I am having my LFS test my water for my new 10 gallon tank. They have tested 3 times so far (every couple of weeks or so). This time the employee found phosphates at a level 1. The problem is, the tank has no fish or critters in it yet. Just rock and sand and whatever is growing on the rocks. I do not feed anything to the tank at all.
Ammonia is 0, nitrite is 0, nitrate is just a trace, yet phosphates are at 1. SG 1.025. Calcium 450. Kh 7 and dosing reef fusion 2 every other day. pH around 8.1.
I use RO water from the grocery store. I had it tested the first time I used it and it was okay (not great) at 22 TDS. I use instant ocean salt. The mixed water had been sitting in a covered bucket for several days before I used it. I had done a 10% water change the day before this test.
Any ideas of where the phosphates came from? It does not make sense.
Next time I go back I am going to have them test the source water, the water in the bucket and the tank water to see where the phosphates show up. I am coming from the freshwater world and don't want to spend $50 on a black clown until I clear up this issue.
