I added belem and DIY CO2 a few days ago. Otherwise no changes. No pictures as I cannot remove the cloudiness even with fresh carbon and Purigen. I imagine UV would work but I'm not paying that much.
Yeah I was about to ask about the belem because I remember reading your post on the swap and shop. lol.
I added some carbon to my 60p and its working wonders. My water is pretty clear now, kinda...At least my water isnt super yellow when I wake up. lol
