Hi! I have a 7 months old tank that is starting to grow some coralline algae on the sump n a bit on the display. But the whole tank is covered in algae. Most of my corals are fine and growing well, except the algae keeps some from growing like my zoas. I used the PO4, NO3 salifert tester and both result are giving me clear water indicating nothing. Also for Ca, I have no clue how to do it. Looking at my sps and they are growing im thinking they are okay.
- salinity = 1.026 ppm
- kH = 10.3
- Ca = ???
- Mg = 1500
I dont have any inverts, only 4 hermits and 1 emerald crabs. I use an oversized skimmer and I grow chaeto farm. What should I do?
