Low Nitrates / High-moderate Nitrates

[strykerdog11]

Hey guys I currently have a nutrient issue with my tank i’m having trouble solving. My nitrates slowly bottom out to 0 while my phosphates raise. This is forcing me to dose nitrates which I don't want to do if possible. Due to the imbalance I even got dinos which I have since resolved.

Current issues- most, all long term issues
-Low nitrates
-high Phosphate
-Bubble algae
-ph spike /fluctuation My PH spikes to almost 8.6 in the evening but drops to 8 at night.
- Had a Dino issue but resolved


Set up / numbers

Currently have a red sea max nano G2 all in one.
Running a skimmer and UV

Stock 2 clowns, watchman goby, yellow coris wrass. Had all these fish for about 4 years together now. (Since they have been together so long its hard to add anything else without fighting likely due to territorial space limitations )

Urchin, 2 emerald crabs couple snails Peterson cleaner shrimp

Auto Dose all for reef.
Alk ~9.1-9.6 range
Phosphate last test .07 ( sometimes get higher running gfo)
Nitrate last test 0.0

Coral ~ 12 heads of euphillia, 2 toadstool, 1 xenia rock, back glass gsp covered couple candy cane coral, gorge, tiny Kenya tree

Thanks! Im using hanna checkers, they are looking okay, slow growing but growing. Occasionally shrink a tiny but when nitrates are low, but once I dose they look great again. All aqua cultured, so pretty hardy.
