Hi,
I have a 150 gallon display tank that’s been setup for 20 months. Fairly heavily stocked. I have had ups and downs. I just cannot get the PO4 or nitrate down.
I have a man oversized skimmer. I used Chaeto prior then stopped and used GFO and now back to Chaeto. It grows well.
I feed 2-3 times a day.
PO4 is .5!!!
Nitrate 50
I cannot figure this out. I’m old school and shouldn’t have to carbon dose to get the levels down. When I ran GFO PO4 was still .2-.3.
any advice here? Need to get my levels down again so I can get some SPS back in the tank.
Thanks
