Right now I'm still mixing my aqua vitro with my oceanic until I'm out of oceanic. It's been about 1/2 and 1/2
I have a 12 gallon nano that I have now changed 4 gallons in. So far one of my blue mushrooms looked like it was expelling zooanthelle, but that has now stopped, it's a bit shriveled and still blue so IDK. I've had problems with the blue shrooms in this tank suddenly bleaching and dying leaving just 1 or 2 that will reproduce and spread and then it happens all over. So who knows.
I have a green finger leather/kenya/colt coral in the tank that has been small and not really changed for a long time, this morning I looked at it and it looks like it has doubled in size overnight. Otherwise no other real change.
I have a 37 gallon seahorse tank that has had a total of of 14 gallons changed. I do large changes on this tank due to the messy horses. Most of my cyano I fight with is gone and a lot of algae is gone. May or may not be coincidental. I have a xenia and a kenya tree in this tank and they are doing well, but haven't noticed any other changes.
I have a 24 gallon nano that has had 8 gallons changed. this tank is an absolute mess right now after a heater malfunction and a crazy pistol shrimp, other than 1 colony of zoa's everything has died in the tank and even they look sick. Haven't noticed any changed in that tank, but I"m hopeful LOL
