Filter Fix and Oto Out...
So yesterday I found my tank was missing about 1g of water.. it has a lid so no cat could get at it.. found that my dog (who has developed an unfortunately fear of thunder which has progressed into a fear of rainy days thanks to stupid brat nieces screaming at thunder booms a few years ago when they visited...) had been under the desk (where canisters are) and apparently pushed up against them and messed up the threading of the outflow of the eheim to my tank (where it screws into the bottom).
Had to turn off and unhook the filer, confirmed it was the leak source at the sink and removed all media, put into tank water in bins and spent a good half hour ripping the house apart looking for tephlon tape with my husband.. couldn't find any so had o go grab some from a hardware store. When i got home I remembered to throw prime into the tank to bind any possible ammonia build up during the "off time". Taped the threadings of the outflow, gave it a new "o" ring and screwed it back together (with help of hubby). After passing a quick water test aka no leaks put media back in and hooked it back up. BY now the tank was about 4-5g full instead of 7 (from taking water to keep media wet). And of course turning the filer back on I got the obligatory mess of loose mulm and such shooting out.. so got to do a water change. Unfortunate the inline heater temp rose a bit from being in stagnate water (and then heating only about 1/2 the regular water volume) and got up to about 82F (usually barely 80). It went back down after the water change/top off (which I had to wait 1-2 hours to do to heat the bucket water with another heater to avoid dropping temp and stressing anyone).
Well unfortunately my oto Auto just passed about a half hour ago.. I have no idea why exactly.. I tested ammonia, nitrite, and nitrate and all were in perfect parameters (0,0,10) done right after Auto passed. I'm assuming it died from 1 of 3 things:
Temp raise yesterday, though gradual and only 2 degrees.
Ammonia buildup during the first hour the filter was offline, though it would not be much.. I'd expect the plants could have handled it.
Those nasty air pockets (what are they called again?) escaping sand when siphoning, but I have MTS in there to till the sand and prevent that..
Soo nothing conclusive but now poor Xerxes is alone (except for all the MTS in the sand and itty-bitty ramshorns). I dosed Melafix and will for 3 or 7 days just in case it was a disease of some sort.. though Auto never showed any signs of sickness (no discoloring, had a decently filed belly (he was never fat), nothing abnormal sticking out of him, no weird behavior except the minute before he died).. Hoping it was nothing nasty that will take out my betta boy.. Will try adding 2 new otos to the tank after they finish quarantine (have 8 in right now) in about a week.
