Red Bugs?!

[wojo]

hi guys, i noticed some of my SPS are bleaching out so i checked my params and the only thing i noticed was my Ca was little low (!340) but everything else is great.

so i started looking for the next thing in line which is the all famous red bugs. i am seeing red little bugs on the bottom of the glass, close to the sand bed. very tiny and they are all red. i always thought they are yellow with a red dot but i might be wrong or this is someting else.

i also took a closer look at the SPSs but was unable to see any of them on their surfaces, do i need to take them out to see them or should be able to see it from the outside.

please let me know what i should do next, im already seeing my red monty bleaching and some other blue stags also loosing color. i read there is a pill used for dogs i should dose but i want to be sure that this is what i am dealing with before i do.

any help is greatly appreciated.

Cheers!
