adding plastic screen to HOB- anyone else tried this

[middave]

I have a 65 gal reef tank with two HOB filters- used to have a small sump, but had an overflow issue so i got rid of it.
To help with export of nitrates I put plastic mesh screen where the water flows back into the aquarium, at first to
quite the noise, but I found that it was a great place to grow algea, it kinds of acts as a turf scrubber and you do see the algea
from the front of the tank I was wondering if any one else has tried this and is anything negative that could happen, There is very little algae in
the tank. I would just like some feedback

I had something similar setup on a 45 gallon that worked well. Had a big HOB with 2 chambers left the lid off of it one side had live rock rubble and some marine pure chunks and the side getting more light I cut some pieces of egg crate to slide down in there that ended up coated in algae. Other than one wavemaker that’s all the tank had and it did really well used it as invert/coral QT tank when I broke it down there was loads of things living in that filter
