A very general rule of thumb I use is keeping the nitrate to phosphate ratio around 100 to 1. So if your nitrates are 10, phos would be 0.1. Again, this is a VERY rough "guide" and personally if my nitrates are 25-30, I try to keep my phosphates anywhere from 0.1 to 0.5. As is almost always the case, stability is the key (once you have at least the minimum needed level of nutrients- in your case I would try not to go below nitrate of 10 and phosphate of 0.05)This is might be the sad reality
Thanks everyone, I will raise up my nitrates more and see what happens.
With Phosphates would it be bad to target .1-.3 or would that be considered too high? I would do it via Reef Roids and more feeding frequency.
Picture of the new to me blastos after a couple of weeks. The top one defleshed a couple of days ago.
Also, don't forget to manage your alk, salinity, temp, etc. Sometimes a tank will just have a "happy spot" where any given parameter might be outside a "norm" but remains stable... This is fine as long as you understand that you may need to acclimate any new additions to the higher/lower levels (and have anyone who receives coral from you do the same...)
Edited to correct: I originally wrote "A very general rule of thumb I use is keeping the nitrate to phosphate ratio around 10 to 1. This should be 100:1.
