As the title states, should one with low nutrients also have low alk or vice versa? I'm kind of at a loss right now with my tank. Tank was setup in July 2017, my system has been running stable parameter wise except for nutrients. Below are my parameters:
alk: 7.5
ca: 420
mg: 1350
no3: 25
po4: .16
ATI Hybrid 8x54w +LEDS (400-500 par on the corals, 300 on the sand bed)
I see the majority of my sps frags are either brown or pale. Some of them have decent color but some of them also have tips burning. I was always under the assumption that tips burning meant alk was too high. My parameters have been very stable for several months and the acros in the tank now have been in there for a couple months. CA/ALK are supplemented by a dastaco carx. Nutrients are controlled via arid reactor and zeovit reactor. I am only running the basic zeovit products to try and reduce nutrients. So far, these two reactors have only been able to bring down the nutrients to their current values.
I have a high fish bioload, 40-50 fish in a 360 gallon tank. 9 of them being tangs med-large and the rest are wrasse, angels and misc fish. I feed frozens once a day and pellets on auto feeder. Nori every other day and this is me reducing feedings to lower nutrients. At their highest, it was no3 100 and po4 .31.
What would cause the tips of some acros to burn but not others? Why are some acros colorful while the majority are not? At first I thought maybe too much light because my frag rack gets about 300 par and the acros on there looks to be doing well. However, a lot of people tell me they're running close to 500+ par and their acros grow and color great. Someone else brought up alk to my attention being too low compared to my nutrients. I'm wondering if I should raise my alk up to 8, 8.5 or even 9 since my tank is no where low in nutrients.
Any help would be greatly appreciated it. In the last couple months I've lost several high end torches, frog spawns and an elegance coral which I attributed to the high nutrients. Even now with the lowered nutrients, I am still seeing polyp bailout on one of my frog spawns. All the other lps I lost also exhibited polyp bail out. Needless to say, my wife was really sad..
