I guess in the grand scheme of things it's $15 per litre of rocks so it's not like it's a huge expense but still it just feels odd to me to throw them out. There's only so many times you can toss this stuff under your deck or in your garden..

What about Carbon, Filter Media, excess tubing and even the Bananna peel you threw out this morning? Tony stop being a pack rat you can't use everything you throw in the garbage, I guess thats why they call it a garbage right? Still I do understand where your coming from, to have so much stuff produced only to be used and thrown out? An interesting topic to discuss would be does anyone think that the only reason we havn't produced something like a media which never has to be changed (or in a larger case a "never ending fuel supply") is because the people who develope these make money off having to buy a new one everytime? On topic though if the rocks are being used as a media to remove Phosphates/ Nitrates then over time they do loose that ability (Think of it as a Movie theater if you have 300 seats and 300 people (Or impurities in real life) theres no more room for those people to sit, there for the movie is full and so is your filter media)
