Which blocks the light more?

[lietz06]

I need to cover my tank bc I have a midas blenny and don't want him to be a carpet muncher so...does eggcrate or netting block the light more? Thanks

That would really depend on the type of lighting you have... and the type of netting (the coarseness ). If you have florescent lighting, I would venture to guess that the eggcrate may suit you best (if you have several lamps).
If you have a single point light like metal halide the netting would probably be a better choice. Netting with larger holes would be better than something like screen with very small holes.
Sorry to sound so ambiguous.

I have t-5 lighting....it's 12 bulbs I think.

if you have T5 then i would do eggcrate since it is much simpler than making a frame for the netting. i have a MH and have to do netting since the further the light source is the more light gets cut off if i were to use eggcrate. since your lights are much more dispersed the eggcrate will hardly make a difference. but netting is always the better choice if you want maximum PAR to reach your tank.
