Environmental problem?

I was cleaning my saltwater fish tank and doing a water change today and got to thinking. Are saltwater fishkeepers increasing the salinity of the world's oceans when we do water changes? After all the salt is synthetic, so it didn't come from the ocean, but that where it will end up. Any thoughts?Environmental problem?Very good question. If you dump it down the drain and you live in a city, it probably goes where the toilet trout go. Most cities have sludge/**** pens where all the waste is collected and dried and dumped somewhere else. If you live rurally you might have a septic tank and depending on how much salt water your pouring in it might effect it's natural abilities. Either way, I don't think your saltwater from your fish tank is going to make it to the ocean.

If you really want to know, do some research on your local septic system.Environmental problem?
I'm sure you have larger, more easily remedied negative effects on the environment.Environmental problem?You could put it in a tub or large drip pan out in the sun and let the water evaporate out, the crust left on the surface of the container would be salt. I'm not suggesting this as a practical recycling effort or anything more just experimentation. I've never heard of synthetic salt. It is a mineral that is mined deep underground from ancient seabed deposits or removed from large bodies of saltwater by the evaporation in big shallow ponds. Your fishtank salt in effect neither adds or detracts from salt already in the environment.Environmental problem?
If human filled up lots of the artificial salt into the oceans, the saltwater could be changed. The saltwater will end up but it's very long time because we died before it happens.Environmental problem?your salt wont even reach the sea

and it is so minute compared to all the other harmful chemicals dumped in ,probably one of the friendlier one in any case
