I was testing my water today and found out my shrimp tank TDS is over 700!! Is this harmful to the shrimp? I am going to start getting RO water now to try and lower the TDS. I have at least 5 berried females. Is the high TDS harmful to the babies?
Not sure what my GH or KH is, but my KH is low as I have to have crushed coral in all my tanks or my PH crashes. I also have peat in the tank to get the PH a tad lower. GH is at a decent range at least last time I tested it was. I don't use any ferts.
You'll likely find high GH as well. Don't reduce the TDS in one shot, do it gradually or you might kill the shrimps by doing so. Problem with high TDS is molting issue, that kills shrimp much slower than TDS shock (say, from 700 to 200 in one WC).
Yeah, lower it slowly, like mentioned, do a 10% water every other day with distilled until you at least get to the 260 range at the most. 400 TDS is straight from your tap??? Because that is above what federal regulations says is acceptable for drinking water. Unless you run on a well or something.
