Foz Down vs: GFO

Yes I am very cautious when mixing a new solution. shoulder length gloves, eye protection and gently stir it up outside. I still may choose a different approach in the future because i seriously suspect the iron in GFO fuels algae even tho measurable phosphate levels are low.

I keep switching back an forth but i think I'm going to stick with Foz down. As I dose vinegar it keeps my phosphates under control and every time I add even the smallest amount of GFO it completely wipes out all phosphate in my tank (0 on a hanna) and I notice pale corals. I like that with a small amount of Fozdown I can control how much I want to lower my phosphates by.

Im planning on only using it on my new 90g. I guess its ok to use with Prodibio as I use go with it now?

I also only dose Fozdown directly into my filter sock to try and avoid any deposits making it into the tank. Don't know if it makes a difference or not though.

From reading, depends on the sock, seems 100 microns to coarse to be effective.

Prodibio and Foz Down are compatible.

I have 5 and 10 micron filter socks with a 4" plastic ring available.

So you need a finer than 100 micron sock? God that would clog so fast on my return.

If your concerned about removing the flocs yes. I am not concerned about it and let them settle out in the sump. I vacuum the sump so any would get removed then.
