This chaeto refugium basket has been running on my biocube 29 since 2014. I work with plexiglas well, so I made a media basket and refugium basket to fit side by side in compartment 2 of the AIO. Some people will say you don’t need a basket, I included one cause I wanted to force the water to go through the chaeto instead of taking the path of least resistance straight across the bottom of chamber 2, and into chamber 3, where the pump is located. This basket works like a chaeto reactor, water comes in through the bottom after leaving the media basket, and comes out the top on the opposite side. Then down and out the bottom to chamber 3. You could see the solid chaeto brick that it produced. As far as lighting, I starting with the JBJ light(4 white LED’s), mentioned above, on 24/7. At first I had it on the back glass, but the chaeto turned pale and soft closest to the light. I ended up mounting it with Velcro strips to the back wall, and this seemed to make it grow really good. Finally, after 6 years of constant operation, the JBJ stopped working about 1 month ago. I ended up buying the Smaller IM Chaetomax, and stuck it directly on the back glass. The chaeto is growing beautifully like this with no paleness. I like this one a lot better. Plus, before I had white light scatter coming from behind the tank. Now there is less light scatter from behind and a beautiful pink glow from behind. I haven’t taken pictures with new light but I can add tomorrow.
