Parameter Check - Low Cal and Alk

[Makaveli]

Hello Everyone!

I have my tank running for now about 7 months. I went through a phase of velvet that wiped the tank. I went fallow for 50 days. During the fallow period I did add corals. The tank is now up and running again with 2 clowns and corals. I was hoping I can get some insight into my parameters. Any comments/suggestions/criticism are welcome since I am not a softie, I am a SPS:

Tank: 35 Gallon Waterbox All in One
Using only RODI water
Ammonia: 0
Nitrites: 0
Nitrates: nearly 0
PH: 8.15 to 8.3
Mag: 1230 (kinda low?)
Calcium: 375 (kinda low?)
KH/Alk: 6.5-6.6 (low?)
Phos: 0 (too low?)
Salinity: 1.026
Temp: 80 celcius
Powerhead on one side: AI Nero 3
Powerhead on the other side: regular affordable powerhead
Plenty of surface tension and water flow
Protein skimmer yet - Aqua Maxx Bullet 2 HOB working well
In the back chambers, I am running filter floss, chemipure blue and Seachem Matrix.

Fish: 2 clowns

Inverts: minimal (4-5 nassarius snail snails which I can't find and 4-5 torch snails

Corals: Zoas, Torches, Hammers, one sps (birdnest)

Please let me know what you think. I am thinking of dosing all-for-reef but haven't started yet and thought I would post here first. Fish are happy and corals seem to be happy except the Anemone (rose bubble tip) that I added only a few days ago hasn't really opened fully and is chilling on the side.

Should I try to raise nitrates, calcium, alkalinity and phosphates? Should I do nothing and just do water changes every two weeks? Should I dose all for reef?

Any comments are appreciated.

Thanks!

I would do some water changes do bring up alk and calcium together

Then use all for reef to maintain the levels. And feed a little more to bump up nitrates
