water parameters: perfect ammonia, nitrate, but high nitrite.

  • We are currently upgrading MFK. thanks! -neo
Ok everything living was moved to a sterile 20 gallon tank with a UV filter and treated with maracyn and maracyn 2. over the weekend my female rainbow passed but I don't know if that was from stress as the 3 males systematically wanted to spawn despite all the crap going on. At any rate the 30 gallon has been purged with scalding hot water and the substrate replaced with virgin silica sand. I'm going to move the plants and invertebrates over tonight. And leave the fish in QT a bit longer to see if anything goofy happens. I figure its another week till cycle will kick in on that tank then I'll have to bump em.

This just really sucks. Lesson learned, always have at least one week with test fish and always use a QT setup with meds ready. Funny thing is my ropes purchased at the same time in their own QT are doing great made it through their mandatory metro + dosing so as to purge them(they are wild caught and I've found internal parasites are prolific even in healthy specimens)

Gosh I just flushed over 100 dollars in fish this past month that sucks.

I'm trying to understand: You originally said that you set this tank up using "old seasoned gravel". To me, that means taking gravel directly from a live healthy tank, for the BB in it & adding to new tank.
NOT gravel from an old tank (even a healthy one) which was left sitting in a bucket for a long time. even worse if it was wet. That would already be stagnant and any debris, rotton. No "previous mystery disease" would even have to survive, for the gravel to pollute a new tank & kill fish.

Sorry, I'm tired & could've missed something. but didn't read anything about the gravel ever being heavily rinsed & dried out, or bleached rinsed, de-chlored etc between old & new tank?
All the best to ya!
 
He had older substrate off of a old tank that he just put in a bucket no water or lid if im correct for a month. Pretty sure thatd be a nitrate pool...

Could have been old carbon but he changed everything.

ya, & could grow a slew of new raging bacteria.. maybe our fish are lookin at us and thinkin "hey, YOU drink it first. if you're alive after 3 days, then try it on us."
LOL.
 
I've used stuff that sat for days, months, or longer before. I have used sponge filters that just sat in a bucket of water for several months dropped em into a tank plugged em in, add fish... no issue. As such I expected the gravel to not be an issue, but as sighted the percieved dead disease may well have been alive in the bottom of the tank. When placed in the bucket unchecked anything could have happened.

I said I should have used test fish on the tank to be sure its was good, I have plenty of garbage hybrid fry I could use. I also sighted the need for real QT as that would remove the initial confusion I had.
 
Yea but alot of waste is on ur gravel so who knows. Post pics of ur new setups!

Waiting for the light debacle with yalstore to get resolved on ebay so it has no lights just fake plants and some new fish in QT.
 
Gosh this tank seems set on spiking regularly. :^/ I have two huge filters that are seasoned on it trying to get it to chill. Its just the 3 rainbows, some shrimp and the snails at this point.
