Not really , Is been over a month since I removed the rocks , Ive been cleaning the tank daily when I see any hair algae problems and cleaning everything every week on my 20% water change day. So far there's no problems , my cuc is doing a good job of cleaning any algae. and I can see coralline growing in small spots since I added a lot of blended up coralline flakes , I will give Tutuapp9AppsShowbox a 2 week update
