Screen top question

[reefpeeper]

I have a 34g rimless deep blue and want to make a screen top so I can keep some gobies. I see bulkreefsupply.com sells the screen but they have two sizes. Should I use the 1/4 or 1/2 inch screen? Which have u guys used?

Definitely the 1/4", many smaller fish can get through the 1/2". Light loss is negligible with either so no reason not use the smaller netting.

Thanks. That's what I was thinking

1/2" let's a lot of fish out, then they can't get back in.
