From my understanding, DIY chaeto reactors were the hottest thing to set up for a reef tank for the past couple of years. But with reports on how much of a pain it is to clean/maintain, as well as the risk of the LEDs cracking the tube and springing a leak..... I think a good number are moving away from this method and going back to the good ol 'fuge. So does anyone know whether this method has evolved (i.e. diff mounting methods for LEDs, known reactor brands that won't crack) or is it a declining, soon-to-be obsolete trend? Side note: I do recall @kinetic 's innovative build to prevent overheating, but also wanted to get a feel for what the community as a whole is trending towards. @kinetic if you see this, feel free to chime in on how its been working for you. Happy Thanksgiving Everyone!
