Ready to swap substrate -> now what?
I've decided to upgrade my substrate (3/4 pea gravel, 1/4 flourite, laterite mix) to Eco Complete. Should I keep any of the existing substrate in there? I've ordered enough Eco so that I don't need to add the old substrate back to achieve the desired depth. Assuming I can just take out all the old substrate , is it ok to give the tank a good scrubbing?
Any tips from anyone on how the substrate should be placed in the tank? As in, should it just be flat or do you slope it towards the front?
Thanks for any advice,
