Very helpful, Byron. Many thanks.
I recommend making this a sticky thread--it answered several of my questions for which I've been googling.

I must be misunderstanding something...I thought that you needed a balance of all these types of bacteria (including anaerobic) to complete the nitrogen cycle. Can you explain further why one would want to limit the growth of anaerobic bacteria? Thanks.

This is correct, and what i do advocate in the article.

You don't want it to take over, as hydrogen sulphide can easily occur. The snails, not too deep a substrate, and live plants should keep this balanced.

Do you mean any snails or just Malaysian Livebearing snails cos I have some snails (it's hard to keep them with clown loaches) and they eat plants mainly - especially healthy ones.

All snails will assist in breaking down waste, but the Malaysian Livebearing snail is the best for burrowing through the substrate which is also important to prevent widespread compaction.

MLS do not eat live plants that are healthy; they will only eat decaying/dying matter. Pond snails and acute bladder snails are the same for this. Some of the larger snails may eat plants.

So is stirring your sand by hand to get rid of the gas bubbles a bad idea? Does this mean I need MTS?

taking a break from fish-keeping.
3 lovely male betta still keep me company.

I never do this. Some compaction is necessary as I point out in the article, it completes the nitrification cycle. One doesn't want the whole substrate to go though, and MLS are in my view the best way. In marine systems this can be done by worms, so i read anyway; but we in fresh have the much nicer snails.

Oh gosh. Well all this time I though all the bacteria was in the filter too. Does this mean getting a new filter has little impact on the cycle?
I'll have to pick up some MTS this weekend.

If the tank is well planted, you can change the filter, wash the media under the tap, or throw the filter away...and you will have no issues bacteria-wise. The plants take up a lot of ammonia/ammonium.

If you can't find MLS locally (they can be difficult to acquire) I can send you some on some plants, as you are in Canada, if you pay the postage.

Wow great post!

Ok now using this knowledge why don't you make a product that instantly cycles an aquarium or in less than 2 days anyway.

Would that even be possible?
