Also would you mind running down the entire stock of that tank?
Red tail sharks need a minimum of 55 gals and as they mature become territorial and aggresive towards eachother and can typically only be kept 1 per tank...so they actually weren't going to work out in the end anyway.
If there's other fish in there that aren't suited to the tank, if we can establish that now, maybe you can take some back to the fish store. The less fish you have in there producing waste the quicker you'll be able to get your tank parameters under control. They are pretty darn bad at the moment (the nitrite is alarmingly high) so daily water changes are going to be needed for a while.
So glad you got that kit right away!!!
