Nitrates mainly for me...although P04 was close behind. I think I got down my Nitrates to about 0-5 on the pellets and it crept back up to around 20+ after I had stopped for a while. A while being a several month period.
Keep in mind I dosed nothing once I stopped the pellets. My SPS were looking rough so I stopped just about anything other than the basics to try and stop the STN. As I stated above...it worked...even looked fantastic for a while...just slowly began browning out as things got high again.
This makes me think there must be a "sweet spot" that I blew by on the way down and then revisited briefly on the way back up.
Orrr...there was some other variable that I'm missing that may have had an effect. Its tough to say in this hobby. "Well...I changed my GFO out a month ago...is that why they look good now?? Hmm...I just did a w
ater change last week...is THAT why they look better now?? Hmm...the weather is colder now...is THAT why they are looking better now?? I just touched my arm, rubbed my face, and spun around two times...is THAT why they look better now??"
LOL.
