I tested for everything I had a test for last week, thursday-ish. They are as follows;
Salinity 1.025 which is where we keep it.
Ca 300
Cl 0
Ammonia 0
Nitrite 0
Nitrate 10
pH 8.5
kH 8
Cu 0
Po 0.25
The only inhabitants are 3 peppermint shrimp, a harlequin shrimp, an acropora (sp?) THAT happened to be on a rock as well as a mushroom that popped out of the rock and a coco worm along with a bunch of snails. I haven't fed the tank at all since it was set up, as was instructed by my friend. Last week I started feeding a tiny but, targeted to the corals and coco worm. Today my coco worm doesn't seem as happy. She doesn't come out all the way and when she does she is kinda curled up some. I don't run any white lights, just blue at about 75% as I was instructed, for 8 hour increments. However I have two skylights on that side of the house too (my suspicion of where the light is coming from). I have two powerheads on either side of the tank, one points to the other end and one points toward mid back plus the filtration. Since I added the second powerhead the coco worm has looked sad. Everything has movement, even the string algae on the sand.
Of course I don't have a lick of knowledge about any of this or what it does... I am so lost and so confused. It's literally a different language and there is sooo much info and sooo many ways to do this, it's overwhelming and frustrating and it makes me want to quit now before it gets to a point its more trouble to break it down and get rid of it.
I appreciate your suggested method with the triangle, but none of that makes any sense to me because I don't know what it means.
