I'm going to look into overnighting it today.
And i could do the water change with store water but i think on a 180 gallon tank that has god knows what leeching into it that it will take way to much bottled water.
I just thought if a store has one there then it would be easier for me to drive up this afternoon and just grab one from there.
I don\t know why the membrane is shot anyways although the water where i am is brutal so that really explains it...
