So usually I don’t really need to worry about phosphates. But recently they got up to .1 I like to have them below .05. So no problem I added GFO they came down for a few days (.03) then went right back up. I repeated this cycle 3 times. It keeps going right up again - it’s currently at .08.
The only thing I did recently was replace my CalRx with a larger unit and when I did this I replaced my Media with Caribsea ARM (same as I was previously using) so I checked my effluent and it was outputting .12 Phos at 60ml a minute or almost 23 gal a day on approx 120 total gallons (minus rock) seems like the source to me?
I’ve never tested my effluent Phos before but this is the only thing I have found to be a possible source. Maybe I just got a bad batch of ARM?
Has anyone out these tested other types of media to check Phos output?
With all of this said my SPS seem happy as can be. So I’m not inclined to change anything at the same time I can’t stand using GFO.
