Although the juwel filter boxes arent the prettiest thing to have in your tank, i was thinking about filling the bottom with live rock frags and then putting a cheap submersible led light in and keeping some macro algae in. Not sure how effective this would be, hopefully qorth keeping the filter box.

Something like this https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F302104391800

If theres light for the algae and a moderate flow rate what could go wrong?

Im new to marine so any advice appreciated.

Cheers

Idea is fine in principle but wouldn't recommend using that light, I had one in my FW tank and it leaked within a month...

from experience with this one!!

  • Make a box out of darice mesh. This will stop most of the strands from walking into the return section of the filter box. 
  • You would need a 360* light IF putting the light in with the algae, else you will only get growth from one side of the light.
  • Your better off having a hang on breeder box with algae in and leaving the filter box with just carbon/siporax/phosphate remover.

Thanks.

I have an external filter so i can always remove the juwel filter box when considering chemical filtration. But im thinking it would be worth leaving the box in for macro algae/copepod refuge. Also pretty cost effective! Can you recommend a 360 degree submersible light?

Im not sure what you mean by hang on back breeder box either....

Nope! Don't know if there are any that are submersible!

these sort of things. I've ran one with a arcadia stretch fresh LED and it grew macro algae like a weed.

Looks like a good option, that way i dont need to deal with the juwel filter box and can remove it completely. Do these work using an air pump? Or would i need a powerhead?

either. they usually work on an air pump, but i connected it to a small eheim compact 300 and it worked flawlessly ( check my thread for pics )
