That's right you don't understand I agree with that from your post. We are talking development with a manufacturer it's not something that has been finalised just a few ideas he will try. Sorry if you don't understand that and I can't make you.I thought we are here to share experience and ideas, i don't understand what is so top secret u can't share. And about YouTube video don't think it's necessary, water goes in from the bottom out from the top, lights and that's about it.
