I've made one out of the AquaClear 70, its pretty simple,my only regret is that i wish i went the 110 route.
Here a few pics
its filled with a little bit of live sand, Some LR rubble and Chaeto, teeming with pods, and bristleworms
but because My tank is new, Up since Feb, i'm still having a few algae outbreaks, a few diatoms, and Hair Algae, verry little but I freak out anywayz, Any Idea when it will go away?
Finished Product
what was once a 3 inch ball of Chaeto, has now completely overfilled the fuge
The fuge is lit by a simple desk lamp.
I had first slowed the flow, by breaking the impeller, from 6, to 3, a slower flow means more contact time with the water and Macro Algae.
I had then, taken the media basket provided, and used it to create a Baffle, to Guard it from the impeller, and siliconed it in place,
The Plastic Screen Guard/Grid Was then used to cover the waterfall?/overflow into the main tank, to keep the chaeto inside.
I had also cut the U-Tube so that i had a better fit in my tank
Allow 24 hrs to dry, and ur ready to use
