Yes, I just went to HD to get the window screen stuff (frame, corners, spline, spline roller), and I bought the 1/4" clear netting from BRS.

It was a bit tricky to get the netting tight, but overall it worked great and looks good. Doesnt block any light at all on my 29gal LED frag tank.

Canadian Tire Garden section is where I found my screen, 1/4" but 50' roll for like 10.00 this one is 29 x 16"

Pics are blurry but gives you an idea about what to look for .

I used the plastic chicken wire you can get at canadian tire .....my diy skills impressed the hell out of my husband who was expecting my usual bubblegum and masking tape kinda job :lol:

I guess i should look into this, I just found my flasher wrasse as a dried up piece of jerkey behind my tank :( Not bad tho, first jumper in 4 years.

yah, screens are definitely the way to go, I've lost two cleaner wrasses and a mystery wrasse through light diffuser. I also lost a Labouti wrasse because it was strong enough to knock the cover clean off the tank.

If there is only one awkward angle of approach for them to fit through the hole, they will find it.
