I have similar problems too. Thinking my RO is spent although I haven't had a chance to borrow a TDS yet to confirm my theory (bought a new membrane and prefilters anyhow since it's been >2 years so the membrane has to be due anyhow). Most pieces are fine but 2 or 3 pieces just seem to be plaqued with some kind of slow recession. Very annoying/disappointing. I think I might try the phosban next. I figure the only way PO4 would be getting out of my system is via the little bit of caulerpa that I try to prune back, or maybe into the mangroves (but those things are soooo slow growing that can't be a viable method of PO4 reduction).
Brad what did you do to treat your red bugs? (Is there a thread that my short-term memory has forgotten about?)
I've also been wondering about reactor media, I've only topped up my media over time, which means there must be some old media down near the bottom of the reactor ...
