Cycling New Tank? (More like what is this slimy white/tan/grey stuff)

Did you seed your tank with mulm and black beard coated medium?

Test for Ammonia, Nitrates and Nitrides. If you are getting Nitrates, that means the cycle is nearing completion.
If you change or add any of the contributors of ammonia, you effectively detriment homeostasis and a new balance needs to be established. What makes this trickier is doing this in only a 2.5 gallon tank.

Its normal for mulm to break down if transplanted to a new tank so i wouldnt worry too much about that. Is there substrate in the tank or is this barebottom?

yeah, wasnt sure what BB was. also, try getting the bacteria from a tank that doesnt have any bad algae...

i would also get the tank water from the other tank (from the top and not the bottom) to accelerate bacteria establishment.

What's your params?

Where exactly is this stuff. if its on the plants, take it out and clean otherwise, trim or toss it. Use bleach as a last resort. I dont think you are there yet :)

Light and water circulation are other things to consider. is the light sufficient to sustain the plants, is the water stagnant?
i'm going to setup my betta tank tonight too so wish me luck.

This should be some help:

Wait for a week and check your parameters again. Your Nitrites should either begin to increase or decrease, depending on how far along you are in the cycle.

What brand & model number filter are you using for this 2.5G tank?

Also do you have any photos of this white/brown slime that's stuck on the plants?

Slime is usually pretty slow, so you should be able to get some good clear pictures.

I don't like that Hagen Mini E filter because the f-media is too small.

Looks like the white slime is taken over your sponge instead of the B-bacteria.

When you rinse it out, the white slime still dominates a majority of the sponge that why it grows back 1st.
  • Are the snails & guppy nibbling on the white stuff?
  • What are you feeding the guppy?
  • What are you using for the source of ammonia?

Do you happen to have any branches or driftwood or anything in there? I had this problem before where I am guessing the SAP did not dry out or something was coming out of my branches. I let my ottos and snails take care of it and they were at it for a few weeks before there weren't anymore.

Sounds like heterotrophic bacteria.

Monster Fish 10-09-2012 10:31 PM

The stuff in the filter looks like dead bacteria.

Yep. They produce ammonia so keep on monitoring that.

Monster Fish 10-09-2012 10:41 PM

Yup. Though according to the article, water changes won't do much. The best course of action is to be patient and wait for all of them to die off.

Monster Fish 10-09-2012 10:47 PM

I think to prevent any cross-contamination, go with a fresh batch of media. Also if you want to speed up your cycle, look for products containing Nitrospira bacteria only.

If you haven't already, raise the temp to 78 to accelerate the lifecycle.
