So I have a question. I just did a 10% water change and my TDS is 240. TDS of my salty shrimp RO water is 200. My question is if I'm aiming for less that 200 and I'm putting in 200 wouldn't I either need to change more water (which I can't do) or use less salty shrimp mix? Thanks

Yeah i have been using the Spreadsheet but i was wondering of adding water that had no minerals would stress the shrimp or not? also because you recommended to do it before i was wondering how often it could be done or does it really not matter? Duckweed wise i've kind of left for the time being, although its not growing as quickly i'm kinda experimenting to see if it gets rid of Nitrate as well as it gets rid of Nitrite.

Just taken these photo this morning of all the shrimps I have, except the Blue Bolt. The mother shrimp has brown/grey egg.

So its been a few days and the baby's are getting bigger by the day. I'm still thinking im going to get 10 more RCS at the beggining of the month simply because Im only seeing between 3 & 5 adult shrimp and 2 - 6 baby shrimp at any one time, so im worried that:- 1. my colony will take ages to mature to a size I'm happy with 2. over the course of 2 years or so i may start to get problems with genetic's and start to get deformity's especially when I've got my 2nd tank set up and I'm doing culling in my main tank. 3. so i can test drip acclimation properly so i am better able to do it and can advise others. although i haven't read all the readings, i have just checked TDS and my tank is reading 290. i made the agreement with my partner that i had to get the TDS to below 250 to get the shrimp, can i do a 0TDS water change? and if so how often can you do that 1 in 3 or what ratio? What action can i take if the TDS, dKH & dGH are miles out?
