@eMCRay what direction do you have the fans pointing? Pulling outside air in, or vice versa?

Pointing inwards / down. Since there is about a half-inch gap between the fan and the top of the viv, it will recirculate a nice mix of viv and outside air - and I can then also cover up the vent from the outside to control it during the drier months.

Of course I do - wouldn't recommend them otherwise.

Here it is attached to a fan (I sealed up some of the extra gaps with silicone to avoid thumbs getting any stupid ideas or dirt / FFs making it in). Works great - and in many cases have been running for a few years. They obviously last longer if you seal them up like this to avoid dirt or feeders clogging them up (but I can still take them out and swap them if I needed to).

Here is the same assembly in a thumb viv. I attach it to the top beneath a cut-out / vent so it can circulate a nice balance of outside and inside air. So 4 total of these filters for one viv - two on each side of the fan assembly, one on the outside of each vent (I use two). The huge benefit of this is that I can manually control how much outside air is taken in by partially covering up the vent.

This is the "intake" / re-circulation (sometimes the frogs even climb all over it if its more humid...).

Here is the outflow.

It's also available in different sizes - here is a 20 or 25cm version in one of my larger builds (with geckos, hence the bamboo).

What fan is this? And for one tank do you need two different fans? I also have no clue how I would cut them into glass

Just one fan on one side (to keep a nice diagonal airflow with some pockets of moving and some less-moving air).

4 of the filters (2x for both sides of the fan and one each to close up the vents from the outside).
Fan I used Evercool 80mm x 10mm Fan (EC8010M12CA) - FrozenCPU.com (tried to keep a low profile) - you can adjust the size based on the size your viv; they can get quite large - I've used the 80mm, 120mm, 140mm and 200mm.
Filter: ModRight FilterRight 80mm Clear Aluminum Fan Filter - FrozenCPU.com

The picture I took is from a 1/4 inch custom acrylic build, so it's a bit easier to work with (and lighter) - my own design that I might post a design & build log on soon. Downside is that it scratches easier and can warp at high humidities if it's too thin / not reinforced properly.

You can cut glass (and I've done it too) with diamond hole saws (like 15-20 bucks at home depot or amazon). Here is a good tutorial (and wear leather gloves / eye protection):

For some reason this part made me laugh so hard 😂

This is a wonderful flow chart for newbies! Thanks for this!

Well done! The analyst in me loves an explanation via flow chart. I've been gathering information on this site for weeks, and this chart summarizes everything a newbie like me needs to know about creating a healthy environment. I wish I had noticed it at the beginning of my journey. It's a perfect launchpad.
