Is this Phosguard exhausted? I did change it out of my filter, but could it have gone a little longer? The Salifert test is showing almost zero blue. Thanks all
I would pull it once it turned that yellowish/ brown color. I’d say you pulled it at the right time. Phosguard tends to leech back in once it’s sucked all the phosphate out. Hope this helps!
