That’s such a big job it really is, a thorough cleaning. It doesn’t look that bad above
If you can stand to just direct siphon and remove any growths daily, could mean up to 2-4 gallons a day picking off growths with a long hose and stilled tank, that raw mass removal over and over harms the communal benefits of those invaders, you might can exhaust / it already looks like a weak invasion. The rip clean is safe we can show in pattern, but hideous effort to do it right lol. It would be nice if simple repeat directed siphon worked here.
*additl cheat alert, the Amazon $150 55watt pond sterilizer.
if you hand remove those growths, plus cheat burn with uv, this is possible, we used uv to hammer jakes dinos. Hidden joker card cheat.
I have now been keeping reef tanks for over 30 years and over that time I have seen fads and techniques come and go and I have been asked questions about just about every aspect of the hobby.
