I currently have a little breeding box that is a bit like a HOB on my Juwel tank. This means the front flap on the lid is open a little and I have been surprised by the amount of water I have lost to evaporation.
I am considering an open tank in the front room and was wondering about evaporation. As I understand it, only the water evaporates leaving behind all the minerals etc. So if I replace the evaporated water with tap water my GH would slowly but consistently rise?
I see lots of posts on shrimp forums about only topping off with RO but haven't really seen this mentioned on aquascaping forums.
Is this something I need to consider or just top up with tap water and don't worry?
