I have a large piece of driftwood in my tank that has been running for 5 months. I had algae issues as it was becoming established and it seems to have come under control. The other day I removed the wood so I could vacuum everything really good and scrub it down and I had to retie some plants anyways. So I rinsed everything off while it was out. I am assuming that was a bad idea. Two days later there is some white fuzz on it which searching the forums looks like its some kind of fungus. I take it in the future I should not scrub or rinse the driftwood! I guess I just gotta brush it off and hopefully it goes away in a few days. Would adding salt help?
