I suppose your right Big Country74. Its a fowlr and my nitrates are running about 20-30 right now. I added this as an experiment to get experience with it and see if it drove down the nitrates. My phosphates of course right now are undetectable with the api test I have.

Thanks for the article. Very interesting read. So it appears it does add ferric iron but, in a particulate form not soluble.***I also didn't realize it has a negative affect on the alk in the tank. I have struggled with this and have tried using a product my lfs sold me by Red Sea called I believe, coralline enhancer which raises the alk. Just ordered some kalk from brs which will be here today.
Only I'm still trying to wrap my head around whether I will need to use something else to get the alk levels up to say 8.5 to promote growth. It is my understanding that kalk is used to maintan the levels you currently have. Maybe I have that wrong.....
My goal is to get the tank to a state where I can start trying a few beginner corals.
The tank itself has been up and running for 2 yrs.
90 gal display
20 gal sump
reef octo skimmer
brs dual reactor w\gfo and carbon
about a total of 80lbs of LR between the sump and display
reefkeeper light controller
mag 9.5 return
4- sicce model 3 powerheads for flow.
brs ro/di 5 stage
oceaonic salt mix
recent test results
ph 7.9-8.1
sal 1.26
cal 520
alk 7
nitrates 20-30
phosphates undetectable
just got a mag test kit so need to test that.
Bio load is fairly small right now. And before you say it, some of the fish I have will be traded for reef safe fish as well.:twitch:
Dragon Wrasse
Niger Trigger
perc clown
blue damsel
misc inverts-herms, snails, conchs
Next big expense for me will be lights. I'm currently running a retro-fit kit of 2 96watt compacts. So only 192 watts of total lighting. Bulbs are about 2 months old.
Tank in general looks pretty good other than a little cyano that comes and goes.
Can't think of anything else and I realize that was long winded but, thought I'd share the info for insight.
Thanks everyone. I welcome any thoughts on anything I mentioned.
