I'm asking these questions here, as the tank will planted & I'd like to keep all my questions for this tank, together in the one thread.

The tank's been ordered, the light fitting is here & 2 x Eheim 2080's. They're currently cycling on my other tanks. They've been running since 2nd April.

I haven't been given a date for my tank to be delivered yet.

But say by 3 May, if new tank is here - will that be too soon to transfer the discus into a tank with those filters, or do I need to leave the filters where they are & running for longer before they're discus safe?

Also, will I have to transfer the stock over slowly, like I would for a tank that cycled from scratch. I'm hoping that by running the new filters on fully stocked tanks, it will be safe to transfer everyone across at the one time.

I don't want to move the discus unless it's safe to, so hoping for some advice. Thanks in advance.
