All my torches and hammers have been swollen for the last few months. Attached is a example photo.
Alk 9, nitrate 10, phos .05. salt 35 ppt. They are all about 2 years old, and only recently have gotten swollen. This hammer is the worst of the bunch.
Any ideas what can cause this?
No flow or lighting changes in years.
