Old Saltwater to culture Brineshrimp and Phyto and Rotifers

[themastr]

I live in an acreage and far away to always get salt. LOL
But my main worry is I can't dump any of the old saltwater in my septic tank it will kill and rust the pump and all the bacteria needed to work properly.
My tank volume setup is about 350 gallons going to be 450 Gallons. So every water change is a lot of old saltwater. I usually just put it in the yard somewhere but I was trying to not kill what little grass I have left. LOL
I will probably just buy IO and use that I was just hoping that I can reuse the old saltwater somehow instead of going to waste. I waste enough water using R/O for the whole tank. Good thing water is from a well and FREE minus the energy to run the pump.

If anyone else has experience I would love to hear from you.

thanks

I wouldn't worry about the salt in the water going down the septic field. Been doing it for a while and haven't had a problem. You put way more toxic crap down there than that. Think toilet bowl cleaner, bleach, etc. Your old tank water is loaded with beneficial bacteria that won't be affected by the field.

The amount of water daily life uses will dilute the salt more than enough. Showers, toilets and dishwashers will run more than enough down the line to dilute and take care of the problem.

If your really worried about it, pour your change water out on the drive way, eventually there will be a large enough salt build up it might keep some of the weeds down. That is going to take huge amounts of salt though.
