Well got my way with the misses and its bigger tank time :thumb:

Probably going to get a rio jewel 400, 5ft 400 litres (current is 90 litres). Have been told by my LFS to rip the standard internal filter out will run my current aqua one aquis 750 and buy a new bigger external and run the two. Have an air pump so will use that and my current rocks. Will buy more trocks and thinking of using normal tank sand not coral as its oushing my PH too high and struggling to bring it down. Anyway thinking of blacking the back of the tank so you cant see pipes etc and getting more rock so i can build some good hideaways for them. Then will run the tank for a week or so with the new filter and mostly set up then was thinking of transferring the old sand and rocks and then puttting the old tank water and fish in together.

Never done this type of upgrade before so sure you can give me pointers, am sooo excited and will then let it run for a month with current stock levels then add some females of the same species i have now

I would put the new filter on the old tank and let it run there for 2 weeks. That way when you put it on the new tank you shouldn't have much of a cycle.

There's no need in transfering the old water to the new tank as there isn't much good bactetia actually in the water (it's in the filter).

I'm confused about the sand. Do you have 2 tanks going now? One with sand and one with coral?

no my new tank comes friday so will set it up over the weekend. Good idea about running the new filter on the old tank at least i will have some goodness in there and a fully working old one (on the new tank).

Running the new filter on the old tank needs to happen for 2 weeks so that bacteria can colonize the new filter.

If you transfer your used filter (don't clean it) and the original fish at the same time, you should not have to worry about a cycle.

Wasn't clear whether you were transfering the used substrate or not.

Running the new tank for a week without fish and with a new filter is not helpful.

ok cheers, am getting new sand not coral (because of ph issues) and new coral stone but will also use my existign coral sand and stone because of the bacteria etc that has on it.
