Hello friends, I have some dry rock that I received from my local fish store and I smash them up and glue them together and I had them sitting in a bucket of RO water for two weeks just to get all of the Dust and particles off them. Today when I went to go take them out and add them to my aquarium, I noticed that they had red streaks and red dots on it. Please see picture. Can someone tell me what this is and if I should not put it into my aquarium or what I should do? The rocks have been just sitting in a bucket at the store for months on end, definitely not live When I got them. I also have a 75 gallon FOWLR. I’m wondering if the solution is just to let it stay outside for two weeks or so to let everything just die off?
