Hi UKAPS,
New member starting out here with a question.
I have a cycled tank 60L Fluval Flex but want to swap out my sons multi coloured gravel for proper substrate
We have basic plants and a shoal of tetras with some snails, levels are all good
I plan to put in some volcanic base/sand/dennerle substrate, and top it off with black fine gravel
I will keep a cup full of the existing substrate and reintroduce this to keep the bacteria going
Do i have to wait for a full cycle again?
Can i maybe save 60-70% of the existing water and put that back in?
Do need to add in anything else please
thanks
