Thread: curing dry rock

  1. Default curing dry rock

    0 Not allowed!
    I started curing my Marcos dry rock in a separate stock tank with rodi water and noticed my tds were at 024 ppm is this normal? will it eventually go down in time? I do not want to add to my tank just yet.

    I'm not a 100% sure but I think boiling rocks is the way to go? And these a test you can do with vinegar, drop a little bit on the rock, if it fizzes it will change the ph in ur tank. Dunno if that helps? I can try and find the article about rocks and wood I found if u like?

    When it come to natural formed ocean rock used in marine aquariums, the vinegar test is useless as the rock will help to increase and maintain your pH at around 8.3. Same effect as crushed coral in that respect.

    It is normal for your TDS to increase a bit as the rock will naturally leach out mineral like calcium into the water. I personally would be more interested in seeing the impact on your nitrates or phosphates. I would suggest getting a FW test kit and see if there is any impact yet.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Yes, ditto what Cliff said. In saltwater, you want the rock to boost your pH, it helps maintain the water parameters of which there are more and different elements than what you watch for in freshwater.
