So, tank is just about a year old and has been running great until last week. Happy birthday. Any ideas on what could effect one side of my tank and not the other? Right side had die off of all sps. Bali green slimer, teal birdsnest and one lps/torch. Zoas, ricordea and candy cane all ok. Left side no issues. Had same population on both sides, all clones from same parent colony.
Water is obviously the same throughout the tank, levels all fine before and after a 30% change.
Equipment is mirrored on both sides as well. Each has a koralia wavemaker and ai vega color.
Last change I made was to add control to my dc9000 return pump with a digital aquatics dci pump controller. Went from constant 50%power to 60-80% range daytime with 40% reduction in flow at night.
Trying to prevent the die off spreading. Any ideas?
