Great video Roland! Your system is really thorough- you can see it in your invisible water. Obviously your gorgeous fish are happy with their cone full of eggs!
Is that a coffee filter that your Purigen reactor feeds back into? Very clever!
One last question- did you make the egg crate platform your media is sitting on? If so how did you attach the legs? I have tried all sorts of things and they keep falling off!
Nicely done- thanks for sharing it!
