Thanks for the advice. I would have loved that when I was cycling.

I had to leave my 55gal tank with several long time fish for a year and 1/2 only too come home and find a green tank with no live plants, 4 of my 15 fish left. My husband tried to replace the larger fish with smaller ones but my love for my aquarium isn't a love we share. He did the best he could and I am greatfull I had some of my old fish left to build my new family around.

My question is.... How do I know when I have to many fish in my tank? Like I said, I have a 55gal tank and at this time I have the following fish;

1 6yr old Blue Gourami; 1 6yr old Tiger Barb; 1 2yr old Kribensis (female); 1 6mo old Red Fin Shark; 1 6mo old Red Tiger Platy; 1 6mo old Pacosamus; 1 6mo old Giant Gourami; 2 6mo old Jewel Tetra; 2 6mo old Glass Tetra (red eyed); 2 8mo old Multicolored Cichlids; 4 6mo old Sailfin Mollies (2 blk, 2 wht); 2 6mo old Pineapple Swordtail Platies.

All together I have 19 fish in my tank and am wondering if I should remove some of them as I am learning more about the size each of them are going to grow in size.

Thank you for your input.

A well written explanation using "little words" for the beginner. I have read articles trying to explain this same topic, but were very confusing to understand.

how many times a month do you have to clean a tank?

I wish there was a way for this post and the post on proper stocking levels to be readily available for all of the people who only use the main blogs on FC, It's sad to see when folk have setups that you know are doomed to failure, you can try to help them out by providing proper info, but usually they think you're coming off like a know it all jerk. It's very apparent that they are really excited about their new pets, and I wish everybody would be able to enjoy the hobby as much as I do. I'd bet that for every one person that has a rewarding aquarium keeping experience, there is probably twenty who's experience results in a frustrating failure.

One of my big mistakes when starting to cycle my tank is:

I over cleaned my gravel. I didn't have any bacteria start to grow until I actually stopped weekly water changes and gravel vacuuming and let the tank sit for almost a month.

Maybe if the Pinned Topics came out and gave them a hard poke when they logged on...

We do need a post where people are bound to come by. They mostly skip the Pinned Topics section and if cycling is ever mentioned to them, here's easy access.

Awesome post. I hope folks who are just starting out read it instead of walking into this blind.

We have had a number of threads here on FC.com about "cycling" a new fish tank, and I thought I would post my current thinking, in the hope that you guys will chip in with your thoughts. Sorry it is such a long post -- but this stuff is really important.

Cycling a fish tank has nothing to do with a two wheeled vehicle; it also does not mean to simply let the tank run with water for a week or two. Cycling refers to getting the Nitrogen Cycle established in a tank. The Nitrogen Cycle is what makes it possible for us to keep fish in glass boxes which are, essentially, their own toilets. The Nitrogen Cycle starts with ammonia, which is the result of fish metabolism, dead plants, etc. and which is very harmful to fish; a certain set of bacteria convert the ammonia into nitrite. Nitrite is also pretty harmful to fish, and a second group of bacteria convert nitrite into nitrates. Nitrates are much less harmful to fish, and nitrates can be removed by having lots of live plants, or doing frequent regular water changes. There are also just coming into the hobby a number of products, both as additives and entire filtration systems, that will house the group of bacteria (which need a low oxygen environment = anoxic or anaerobic) that convert nitrates into harmless nitrogen gas. This last stage of the Nitrogen Cycle works very much the same way that live rock works in a Berlin style marine tank. The technology is coming to the tropical fish hobby/industry from the commercial aquaculture of food fish industry -- and it is now possible to complete the cycle without doing weekly or regular water changes.

The requirements for the Nitrogen Cycle to get going in a fish tank are 1) the bacteria -- they can be allowed to build from the population in any tank, or they can be "seeded" by adding gravel, plants or filter stuff from an established tank into the new tank, or from any of the liquids or powders available as tank starters at your lfs. 2) The bacteria need a place to live -- which is usually part of the filtration system of the tank, although the bacteria actually live on every surface of the aquarium. 3) They need food -- in terms of ammonia to start with, then the nitrite that is the product of converting the ammonia -- the food can be in the form of adding ammonia directly, or from the fish.

It is very important to understand that without all three components -- the bacteria themselves, places for them to live, and food for them -- the Nitrogen Cycle will never become correctly established in a tank. There are many ways to get the Cycle started in a new tank. One is fishless cycling which involves adding ammonia (or letting some cocktail shrimp decompose) to the tank in enough concentration and over time for the bacteria of the NC to get going. The problem with fishless cycling is that most folks do not want to look at an empty tank for 4 -- 6 weeks while they feed ammonia to the bugs, or watch a few shrimp decompose. You can also get the NC going by adding something to "seed" it from a healthy existing tank. This can be a sponge filter, plants, gravel or filter medium. In my experience what works best, especially for new hobbyists with their first tank, is to use Nitrogen Cycle starter products from the lfs. These can be in the form of liquids with millions of live bacteria, or dry powders with suspended bacteria and food to get them started.

I have tested all of the methods for starting the Nitrogen Cycle in a new tank, and in my experience what works best is to start the new tank with bacteria either in liquid or dry form (and to add any "seeds" you can get), and to slowly add fish to the tank over a 4 -- 6 week period. You should absolutely buy your own testers for testing "The Big Four" -- pH, ammonia, nitrite and nitrates. The test strips work just fine, and they are the best investment (other than a good book) that newbies can make in their aquarium hobby. LFS's like to encourage folks to bring in water for them to test, which is fine -- except that the Nitrogen Cycle and how it works is so critical to understand that it is really important that you do the testing yourself -- don't just rely on your lfs telling you that things are "ok". You need to have the numbers for "The Big Four", and to keep track of them in a log, as the direction/trend of any tank parameter is much more important than the absolute number -- unless the numbers are so high as to really threaten the health of the fish.

Bottom line, for me -- buy some test strips to test ammonia, nitrite, nitrates and pH -- add some "starters" either from the lfs or from existing healthy tanks -- add the fish over a 4 -- 6 week period -- test "The Big Four" each time before you add new fish, and keep a log -- don't rush things, and most important --- LEARN ABOUT FISHKEEPING AND HAVE FUN!
