Frag tank lids? Yes or no?

[ReefRondo]

Hi guys, I have a large frag system and have glass covers for almost the entire top except a small section towards one end. Day one of fish and one of my wrasse jumped and I had the lids already so slapped them on. I am aware that these lids unless kept exceptionally clean (which I do daily) will reduce light levels getting to the corals. Do you have lids on your frag system and either way what is your reason? I am considering removing them to enhance colour and growth although I’m not sure what to expect. The amount of water that collects on the underside is unbelievable so I quite like the thought of it all not humidifying the room and having to use more of my ATO tank. I think the amount of water collecting on the underside of the lids will be reducing par quite a lot on its own. I lift them and angle them to allow this water to drip back into the tank once or twice a day.

No glass lids but ill do mesh lids. You want that gas exchange for the ph

If the light level is reduced by the lid, measure the difference and turn the light up?

fine if you have a skimmer tbh

I'd vote mesh for less cleaning over glass. (Also more gas exchange but that may not be an issue for your setup)

I’ve ordered a Redsea mesh DIY top and will give that a bash.
