Re:fry tank

i had made for me 2 intank nurseries should i be lucky enough for my seahorses to have fry. I have very fine holes drilled in a number of places thru the acrylic and a very small pump at 1 side to help water movement. My question is i want to put some sort of mesh over the holes so the baby brine cannot escape into the main tank. I am planning on using some form of adhesive to hold the netting. My question is does anyone know what type of netting would work best and where to buy it as well as what type of glue or adhesive will work and not harm my tank. would the same type of silicone for sealing aquariums work and would either nylon stockings cut apart or perhaps screen mesh used for screenprinting do the job. Appreciate any help Also, the intank nursery is 17 inches long, 4 inches wide, and 8 inches deep. will this work ok.it will hang on the front of my 90 gal tank. one on each side.
