1.Dont be a fool and use tap water best is RO water or filter and yes the prexoide (it'll eventually gulp up green seaweed in the lines any way, we'll get to that.) 2. Definitely place it in a open a ft away from anything for good circulation and remember dusts builds up on flat surfaces when they tired of flying around, exhibit A. you'll notice the metal vents are clogged of dust you can pry that out and really clean the radiator under it with a tooth brush and micro fiber rag (for the 1.5 years plus users check and maintain for cooling to be more effective. 3.A. exhibit B. Is for anyone that might complain with one side not working properly due to overtime unfilter water in the hose which turns into seaweed "can't simply just add water for 2 years plus and not expecting something to grow in there, tap water isn't consistent, it's like a box of caramel pop corn with a toy you know you getting but no clue which". Use these tablets turns the water blue and 1000% resets the inside layer and hose clean I'll recommend prime with it and use once over night and next day simply replace water and wipe down the hose on both ends. MAKE SURE TO USE EIGHT SLEEP TOOL AND DRAIN HUB ALSO TILT A LITTLE SHOULD'nt SEE ANYTHING THEM PILLS DISINFECT AND CLEAR THE LINES.

I'm not sure how much they cost as you probably only need to have 2 a year for let's say 5-6 years before the top layer might catch a rip and then leaks"THERE'S A POST SOMEWHERE THE GUY OR WOMAN FOUND IT AND REPAIRED THE LEAK. The top layer is a work of tech as you can literally fix that cell and water still flows around to where it needs to go just good luck finding it.

I think that's it.
