New to Can Reef and SW

[Coralgurl]

Well, right now I love this hobby, I've taken over the tank...lol so here goes...
55 gl, 59 lbs rock-started with 20 lbs lr, added 10.5 and 29.5 dry rock 2 weeks ago,
skimmer, tunzal filter (no sump yet), vortech mp 10 and 40, koralia 750.

Livestock-1 of each bangaii cardinal, purple dotty back,blue green chromis and yellow tang(yes I know about the tang got him for algae), had a false percent clown but he jumped on sept long weekend.

Have a lrg frogspawn, green bubble, button, fox and pink goniopora coral. I liked the goniopora but read about it after so I'm worried, but so far is doing well.

Tank parameters are salinity 1.026. Ph 8.3, calcium 460, kh 8, phosphate 0.25, nitrate 0.
Lights - 2 t5s and LEDs.
I think the phosphates are up due to live rock, coraline algae is showing up, dry rock is flourescent yellow green right now.

Oh nd great clean up crew and unknown red crab, not sure what it is, no one has been able to I'd yet.
I will post pics later.
Thoughts?
Thanks
