I think that a hardware store test kit may be insufficient. Red Sea makes one.I truly had no idea that was a source at all thank you again. Would prefer Coral skeletons for a whole lot of reasons mostly because I feel they work the best for biofiltration and I know anything that could brake down from co2 etc would be good but probably pony have enough for one or two tanks.i am going to get a test kit for iron from the hardware store as soon as I can so I can get to the bottom of this.
