OK here's the deal. I just bought a 55 G tank which came with a filstar XP3 filter. This tank was previously used for salt water and had coral life. I want to use this tank for fresh water. The filter came with new foam pads for the bottom layer. Do I have to do anything to the filter or tank to convert the salt to fresh. I scrapped the tank of all the remaining coral stuck to it. Also when i was not looking my girlfriend wanted to help
so she tried cleaning the inside of the tank with windex.
Your help will be appreciated.
