Help! New tank

Its a Rena 75 Gallong Xp2 Canister filter I believe... Theres ammo-carb in the top portion and then I believe the bottom is mechanical filtration..? Its 4 pads from coarse to fine.
 
Welcome Dhillon14! We are glad to have you. It sounds to me like you are already on your way to becoming an addict;)
 
lol well I've been reading these forums alot these past two days and it's great stuff. Anybody have any other suggestions for media instead of the ammo-carb as I heard another type of media may be better to detect ammonia spikes. Also one of the yellow labs was hovering at the top of the tank all day long, Would move here and there but not really. After light outs the fish group together when I believe the sleep but this yellow lab was on the opposite corner of the tank all alone.. Is something up?
 
Help

I get home from practice today, run a few tests and these are my parameters:

Ammonia - 0
Nitrites - 0
Nitrates - 50

PH - 7. 6
Temp 77 Degrees

I've been doing daily water changes of about 20-30% how do I get these **** Nitrates down. Also the yellow lab has some damage on its tail. Is it fin rot? Pictures below, thanks!

First of all, I am unsure of what it afflicting that lab. It could be fin rot, or it could just be the result of a battle with one of the other fish. Of course, it could also be both, since fin rot is often a secondary issue after battle wounds were suffered. Fortunately, they have cheap medications that will solve the issue (Maracyn). As always be careful with using meds to treat one fish when there are other fish in the tank. The best bet is to move the lab to another quarantine tank, treat that tank with the meds, let the lab heal a bit, then bring him back. If that isn't an option, make sure that you follow the directions and don't overdose, and be careful!

As for filter media, I believe ammocarb is kind of a dual-edged sword. It will absorb quite a bit of ammonia, but it will also prevent the tank from cycling (growing the good bacteria) which means it is a risky proposition. I am not an expert on it, but it might not be a good idea to take it out, and I know some types release their ammonia when you add salt, so don't do that! Hopefully someone else knows a little more than me and can help you out.

Good luck!
 
The best way to heal fins is by clean water. They should heal up on their own without the use of medications and the cleaner the water the less chance the fins will get a secondary infection.

As for the nitrates have you checked your tap level? If there are nitrates present you may be fighting an uphill battle...
