So I've had my small 35L tank running for a year, and think it must be time to finally upgrade my tank! (Something I've been trying to fight off for a while...) Anyway, so I'm currently looking at getting an Aquaone 620, but I'm not too sure about the steps to upgrade.
My understanding so far is that if I have established media, I should be using them all in my new tank, so if I transfer everything over the bio-load should still be the same. If I do this, I should not need to cycle my new tank, right? Although I am also assuming that if I transfer the substrate (fluorite in this case) I might be hurting some of the bacteria colonies in there, so I am expecting a slight ammonia/nitr*te spike, and will just keep up with the water changes. But essentially, I should be able to move my fish over to the new tank instantly, right?
Unfortunately I don't really have the room in my house to have both tanks running concurrently, which is why I'd like the change to go as quickly and smoothly as possible. I'm intending to do the following:
1. Move all the fish to a new home (i.e., bucket)
2. Empty the water of the 35L tank to around 1/4
3. Move the substrate & plants, and attach filter
4. Move the old tank from its current perch, and move the new tank there
5. Fill new tank with a bit of the old water, and reintroduce fish (?)
6. Top off with new water
7. Fin!
Now as all my projects go they don't typically go according to plan, so I'm hoping you guys would be able to help with figuring what I should or should not do before hand. I'm not particularly sure if I should do #5 or #6 in any particular order, or if I should have standing water set aside to match the parameters of the old tank as closely as possible, in terms of ph, hardness and temperature. I guess I should be doing this anyway, but as I only have one or two 20 litre buckets that I can reliably move around, I don't know if I can add enough water that way.
Any help in auditing my moving steps would be appreciated!
Some other questions: I intend to add bronze cories into my tank as well, but hear that fluorite will ruin their barbels, so was thinking that I'd mix my fluorite with some other dark sand substrate - any recommendations? Should I also be worried about the sand compacting? I'm intending this to be a planted tank.
I was also thinking of adding a piece of driftwood into the tank - how do you guys prepare this? I heard that people boil driftwood but I don't really have a pot large enough for it... Would maintenance of this be as usual with other ornaments - taking it out of the tank and cleaning once every month?
Thanks everyone
