Haha, oh I know about the water changes. I was just being ridiculous because I can be. Saving lives, even if it's a snails life, means more than being able to say no water changes for X amount of time.Well, sad to report that all butterflies have perished from the bacterial infections in the mouths. I used furan2 from day 1, added metroplex and kanaplex by day 3 to attack it with three different types of antiobiotics... in the end, they all succumbed. I even invited Maracyn2 late to the party to try another type of antibiotic but to no avail. Not really sure what to do from this point other than just wait until I've seen one sitting in a LFS long enough to assume that it incurred no mouth damage from shipping before I try again.
Otherwise, my other two fish in QT are doing just dandy and should be able to go into the main DT sometime after July 9th when my 76-day fallow period ends.
For my Ca levels dropping, it is directly related to me adjusting my CaRX to match my uptake in the tank as it ramped up. I had to do about 3-4 manual adjustments of the alk level by hand-dosing 2-part but I didn't do the Ca with it, hence the alk holding steady but the Ca dropped.
For Mg, I switched two Reborn CaRX media about 2 years ago and the media just contains a lot less Mg than the old Caribsea ARM media I used prior. So my Mg level decreases monthly with uptake and I hand dosed it up. I bought NeoMag media to add to the CaRX so it can help supplement Mg as it melts in the reactor but I haven't put it in yet. I hand dosed the other day and screwed up on my calculation and accidentally dosed it to 1800 ppm. So, thats why I did the 120 gallon water change to lower that number so all my snails wouldn't die.
