Having trouble posting for some reason so hopefull this one will go through. I was curious about your water change plans, what are you planning on doing with the water you pull out? Have you ever thought of setting up a collection tank and using it for greywater? Really been considering setting up a big tank and thought it would be awesome if I could setup a big tank to collect the water I pull out from changes to use for the yard and garden and maybe even toilets. Wouldn't have to be a huge tank, just set it up with a bypass for once its full but would be more environmentally friendly that way and help recoup some of the water costs. AMAZING job so far, super jealous and hope all of the leak issues get worked out without too many more headaches, just keep remembering how fantastic this will be when its done. KUDOS to you good sir!!!
