I don't know these days what wrong in my tank?

I am seeing more green algae than my corollina algae and i add every night purple up and calcium also recently i purchased ro/di unit and i start mixing my water and i performed so far 2 time WC b/c of my nitrate problem. i still have 10ppm actually that is also weird according to my red sea test, it is 0ppm but api tested 10 ppm, i did 3 times a week still the same. so far i lost red leg hermits crab and xenia small piece. temperature 80-82, salinity 1,022-23 ppm.

 

i have all the test but iodine never tested ph 8,3-8,4 mag 1280 calcium 380 amonia 0 nitrite 0 dkh 8 phosphate 0 iodine ??? can guess among this numbers or because of purple up you think it might effect the iodine?

 

quit using purple up and raise your salinity to 1.026

 

can i just use calcium than? b/c i need that for sure if i want to put more coral in. by the way do i have to raise up to 1,026 and why so high? 1,024-5 should be fine b/c i also have hippo, clown and cb, my ich problem just finished, i scare about parasite that is why i keep it low.

 

ich can live in water around 1.020 and up. The reason I say 1.026 is that is the optimum level for growth. If your fish are healthy, and I mean healthy, not just swimming, your fish are going to be fine. I (and the majority of other reefers that I know) keep theirs a 1.026 because it mimics the red sea. For your calcium, I would say check levels and use a 2 part solution. If you don't want to mix your own brightwell makes a good one and 2 little fishes also makes a pretty good one. The purple up contains iodine which your salt mix also contains and in too high of quantity can be toxic to fish. I've seen this several times with high iodine levels.

 

is there test for that iodine? i will raise it tonight up to 1,026.

 

here is my RSM i can send more pictures if you want to b/c recently found out that i have compress zip software in my mac.
