Patrick M. Bodega Aquatics Posted January 12, 2021 Share Posted January 12, 2021 Hello! I have about two gallons of rocks I picked up at the beach last month I set it up in a biorb flow 4g without any fish up until now. I am planning to get an alien betta and a few ember tetras for the tank and I was wondering how I can make it safe for fish. The rocks have been soaking in the tank for about a month now and I would obliviously drain it before adding the fish. Thanks in advance! Link to comment Share on other sites More sharing options...
CanadaAmanda Posted January 12, 2021 Share Posted January 12, 2021 If they've been soaking for a month, and the tank isn't growing anything weird, I'd say you prepped them. Link to comment Share on other sites More sharing options...
MAC Posted January 12, 2021 Share Posted January 12, 2021 I collect beach rocks all the time for my aquariums with nothing more than a rinse under hot water to clean any sand/debris. If you aren't sure what type of rock of what the rock is made from you can take a bucket, test the water hardness and ph to get a baseline and then soak the rock over a period of time and test again to see if it is adding anything to the water.
