what could be causing burning tips
Most of my SPS is doing stellar, but I've got a couple of pieces that have shut down growth over the past couple of months, and I noticed today that a couple of them have what appears to be burnt tips.
Parameters:
Calcium - between 390-400ppm
alk - 8.3
mag - 1400
No idea oh phosphate and nitrate. I run pellets and GFO, and the tests always come out 0.
I dealt with a bout of cyano a while back and dosed with chemo-clean, after that I got SUPER aggressive with GFO changes and started dosing MB7. The bacterial production in my BP reactor basically fried it (as detailed in another thread so I won't rehash it here), and I've now got the modified reactor chugging away, but there was a window of about a week where there were no biopellets, and it's efficiency was all over the place from December until a couple of weeks ago.
would fluctuating nutrient levels cause burnt tips on some species? Or assuming my nutrients have just been driven way down low again with the reactor finally working properly, would an alk of 8.3 be high enough to cause tip burning?
