HOB Filter question

[swifty]

I have 2 AquaClear 50 filters on my 29g. I recently upgraded my 20g long to the 29g, and want to setup the 20g.

I have 2 possible ideas and questions on each.

- If I move one AC 50 to the 20, will my 29g be ok? Also, I'm guessing the 20g would be instantly cycled, corrrect?

- If I keep the 2 filters on the 29g as they are and buy a brand new AC for the 20g, could I just move the media from 1 of the 29g filters to the new filter, and the tank be instantly cycled?

They won't be instantly cycled but it will definitely help and you would be able to LIGHTLY stock the 20g right away with little to no worry either way you decide to go. What is the 29g currently stocked with?

I think an aqua clear 50 would be fine for the 20 and 29. The output/flow of aqua clears are strong. I have an ac 110 on my 55 and it works wonders. You'll be fine. But your tank wont be cycled right a way.

Do a 50% water change on the 29 and put the water in the 20, top off both tanks and add prime, put one of the AC 50 on the 20 and you should be good if lightly stocked. I would probably dose both tanks with seachem stability.

^This add water from the 29 to the 20 and pop on one of the filters. Fill the rest up with freshwater and add in decholrinator. You should be good to go to lightly stock.

It makes no sense to start off a new tank with dirty water from a running tank. There is very little beneficial bacteria floating in the water.

I agree. If adding nitrates is your thing then by all means, but you gain very little in the way of bio.

I move bio around from tank to tank all the time for an " instantly " cycled tank, but I stock lightly and go slowly with adding any stock when I do. I move filters around quite often as well.

if the stock being put in the new tank is from the old tank it wouldn't hurt to use some old water ,it is after all the enviroment the fish are used to..... .and it will help with temperature stability...I always use some old water to help with temp and stress issues... and yes the filter swap should work fine... maybe add a sponge filter to the 29

Good point, but what would be the purpose of putting old water in the other tank he's setting up? One tank is becoming 2 tanks. Sounds like the 29 is the upgrade and the 20 is a new setup. I could be wrong

Just trying to understand the logic of putting old water in the tank without stock.

I think if you want the tank be fully cycled, at least 90% of water in the tank from a fully cycled old tank. And your filter is fine, if you are not planing on keep some messy eaters.
If you want your new 29 gallon fully cycled instantly, I have an idea maybe work. pull all the 20 g into 29 g, and add 1g new water to 29 g everyday....
