I have been running a turbotwist 9w on my 70 for a couple of weeks now and I have been fighting with keeping my trace iron up or even a reading at all. If I test my 15 tall with florabase no problem I always get a nice reading around .2, my tap water is about .1 btw.
Now I have read that uv steri's might oxidize trace elements , anybody have any real proof? Since I turned it off
I have been able to keep a measureable level around .1.
I got the uv because of a Jobes inspired green water outbreak. Maybe it was a trace element crash that helped ? I 'm stumped , I thought it was the test kit but It works well on my other tanks.
I dose using pmdd minus the nitrate which I don't need. I have had to start dosing iron using some kent iron supplement I had and I was already dosing massive trace.
Am I crazy or is the uv really screwing with my trace?
Pmdd is supposed to be dosed enough until you get iron reading of around.1 to.25 right?
2 T5 HO (54watt) and 3 T12 (40watt).
My params are this
Here is the tank so you get an idea of plant density. (lots of cabomba)
