I'm dealing with a nutrient deficiency in my tank and have resorted to daily dosing 2ppm worth of nitrate (with potassium nitrate) and dosing 0.2ppm worth of phosphate (with potassium phosphate), daily. It's 500L of water volume and I'm adding 2g of kno3 and 0.2g of kpho3. I'm adding them dry to the sump, like how I used to dose my high tech planted tanks.
When I add it in the tank it's completely consumed 24 hours later (hanna checkers) so I'd like to up the amount I dose until I no longer see it hitting the zero point 24 hours later. However, I am worried about the nitrate bouncing up and down due to adding it and it getting removed, and what the spikes upwards in nitrate can do to fauna within the tank. Is that something to be concerned about? Or is dumping 5ppm nitrate and 0.5ppm phosphate in my tank each night ok for the inverts and corals?
