Hello, For many years I use pure RO watr in my tanks but I had only few chances to measure conductivity of my water. To change water in my 625 L tank I use long ( about 4m) plastic pipe connected with my RO filter in bathroom. Becouse my big Tank is about 1.5m above ground this occur increase pressure in RO filter. But I never thought about it…until now. Few days ago I bought conductivity tester and I checked water in both tanks (paros and geophagus). In geophagus (bigger tank) was 230 us and in paros was 130 us. I knew that my RO filter is old and probably I should change the membrane but I checked water directly from Ro filter and it was 25 us. So what increase conductivity in my tank? sand, roots – noo 🙂 It was this pressure… Today I will do water change in the old way….I will use two buckets and I will do few rounds between bathroom and my tanks 🙂 I will decrease conductivity in paros tank to ~ 25 us and next I will prepare 15L tank for one pair of my paros 🙂 I can’t wait…
About paros.. Now I often feed them with small dragonfly larvae – It is amazing to see how paros hunt for them 🙂 – In my opinion it is better food then moina – they don’t have hard chitin armor like daphnia and even bigger one’s are eaten without any problem. I know that this larvae are predators but I will not give them to paros during breeding.
Greetings!
