Top soil acidic?

[2ofEverything]

I'm going to go to a great "pet shop" near me tomorrow to pickup a few things for the build and was wondering if I should get any substrate since this specific store is rather far away. I have 100% fertilizer free top soil and was going to use that as a substrate but understand that it might not be a good choice for the frogs. Would blending it with coco fibre be alright? I was going to use and abg mix but I'm really lazy and can't find tree fern fibre anywhere. I topsoil mixed with orchid bark and coco fibre alright? Thanks.

Hi,
I'm sorry this went unanswered.
Make the ABG and leave the tree fern fiber out.
Add chunk-coco husk instead.

IMO- You do not want to use the " 100% fertilizer free top soil "

Please feel free to PM anytime.
