All seemed ok until about 3 weeks ago when I started getting the brown slime on the sand.
PO4 had been between 0.08 - 0.03 for a good few weeks and NO3 sat at 10
I tested a few days after seeing the cyano and my PO4 was at 0.08 but NO3 was 5 so I'm thinking maybe the cyano was caused by the nutrient imbalance.
A week on from those tests and my PO4 is reading 0 and NO3 is at 2.5
I can only think of a 25% water change as being the only significant change in the tank as it was the first WC I'd done in weeks.
My PO4 just after the WC was 0.11 so I dosed a very small amount of lanthanum chloride over the course of 2 days then tested on day 3. PO4 back down to 0.05
As well as upping my bacto balance dosing, I halved my heavy feeding regime in my tank to try and bring down the PO4 so that the nutrient ratio was more in line.
Now that I've hit rock bottom, I switched off my skimmer and fed my fish a bit more tonight.
Any recommendations for getting my PO4 and NO3 back up?
