You have options for the top, though the best long-term solution I have seen is to rip out the metal mesh that comes in the top of both of those. Eventually, the metal mesh will probably rust on you. I will tell you what I do then I can suggest a "lower-cost" way that might work for a while.
1 the good way ;-) What I do is to, as I say, physically tear out the metal mesh using a flathead screwdriver and whatever other tools are needed. it's not a particularly precision operation. I just try to pop the little plastic pieces that hold the mesh in with my screwdriver and improvise from there. My goal is to just remove the mesh and the little bit of plastic used to hold it in. I like to keep the plastic insert that fits nicely into the top of the tank. I then silicone or hot glue a piece of glass into the top. I stop the piece of glass about 3 inches before the back so that I can hot glue a piece of mesh over that part as a vent. Make sure that the width of the glass is measured so that you can either swing the little tabs into place to hold it in, or push the little tabs in to release the top (can't recall which brand uses which system - just plan the glass so that the little clippy things work even after the glass is in). I should also say that before attaching the glass, I like to drill the holes for the Mistking nozzles. It's not as tough as it looks! Look up Pumilo's excellent video tutorial. I have drilled probably a hundred holes and only broken one super-cheap piece of glass. This is how I like to do all of my tanks.
2 an alternative :-) Another thing you can do is much less work but the results will not be as effective or as permanent. You can use the top as it stands and use one or two of these doohickeys
which are designed to work with default screen. This will handle the Mistking nozzle problem, but leaves you with - how do I manage my humidity with this big ol' metal screen on top of the tank. The "lower-cost" option would be to simply get one or two pieces of plastic wrap from the kitchen and put them over the majority of the metal mesh. I say majority because you want to leave some of the metal mesh uncovered to act as vents. How much of the top to leave uncovered by plastic wrap will be a work in progress, but it's all good because you can always just get more plastic wrap if you need to adjust :-) The stuff will cling to the mesh just ok at first, but you will want to spray it with a hand mister to get it used to sticking at first. Eventually, it will probably stick without spraying as much, but at first, you might need to spray AND weight it down with some little rocks or something. This spraying will hasten the rusting of the mesh, which is why I don't consider this to be a really long-term solution, but it will work for quite a while (hopefully until you figure out that the right way was the way to go all along ;-)
Forgot one more thing. Regardless of which way you choose above, you want your nozzles in the front, not the back. That way you can angle them at the back where you will likely have plants growing. I suggest using the top-back for the vents.
Best of luck,
