Cycling...

  • We are currently upgrading MFK. thanks! -neo
beneficial bacteria builds up in your filter and on surfaces of tank so if you remove the water from the 55 and then fill the 90 and use your established filter plus adding prim to your tank its almost as if you have already cycled it al you really need in this case is to allow the filter to cycle the water in the new tank for about an hour or so but i would recommend using water from your previous set up too this way its almost as if all your doing is a water change because only about 15 to 30% of the water is new you could probably get away with up to 50% established water just add the new water gradually over an 8 to 24 houer time frame so as not to change the temp or chemistry in your tank to drastically for the fish
 
I would not use all the water from the 55 and the filter unless you are not going to leave it setup because it will go haywire on you.If you plan on keeping both tanks up and running I would use 1/2 the water from the 55 gl and its filter.A 100% water change and new filter is never good on the tank
 
I think you guys are confusing me with someone else in this thread...I am starting a new 55 gallon with all new water...I have never cycled a tank before....all I've ever done is ad the de-chlorinating chemicals to the new water and things are just fine

Yup. Someone hijacked your thread.

Why cant you just by the chemicals to add to the water when you initially fill the tank? This is what I have done for years with our 10 gallon tank and have never lost any fish...I guess I dont see why cycling is needed.
 
I emptied the 10 gallon about a month ago now, cleaned all the algae out, bleached all of the decorations, cleaned the gravel, etc while the fish were in a bucket of the old water with an aerator. I filled the tank with new water and added the chlor out chemicals as recommended and waited about 30 mins before adding the fish....didnt have any problems and things are fine in the tank...algae is under control and I didnt get any bacterial or algae bloom.
 
Fish release ammonia into the water… bacteria transforms ammonia into nitrite, then into nitrate… Cycling a tank means establishing these bacteria…
 
That is why cycling a tank is necessary…
 
Anyone who has kept a tank for any length of time cannot truthfully say “I have never cycled a tank”… As with or without our knowledge, in time bacteria will form in our tank.
 
By not cycling, or by thoroughly cleaning an established tank as you have suggested… You are putting your fish through a miserable process of elevated ammonia. This will commonly kill fish, but some may suffer through it…
 
It seems you are very lucky as your fish have suffered through it…
 
This is a mistake most of us have made at some point due to ignorance. Now you are not ignorance and it’s up to you if you choose to make your fish suffer through this process in the future…

So what should I do to adjust my 10 gallon to where I can transfer my cat into my new 55 gallon tank? I want to make sure that I dont lose him in the transfer.
 
It sounds to me like you need to Cycle the 55 gal... There are a lot of ways to "cycle" a tank...

You can simple do as many water changes as necessary to keep the detectable ammonia/nitrite to an absolute minimum until the bacteria has established itself in suitable quantities.

There are a number of "bacteria in a bottle" type additives. I've heard mixed reviews of most of them. "Dr Tims" and "Seachem Stability" tend to have better reviews than most others I've heard of...

"Fishless Cycling" is also an option. A very good one in my opinion. Taking the time to do a Fishless Cycle takes patience, but also gives us a chance to get a very practical lesson on establishing a tank. It's a great learning experience for newer hobbyists... Plus fishless cycling can prep a brand new tank with enough bacteria to handle the waste produced by a full stock of fish, where other approaches only build enough for the amount of fish used in the cycle.


Use the search engine here and/or your favorite search engine to read up on the term "cycle" There are a lot of approaches and a lot of ideas on "perfecting" the process.
 
Thanks...I will be doing a fishless cycle on my new 55 gallon but I want to make sure that the 10 gallon that I have my catfish in now is as close to the water quality as the 55 before I put him in there...follow me? I have never cycled a tank before....just de-chlorinated the water and added the fish...have never had any problems with dieoff. I have never tested the water in the 10 gallon to see whats going on. What do I need to do to get the water in the 10 gallon up to par?
 
Ya i plan on taking down my 55 right after i fill up the 90 so its all going in. thats what I was thinking tho I think it is going to be just like a normal water change... This is perfect I am pretty excited for my tank to get here!
