Can’t keep splatter hammers

[agamblinalot]

My other hammer and lps and even my montis are doing fine but I’ve tried two Aussie splatters and they die within weeks. My alk has fallen below 7 both times they die. I found my dosing lines were draining from siphon and have since corrected and got my alk back up to high 8s low 9s. I have a sinularia in the tank. Wondering if I need to rehome due to toxins.

Helloreef 15 gal. Nitrates 1.4, phos 0.0. Those just bottomed out the last two months cause of my AWC. I’m planning on feeding more.

Salinity stays between 1.025-1.026. I don’t test for anything else. Temp is INKBIRD with an eheim and kept 77-0-77-5. Not sure

Sounds like you have thought about potential causes for those failures to thrive. You didn't mention feeding lps corals. I have had best luck feeding them food they "steal" from the water column as it drifts by when I am feeding fishes. Your low P suggested that might be another cause for them not to thrive?

IMO, I would raise your parameters

I do try to keep my po4 at .05 and no3 at 5. I’m going to turn off my skimmer and see what happens.
