tank water in mind.

Stuff can grow in storage tanks, especially open ones. Its common enough IMO.

I had three powerheads going in the tank, and the slime didn't appear until a few hours after putting in the buffer. It didn't grow in only 2 or 3 hours, did it?
