Thank you very much for that!
I had forgotten that you were a fellow cap'n style grower!
I'm having some issues at the moment and has been a lot harder getting answers about cap'n style sense the cap'n himself left.
I'm having some pond smell issues due to the fact that when i swap the res I can't remove the final litre or so from the bottom of the container and it's leaving me with bad smelling water.
I'm days away from brewing a tea, just waiting for myco soluble to arrive
You can use a wet dry Shop Vac to remove the remaining liquid when you are performing reservoir changes.
