I've always had open top tanks.
Does euro-bracing help with jumpers? I really want a blue spotted jaw fish (a known jumper).

lol Pedro, that tank 'cover' (and I use the term VERY loosely!...lol) was what I put over my tank (knowing I have fish inclined to jump) at about 3 AM after a very long day during my last upgrade.
This is what the finished cover looked like for that tank ..
After having my Royal Gramma jump through egg-crate (has too large an opening for many jumpers, and seriously interferes with lighting getting to the corals) right past me, I'd decided something else was needed and came up with the cover design you see in the pic. I haven't lost a fish due to jumping since, nor does the netting material interfere with lighting (the use of the acrylic edging doesn't throw a light limiting shadow either), nor does it become brittle over time
Regarding pros and cons of solid covers - IMO there are only cons in using them. At best, they may slow evaporation but then you are also retaining more heat in the tank. Not worth the trade off IMO. Add the effective of reducing what lighting enters the tank (think of the $ you are paying for that..) and the reduction in gas exchange (important!!) and they become a lose-lose situation.
