Hello everyone, I am just looking for some recommendations. I am currently building a 75 gallon tank and over the course of the last 2 to 3 weeks have been buying live rock for it. I started off with around 10 pounds in a tote with a powerhead and heater The next week I got another 15 pounds from my fish shop I should add. Just last weekend I found some live rock that had been broken down from someone’s tank on Facebook. When I went over to look at it, it seemed to like decent rock. The only bad thing is it had quite a bit of algae growing on it, and some of the pieces even had some GSP growing on it, he only wanted $85 for around 30 to 40 pounds of live rock so I figured it would be OK. I put all of it in the Tote together, thinking it wouldn’t really matter or that the algae would just die off. However, I’ve been checking on it every day and it really hasn’t changed any and today. A lot of the pieces with the algae had a saltwater tank smell to them and did not smell the best. I pulled some pieces out that were from the fish shop where they had no algae on them and they smelled fine but I’m just worried, if this will affect anything or if this is even OK to add into a brand new tank with my other live rock if anyone could put any input in on this, that would be great and I’m also looking for ways to scrub the algae off and get rid of the GSP if it is OK to add this to a new tank hopefully I did not kill all the rock that I know was good. And obviously now I know and realized if the LR I got off the person on Facebook had any hitchhikers or anything on it it would more than likely transfer to my live rock from the fish shop so I’m just looking to see what everyone thinks.
