I know there are a ton of threads on here already so I apologize in advance for the redundancy.
I am trying to raise phosphates in my tank. I started dosing nitrates a few weeks ago to get them above 0 and in the process I seem to have bottomed out my phosphates. I understand why this happened, and now I need to fix it. To make matters worse, I've been tinkering with the lighting recently because I thought the problems I was having was related to PAR, not nutrients, but that's a different story altogether.
I have been conservatively dosing Brightwell's NeoPhos (6mL/day, ~100 gal tank) for three days and the phosphate has not budged. I understand that the rock/sand is likely absorbing the phosphate which is why my readings are still undetectable with Hanna ULR Phosphorus, in as little as 60 mins after dosing.
My question is this - how quickly can I re dose without causing the opposite problem (and the algae that will surely ensue if I dose too much, too quickly). The bottle says 24 hours, but considering how quickly the rocks are sucking up the phosphate, I could be here a while... If the readings are still 0 after an hour, is it safe to add another dose?
