Are these sea rocks safe for a freshwater shrimp tank

Recommended Posts


Hello i'm currently on vacation at the sea. 

I have 2 tanks currently devoted to snowball shrimp and blue dreams. I would like to start setting up my 100L tank (freshwater) for another kind of shrimps, so i found these pretty cool looking rocks next to the sea water. I know i still have to clean them and test with vinegar (which vinegar? Apple or alcohol?)  but could anyone possibly tell me if any of these are good or not good to use just by looking at them...

Difficult to tell just by looking at them. 

Some of them look like limestone which is not good for shrimp tanks.

Test with White vinegar.

If you have a Nitrate test kit, use reagent #1 to test rocks. It's an acid and is strong then vinegar.

      Oops did I mix them around?

      Ok then. Will add more plants to try and reduce nitrates.  Thanks Simon and JayC for the pointers and hints. I think the Dino Spit is the Glutaraldehyde and the Dino Pee has the macro and micronutrients. I will leave off the Glutaraldehyde and reduce the dose of the Pee to one third. I am pretty careful with the dosing.  Good news is that there are at least two RCS females still in the tank and looking well. Maybe they went and hid and moulded after the big water change? The surviving  DAE are all looking well.  Anyway will take all your advice on board and do smaller water changes and work out a dripper system.

      jayc's comments on letting remineralized water sit around got me thinking.  I've had pre-mixed up batches of water sitting around for a month or more with no obvious growth.  I asked the Salty Shrimp people about this, but unfortunately they replied back to me in German, and google translate doesn't seem to work too well.  So if anybody knows German, here is their reply: " prinzipiell ist es kein Problem dein mit Bee Shrimp GH+ aufgesalzenes
      Osmosewasser zu lagern, jedoch werden dabei einige Spurenelemente
      verloren gehen. Dies hat sich bei unds allerdings noch nicht als negativ
      herausgestellt, da wir selbst meist eine Menge von ca. 1000l aufgesalzen
      parat haben. "

      Even though this isn't the acute cause of your problem, the nitrates are too high.
