When i water change my freshwater tanks I just go and dump the water on the garden, but this is obviously not an option when the water contains salt. I dispose of brackish and salt waste water by chucking it way up the hill where nothing grows anyway, but you can't do this when living in an urban area. So how do brackish and marine hobbyists get rid of the salt water waste in suburbia? I ask because we might be moving soon and you can't put salt water in a septic system because it will kill all the bacteria.

Thanks!
 
all of the drains in our house drain into the local sewers so we dump the upstairs tankwater into the bath and the downstairs tank we dump into the stormwater drain that is in the back garden.
 
I used to dump it on the lawn and never had any problems with the grass dieing. Probably due to the small amount of seawater (less than 200litres every few weeks) and the lawn being water twice a week with bore water. The fresh water simply washing the salts through the soil into the ground water table. These days I just pour it down the drain and it gets mixed with the sewerage waste water. Again the amount of salt water is tiny compared to all the freshwater in the drains.

If you pour it on the garden/ lawn, then just tip it onto a different area each time. The amount of salt will be minimal and shouldn't affect most plants. If anything it might help to buffer the soil PH and help prevent acid soil caused by excessive fertilisers.
 
Down the drain! and for my reef tank same thing, but sometimes when I do a big water change I just dump it out into the lawn.
 
Just dump mine in the garden on the grass, never had any problems.
