    Carbon question

    how long should i leave it in for? i just had a scallop die and im questioning possible pollutants, since my girlfriend painted the wall near my tank the night before it died. i found a small dot of paint splatter on the top of my tank support, so im assuming that a drop might have entered the aquarium. its not oil based paint. i just want to be safe. i was out of carbon so i ran out and picked up some crappy hagen aquaclear refill to place in my cannister filter. i just put it in and was gonna leave it in over night. is that long enough?

    well, its not really a great idea to paint with an established tank but that being said I wouldn't fret much about it and even a little drop of latex acrylic probaly wouldn't have killed your scallop over night. tell me it wasn't a flame scallop they don't do well at all in aquariums and need turbid water to survive. was it one of those rock scallops/mussels that sometimes come in imbedded in live rock? I find they don't always last as well.

    fisherman,
    over time carbon leaches pollutants and phosphates back into the aquarium. FYI.

    i just want to give the water a little polish for safety sake

    Indeed. and also, I was told that some carbon packages are only good for a couple of days, but I'm not too shure about that statement.

    You can test your carbon to see if it leaches phosphates buy using a phosphate test kit. Put freshwater in the test tube, add a few grains of carbon ( you have to make sure they sink) Add the chemicals as the kit calls for. If blue trails start coming off the carbon it releases phosphate.

    Here's a fairly informative link, kind of a "all you wanted to know about carbon, but was afraid to ask" sort of thing. Although I found his recommended amount of carbon at the bottom of the article on the large side.
