first off what you posted are not proper readings we don't know what your true parameters are by drops so it's hard to tell what the issue is , ph and ammonia are the only 2 I see with true readings , if your phosphate reading is true you have phosphates
how do I know this.. the correct reading will almost always read .03 ppm not 0 if its reading 0 both your nitrates and phos are high , your corals are telling you just that , you should not have any ammonia at all , how often do you do water changes how often and how much , do you do any type of dosing and do you test for these , do you use ro/di water , what test kit you use , how much do you feed and how often , whats your lighting , do you have any algae in your tank as this can hide both nitrates and phosphates and your test kit will not detect them ,
if you learn how to read your coral they will always give a early warning of arising issues ,
my temp is at 79 F at all times and lights are on a timer for 7 hours . My reef tank seems to be ticked some of my coral are angry at me like my leather toadstools and elegance . Every thing parameter wise is fine I even tested for chlorine lol . I do use ro water and my fish are perfectly fine . I have a 150 gallon. I know my ammonia is at .25 is that what would really be all the fuss ?
