New corals

Hello there just to share and hope to get some feedback on my recent purchase, I got a combo frag for $40 at one of my lfs, and a frogspawn on another lfs for $20. The combo has some zoas, that they are 3 different species (colors) and a trumpet, frogspawn is brown with green tips in one side and purple in other half. The zoas on the right side are closing I have some strong flow directly to them it can be the cause , light I have a panorama pro 12k/453 19w in a 12g nanodx. Question should I dose anything?
Thanks

 

I don't know about dosing. Do you have a test kit for calcium? The corals look great as well.

 

if you do regular water changes weekly no, if not test your calcium and add as needed for the lps

 

Very nice adds, congrats. Test for alk, Ca and Mg. Keep your alk between 7 dKH and 11dKH, your Ca between 380ppm and 450ppm and your Mg between 1280ppm and 1400ppm.

 

Ok thanks , yes I'm doing weekly water changes, I just start getting sea water or catalina not sure, I was mixing my salt water with R/O, but always shows 0.25 of phosphate after mixing not in the tank. Now not sure if is my kit but this sea water shows same amount of phosphate.I have been fiercely fighting and algae problem for months, Got new LED lights, water changes, still I see an algae film on glass after few days of water change.
Thanks for input and comments
