Re: Rescape 2 ft tank
Lovely tank. Nice foreground!
If you substrate is only a year old, even if there is base fertilizer, it should be fine. If you are using aquasoil type of substrate, you'll probably need to check how compacted they have become. Topping up new substrate if the current level is compacted would be a good idea.
Algae can get into your tank in many ways, not just from old substrate. Your plants, your livestocks too can be a risk. So I wouldn't worry too much about it.
If you want to keep your filter media and to have to do a complete restart, you can run that filter in the pail that you are keeping the livestock during the re-scaping exercise.

I have dwarf cichlids in my tanks! Do you?
