Hi all.
Got my Reef Factory Smart Tester up and running and I have to say I’m impressed. The app works well, the instructions weren’t straight forward but it seems very reproducible.
Now that I can keep a closer eye on my PO4. It seems to drop rapidly when I replace my granular ferric oxide (GFO) because obviously it’s got fresh absorbent material.
It hangs around 0.1, then over a week or so it slowly rises to around 0.15.
I’m now playing a battle where I’m worried about feeding the fish and keeping the PO4 stable. When would you change the GFO, how much would you change? (I’m thinking change half, to avoid a total shock).
Other than this, when running a high stocked tank, how do you reduce PO4?
Can I add more ceramic material to allow for bacteria etc?
I have wrasse and clams so reluctant to use Lanthanum.
