Thumbs down Did I kill them?

...the bacteria that is.

I bought a stand for my aquarium a few days ago and drained about 80% of the water, so that I could lift the tank, to get it onto the stand. I didn't vacuum the gravel, but I did disturb it a little bit, in order to rebury the air hose and some plants.

The problem is that, all of a sudden, my nitrite level is zero and ammonia is showing up again.

I would assume that the larger water change wouldn't affect the bacteria, but am I wrong?

The only other thing I can think of is that I may have overdosed with Prime when adding the new water. For some reason, I think I may have used 5mL of Prime instead of 1. I'm not sure, because I was just "doing another water change." However, if the larger water change couldn't cause it, then maybe I did overdose with Prime.

I know there are questions as to whether or not it does anything to nitrites, but it does say something similar to "in a nitrite emergency, a double dose may be used." Well, if I added 5mL, then that is a 5x dose.

Anyway, regardless of what I did to f* it up, am I basically just starting over again?

...or could I just be dreaming this all up and the reason the nitrites are zero is because my tank is cycling? Wouldn't the ammonia be zero too, at this point? The Nitrate level hasn't changed...

*sigh - I dunno....

If ammonia shows up in amount greater than .25 then change 25 percent of the water.
Eventually, the ammonia and nitrites will fall off and nitrAtes will appear assuming you stop overdosing with conditioner and upsetting the substrate ,filter,and possibly fish.
Keep feeding as discussed previously.

The most important medication in your fish medicine cabinet is.. Clean water.

Thumbs down Red/Brown Algae all over the place...

Hello again,

I'm still waiting for Nitrites to show up again. The ammonia seems to be staying at an acceptable level.

However, algae seems to be attempting to take over my tank. It started as brown spots in a few places, about a week ago. Now it is starting to cover the plants and substrate, and it is "blooming" in some places. I'm not sure if blooming is actually what it's doing, but what I mean is that rather than just being a film, it is now growing outward from the film. There are little "specks" of brown starting to pop up (attached to whatever the "film" is on...)

I hope that makes sense.

Anyway, I have read that Otos eat brown algae, but I don't know if I should add another fish to my tank, at this point.

So, what would you recommend that I do?

Brown spot algae is extremely common in newly set up system in which high ammonia levels are found. Once the tanks's done cycling the ammonia at 0 and the beneficial bacteria are establish this will subside.
Yes Otos will eat this BUT they're extremely sensitive fish when it comes to NO's and/ or ammonia - For that reason I'd not suggest to add any to your tank until after your ammonia's at 0 for good, otherwise chances the Otos would die on you are too big.

What are you testing the Ammonia & NO's with strip test or liquid?

I'm using the API test kit. I was to the point where ammonia was near zero and nitrites were starting to go up, but then I think I accidentally overdosed (5x) with Prime and killed the nitrites. So, now I'm back to just getting ammonia readings, which aren't even going up as fast as they were before. I don't know what you consider high ammonia levels, but I've been keeping it below .25 with water changes (which I haven't done for a couple of days now, because the ammonia has stayed below .25...

In my view, as long as you're using Prime with all water changes, and the ammonia is not rising above .25 between the weekly water change, OK.

OK, as in "OK to get an Oto" or "everything is OK the way it is"?

Sorry, didn't connect this to an oto. I meant that your tank is OK with respect to its cycling program if ammonia is not higher between pwc and you use Prime.

As for otos, no, I would wait until the tank is definitely cycled and then matured a bit, say 3 months, before adding fish as sensitive as otos. And then, only if there is algae they will eat present, either brown or common green. Brown algae (diatoms actually) usually only appear in new tanks during the first couple of months, and once the tank is stabilized it doesn't re-occur.

I do not hold the view that one should buy any particular fish to do a task like cleaning algae, unless you really like that fish and want it regardless, and algae is present to supply its needs. Every fish you add is going to impact on the bio-load, and that means one less other fish you can add. No point in filling a tank with fish you don't really want. If you follow that discourse.

Just give it time and keep up the w/c. I'm almost certain by the time your tank is "old enough" for a Oto, you're brown algae will have subsided anyway.
