Hello KrisReef,
First of all I'm surprised and really happy to read so many "welcome" here, this is amazing
The tank has been up and running since January this year so it's still new. Like a lot of people with dinos issues, I let my NO3 & PO4 get too close to zero. The tank was fine, corals were good so I thought to myself 'hey, why test for NO3 & PO4 on a regular basis?' When dinos decided to show their ugly face, I tested NO3 & PO4 only to find I had zero of both... Now trying to bring levels up, experimenting with different things... This is part of the learning process I assume
