Just thought I would update. I stopped dosing prime and relied on waterchanges and added bacteria daily. Ammonia did get high (1) one day but tank finally appears to have cycled. Ammonia and nitrite 0 and nitrate 5-10. I am now doing e/o 8g waterchanges. I really don't know why took so long. Now that I know (I sincerely hope!!!) that the tank is cycled I will use prime only if badge goes above yellow.
Good to hear you’re back on track. My New Years is not so happy this year, lost my cardinal and my flame in the last 36 hours. Essentially my tank went back to a full blown cycle, and no amount of water changed (min of 50% sometimes as high as 70%) would keep things at bay. Prime “appeared” to do its job but clearly not enough. I’m guessing the changeover from my 20L to 29 somehow nuked my bacteria (although I used all the same filter media, equipment, etc) AND added two additional bottles of bacteria.
It took adding some sand from my DT (as suggested) and a full large bottle of Bio Spira to get things rolling again. I’m currently at 0 ammonia with high nitrites. I’ve decided to keep dosing prime until the nitrites begin to fall because I’ve read that they are not as toxic to marine fish as opposed to fresh and if I keep changing out mass amounts of water, I’m just delaying things further.
Interesting throughout ALL of this, my Seachem badge never got above “alert” or .02 ppm Ammonia, so in future rounds of QT I will be acquiring a test kit capable of measuring free and total ammonia, even if skewed from meds at least it’ll give me a better idea and also dosing some ammonium chloride pre-fish to be sure whatever I “seeded” is actually working. I’m no longer going to rely on time frame in the sump for any seeded media only to find out when it’s too late it wasn’t enough.
This has been a QT session from hell and I’ve done countless others, some that were far more “lax” than this and with way more fish. I’ve never lost a fish to ammonia swings in QT it’s always been something else parasitic.
You win some...you lose some.
