Topical Tropical Fish Forum :: View topic - Cycling. Talk amongst yourselves...discuss.

MelonHead

I saw a "discussion" (argument) on a nother board I thought I might start here Smile

For all of our experienced aquarists ou there...here's a scenario:

This should in my opinion be a really easy one. Let's say you've had a 90 gallon tank running fully stocked for a year with no problems. You then decide to upgrade to a new 125.

You're not keeping the 90 - you're replacing it with the 125. if you're using all the original water from the first tank, the substrate, and the filtration...the do you need to worry about cycling?

Then later I'll tell you what I read elsewhere...

Not when i am driving mate, sorry could not resist Twisted Evil

But in answer to your question, i personaly if i was transfering every thing over to the new tank, as long as the new water was treated first, then no i would not worry about cycling the tank as their would be no need to, due to the fact that you allready have a colony of benificial bacteria allready established in the fillter, you would just have to be sure that the filltration would be big enough to cope with the increase in water tur over, or add more filtration, which in turn would be seeded by the aged water, so avoiding any new tank syndrome, as every thing being put in would have been aged over a year. The new (extra) water you would put in would only be like a water change

Anyone else?

I don't want to just blurt out my opinion if the possibility of starting an argument between two others exists!!

If you could somehow lift the entire 90 gallon tank and set it into the 125 gallon and top off the water, your 125 gallon would be cycled. I don't see how moving or dumping the stuff from the 90 to the 125 would be any different, minus the minimal amount of bacteria stuck on the glass.

I would even go so far as to say you could throw out the top 95% of the original water before doing it and you wouldn't see any issues.

Looks like there won't be a fight here after all. Crying or Very sad

Exactly my point. I read somewhere else (I don't know where - from a Google search) where someone was arguing the point.

In fact, when I moved my Discus from my 55 to my 150...I used VERY little of the original water, old filters (plus a new one) and old substrate...and I NEVER had a spike. Granted, I moved the fish over a couple at a time...but still not even a spike.

Thought I might start a discussion, but it looks like we all know better here, huh?

I did this with my 135. Took the nastiest water out of my 50 and 29 gallon tank, swapped out one of the 2 bio-wheels and added fish. Never got a spike.

What is this, "Coffe Talk"??????? "A butterfly, it's neither a butter nor a fly..."

I've done something similar:

Just move the water, filter media, and blah, blah, blah from the smaller tank, add to the new, larger tank. No problems for me, and I have done this MANY times.

When I set up my 55 gallon tank, I just used the rocks and filter media the guy already had in it. I didn't use his water because I use all RO water in my tanks. No problems and no spikes, it worked just fine. The good bacteria mainly live in the filter media and substrate.
