After removing the HOB filter and skimmer, I dosed NeoNitro cautiously daily until levels came up to around 5-10ppm NO3. I also added Seachem Iodide according to the bottle instructions to bring up the level to a good value, although I have no Iodide test to verify. I also dosed NeoPhos but could never see any effect - the measured level is always between 0 and 0.03 ppm on the Salifert test.How did these changes work for you?
Early on in this, I was hit by a dino outbreak, which I treated with a UV unit.
The Kenya Tree and GSP started to perk up. I added a couple more fish.
After seeing consistent NO3 levels of 5-10ppm I added back the HOB filter and skimmer and have been running like that for the last few weeks. The UV unit is still on, but the dinos are almost completely gone. I wonder whether I should bump up the NO3 level to around 25ppm to encourage some competing algae.
