It's room temperature. I've only tried the ESV stuff. It took a while to dial in the right dosage, but it has raised the nitrates on my tests so it seems to be doing its job. Five drops per day directly into the tank has keep the nitrates steady around 20 ppm for several months now. Does ammonium bicarbonate raise ammonium?When you dose the ESV nitrate, is the solution getting cold? That would likely indicate it is calcium nitrate since it's endothermic.
Have you tried ammonium bicarbonate yet?
Running activated carbon may help reduce risk of coral disease by lowering dissolved organic carbon. Increased DOC is linked with increased copiotrophic bacterial growth. If something starts dying, I take it out immediately for the same reason. Virulent bacteria won't stay on just that coral and may increase risk of coral disease elsewhere
It seems like you run higher amounts of light. Corals produce harmful byproducts during photosynthesis, ROS. Those need to leave the coral, so things like trace elements (mechanisms to move it out) and flow (making the boundary layer thinner) can help.
In a tank this small I recommend using sand too. My 10gallon is doing meh because I don’t have sand in it too
Ah ok so it isn't a powder. If it was a powder you mix into a solution, that would be the dead giveaway with it getting cold.It's room temperature. I've only tried the ESV stuff.
