To cover or not to cover, that is the question.

I have 2 mixed reef with fish tanks. I am tired of fighting salt creep. Should I remove the covers? Any pros or cons to be worried about?

screen cover?

A few days ago, a clownfish in my tank got spooked. He jumped up, hit the screen and bounced back into the water. Without a lid he might be dead. This was with me around, I have to assume they do this when I am not around as well.

I lost two sixline wrasses before I got a cover. Mine was good for months and months except one day he jumped. I got a replacement and 3 days later it jumped.

so you never know lol.

If you have fish that are known for jumping, then I would leave the cover on.

Having a lid also saves money, because there’s a lot less evaporation. Also if you remove the lid, it will make the room a lot more humid.

Depending on how stocked you are in a reef tank, evaporation can be extremely helpful if you use kalk and not a calcium reactor. Having 4 wrasses carpet surfing, including the guy in my picture. My tank keeps covered. I need to make it a habit so I can have my wrasses again. I have a canopy to cover the mesh screen. So, a cover for the cover.
Cons are more evaporation and fish jumping out but looks alot cleaner.

I bought a bunch of screen door framing and nets and made my own covers that are super low profile and mixed in with the top of the tank. I don't even notice them, and the screen is wide enough that I can pour pellets and additives right in without removing them.

Where did you get a screen cover? What is it made up? Does the salt eat it?

brs also sells screen kits. With a decently stocked hardware store you should be able to re-create exactly what they have.

I agree screen covers are a good idea if you’re worried about jumping. Red Sea net covers are really good.

The Red Sea net cover kits are great. Make sure you order enough zig zag kits to go around your light mounts, and anything else other than a standard single overflow box. Take your time rolling the screen in or buy a better quality screen roller tool. The one they give you cuts the screen (basically, thinner diameter cast net monofilament). Try to leave yourself a do-over patch of screen if you have enough so if you cut it you can just slide it up a half inch and start again. I wish they had these kits when I started years ago. It's actually fun to watch my habitual offenders rebound off the net like a trampoline!

100% get a lid. fish will eventually jump, not a matter of if. sleeping and getting startled by any snail/invert will cause even calm fish to jump or get spooked. dont lose 200 dollars in fish than get a lid.

I had a clownfish jump out in the late evening. Don't know why and I didn't spot him until the next morning on the floor. A damsel was spooked by a new fish I put in the tank and jumped out right in front of me. I was lucky to be there. I am a firm believer in having a lid after these episodes.
