AL99 - Triton method phosphate control

[Robert's Reef]

Hello, I've recently switched from BRS GFO High Capacity, https://www.bulkreefsupply.com/brs-bulk-gfo-granular-ferric-oxide-high-capacity.html, to Triton's AL99, https://www.bulkreefsupply.com/al99-phosphate-remover-triton.html, for phosphate control, (I'm moving toward the Triton method), and it doesn't seem to be removing the phosphate from my water.

The current reading is .26ppm, whereas before it was .04. The RO water used for top off reads, .02 ppm phosphate. My feeding habits have not changed since the switch over. I have increased the amount used for my 100gal tank, from 250ml to 375ml. I've tried increasing/decreasing the reactor's flow. The most it has ever done was maintain the current level, and never decreased it. My reactor is the BRS GFO-Carbon Reactor deluxe, https://www.bulkreefsupply.com/brs-gfo-carbon-reactor-deluxe1.html.

I've cleaned the sump and protein skimmer and I replace both carbon and GFO every two weeks. I continue to change my filter sock twice a week.

Any ideas on what could be going wrong?

Thanks, Robert

I am also very intrested in the results, because Triton is recommending use of AL99 in my system as well. Like you, I am using BRS GFO along with BRS 0.8 carbon in my reactor. One problem I noticed with the GFO/0.8 carbon combination gets clogged very quickly....withing 7 days even with medium tumble.
