And there are probably very few, in the hobby, that have the expertise/hardware/inclination to find out.
One thing I was thinking - GFH, as it's name implies, is wet, whereas GFO is dry. What if it (GFH) went through a period of incorrect (whatever that might mean) storage - let's say in a warm climate? Is it possible that some bacterial (or other) contaminant could grow using the hydroxide as a medium? A rhetorical question, of course, but could some bacteria or mold, serve as a growth accelerator for algae?

... How do you like dosing? I only ask because I have been thinking about retiring my reactor.
You hit the problem on the head! There are so many possibilities. We just don't have the means to determine what the real cause is - if any.<a href=showthread.php?s=&postid=15536042#post15536042 target=_blank>Originally posted</a> by luther1200
Could be, or I also thought that since ROWA has to be rinsed so much that maybe its very hard to get all the fines out. And even if the water looks clear it might still have some trace iron in it. And maybe that trace iron could be fueling the algae. But that was just an thought I had. I have no proof or anything to back it up. But probably unlikely anyway, because people dose iron for the fuge's and aren't reporting algae out breaks from it. I would like to ask a chemist if either is a possibility.

Seriously ... it makes it very easy to maintain my supplement values within narrow (IMO) limits.
Alk is always 8.3 dKH +- 0.2 (LaMotte)
Ca stays at 440 ppm +- 20 (Elos)
Mg stays at 1350 ppm +- 50 (Elos)
When one of the values starts to stray, I just add or subtract a minute or two to the dosing time. Lately my coral growth has taken off and the tank needs more supplements. Dosing makes it easy to maintain the values. I'd never go back to a Ca reactor. I've read some say that dosing is inadequate for a large tank. My current total is approx. 350gals and I have no problem.
I don't have any experience with Phosban, but if it's wet it's very probably hydroxide.<a href=showthread.php?s=&postid=15617744#post15617744 target=_blank>Originally posted</a> by Reefun
Is Phosban Iron Hydroxide or Iron Oxide ?

Does the HC actually worth the
money? How much do you put?
