No worries. With good info people can make good decisions...
I will try to keep a few Scopas Tangs and see what happens.

Yes, I felt the same way and I spent a lot of $$$ on that High Capacity GFO for a few years. That reactor was such a pain!!!

I have not stopped dosing and regularly check my phosphate. It was 0.02mg/l this afternoon. Phosphates are a result of decaying organics... from uneaten food, dead creatures and decaying algae. If there is life and death there will be phosphates. Kinda like taxes... no getting away from it. LoL.

That is a great use for it due to it's low cost. You can remove all the bound up Phosphate in the rocks by just letting it leach out and then removing it with the Foz Down. No need to keep doing lots of water changes but just remove it slowly.

With Foz Down you can remove all bound up Phosphate from the rocks. Once however you start feeding the system and life resumes there will be new phosphate created that will need to be removed from the water via Foz Down. So the answer is Yes and Yes.

With Lanthanum it is possible to reduce Phosphate down to 0.0015mg/l or 150 parts per billion. My experience is that I can get the Phosphate levels low enough in the system that I do not need to rely on other methods of Phosphate control. I only use Foz Down in my system.
