Bill B Posted December 6, 2020 Share Posted December 6, 2020 Can anyone tell me what this red stuff is and more importantly how to get rid of it. Picture is not good but it is fairly stiff and difficult to grasp and remove. It's also starting to spread more. Quote Link to comment Share on other sites More sharing options...
Timfish Posted December 6, 2020 Share Posted December 6, 2020 It's probably a Gelidium sp. algae. I would use H2O2 to kill it off. It is a bit tedious but use a syringe filled with 3%, press the end to the base of the algae and squirt out about 1 ml, move the tip about 1/4" and repeat. WHenever I use H2O2 the max amount I'll use in a single day is 1mm per gallon, I haven't had any problems with corals using that amount in tank. I wouldn't try or expect to get it all in one day.

Bill B Posted December 6, 2020 Author Share Posted December 6, 2020 Hi Tim, Thanks so much for your feedback. I was hoping you would notice my post. I spent a little time going through some of your vids hoping to see a glimpse of you, unsuccessfully. I am not usually very active but I feel like I have met/seen you sometime over the years possibly at an ARC club meeting?? Anyways, thanks.
