Few topics I need some help on..Please.

[FinNipper]

I've been in this game for about 3 months now, and I've learned SO much from reading around in this forum. Thank you all!

1. My tank is 3 months old and I really haven't tested the water that much(I now know that's doing things the wrong way ). I had been medicating my tank for a bit(fungus clear, melafix, and quick cure), but now the medication is all gone, the water is crystal clear, but my nitrite level is crazy high(now that I've bought all the necessary tests). I'm pretty sure I've disturbed the biological filtration trying to save one guppy(which died ) in the main tank because I didn't have a hospital tank(which I do now). I think my plecostomous is breathing very rapidly because of my water condition. The ammonia is at about .25-.5 and my nitrates are at 10. A few hours ago, I added 20ml of bio-spira to my 20 [acronym:599fa17767="Gallon"]gal[/acronym:599fa17767] tank, will my nitrites go down to 0? I don't want my Pleco to die! The rest seem just fine, but I don't want to take any chances here. I've done several 15-25% water changes before adding the bio-spira to get rid of the high nitrite level, but that didn't work, so I'm relying on the bio-spira.

2. My african dwarf frog died a couple of days ago, didn't show any signs of stress, just sat at the bottom of the tank, no movement. Was it my water condition or the salt that I added to the tank? My [acronym:599fa17767="Local Fish Store"]lfs[/acronym:599fa17767] told me that salt can do a number on frogs. Do I even really need salt unless I'm using it for medication in my hospital tank? Thanks for any advice..

3. Most of my fish "sleep" about a centimeter from the top of the tank..quiet..is that normal? They're not gasping for air or anything, just wondering.

Depends on your set up. It can be a freshwater setup or saltwater

. Most of my fish "sleep" about a centimeter from the top of the tank..quiet..is that normal?

Perfectly normal...as long as its not gasping for air.

A few hours ago, I added 20ml of bio-spira to my 20 [acronym:de796b2d35="Gallon"]gal[/acronym:de796b2d35] tank, will my nitrites go down to 0?

i doubt it. Regular water changes will help. It might be the nitrite spiking...but i wonder why there is still ammonia

I think my plecostomous is breathing very rapidly because of my water condition

Yes its because of the water conditions. I think its getting nitrite poisioning

Hope i've helped

My tank is 3 months old

Thats a little odd. It should be cycled by now

[tkos]

I am confused. You say your nitrates are 10 but that you want nitrites to go down. Your nitrates are nothing to worry about. But any amount of nitrite or ammonia is unacceptable and you should do water changes to get them to 0. Do not worry about water changes affecting your bacteria as they are firmly in place on the rocks and filter media. Your tank is probably recycling because I assume you change your filter media regularly. Don't do this as you loose all the good bacteria eveytime. Just rinse it out in old tank water and put it back in.

A pleco is too much fish for your tank assuming he is a common pleco. He can get to be 24 inches long, and don't think he will just grow to the size of your tank like they say at the fish store.

Don't bother with salt. It can affect scaless critter like frogs in negative ways.

BioSpira is a great product but make sure you keep it refrigerated or it will be no good in a matter of a day.

I've heard salt is bad for plecos for this same reason.

[Allivymar]

okey dokey; couple of things:

Your tank is probably cycling again and I agree, its probably due to all those medications kiling your biological filter. Thats the number one thing you have to deal with. Bio-Spira may help, but you need to get that ammonia and nitrite out of the water NOW. Ammonia burns the gills, nitrite competes with oxygen; both suffocate your fish (most probably why your plec is beathing heavy; cause he can't breathe!). There are things which turn ammonia into a non-toxic form, like Amquel, but they don't do anything for nitrites. My suggestion is water change water change water change! To **** with your biological filter atm; get those toxins out of the water; I'd do a 50% change right now. Then retest your water and see what the levels are. You'll probably have to do more changes in the ensuing days; keep checking levels each day. If theres ammonia and/or nitrites? Water change.

The salt thing is controversal. I don't know about the frog, never having one, but I did research on the salt/catfish thing and can't find anything to back up the "salt is bad for cats" idea. I did find a number of scientific studies which used salt to treat nitrite poisoning in cats tho! Apparently the chloride competes with the nitrites in the gills. Personally, because of all the concern with cats n salt, I'd water change instead. But if anyone is interested in those studies, let me know; I have em bookmarked.

Lastly, as you are discovering, crystal clear water doesn't mean good water for fish. Those tests are your key to keeping the tank water a good place for fish to live; keep on using em!

Wait, I'm confused. FinNipper has a Penguin filter with a bio-wheel... I thought the bactera grew on the bio-wheel, meaning you can change the filter cartridge without affecting bacteria levels? Also, if you vacuum the gravel, doesn't that seriously affect bacteria?

Ryan

[TankGirl]

Gravel vacuuming should not impact the bacterial colony. The Biowheel helps a lot but if you kill your bacterial colony with meds it will not preven the tank from going through a mini-cycle.

[Allivymar]

The whole point behind the bio-wheel is to provide a large surface area for the nitrifying bacteria to inhabit. They don't JUST live there; they are on every surface in the tank, but since its such a large area and can hold so much bacteria, you can change filters, completely gravel vac, without canning your entire biological filter.

But, as TankGirl said, all the surface area in the world makes no diff if the bacteria aren't there. Quick cure has been known to kill off the nitrifying bacteria; Melafix won't and I don't know about the Fungus Clear.

On another note, now that I think about it, it may be the meds themselves that affected the plec. Most meds (except for antibiotics) are poison based, like ich meds. Those scaleless fish absorb WAY too much of the poisons and it it detrimental to their health. Quick Cure, if I'm correct, contains Malachite Green. At full doses it can kill the scaleless fish as well as parasites. How did you treat the fish FinNipper? Those water changes may be even more necessary then I previously mentioned, as you may need to get all the meds completely out of the water. A fresh carbon filter will help too.

[FinNipper]

I'm sure all of the meds are gone by now, because I've done many water changes and I did put in a new filter media a week ago. I only used a half dosage of quick cure because of the pleco and he wasn't breathing so heavily durring the medication. If I do water changes right now, will that get rid of the bio-spira, because it says not to use ammonia removing agents like aquaclear, which is what I use. All the other fish seem healthy and playing around, but yeah, I know not to take any chances. That bio-spira stuff is expensive and I thought it would deal with my nitrite problem. It hasn't been 24 hours yet since I used it, so I'll wait ti'll this evening, test the water, and if nothing has changed, I'll do a big water change. Thank you so much for all the help everyone, I'll keep you updated on the pleco and water quality.
