Hi there;

Despite the manufacturer's claims, What's your experience with phosban? Does it leech out the PO4 back into your aquarium? I had consistent readings of 0 and today I tested 0.25. PLus I have some hair algae, dino and cyano. Not a lot, but enough to make me do some water changes and question my phosban. I run it on a mesh bag close to the chiller's outlet.
