so I just plumed a water changing system from my fish room to my 2 tanks. so now I need to plum the old water out. So my question is do I just send it down the drain in my sloppy sink and then to my septic system or drill a hole in the house foundation and plum it out side? Will the bactria in my salt water affect the septic bactria? I have a 240gal and a 150 system so there will be a fair amount of water going somewere .also out side, where is the best place to drain the water. saltwater will kill grass and trees right.
Thanks Curtis
