Dang I thought I had my guy. I guess no better way to learn than using it.Thank you. That actually means a lot. Every now and then, I'll get the urge to engage in meaningful conversation. Hehe
When it comes to the concentrated brine idea, I think there's some promising uses for the application. Although, I think it's still in its infancy and has a lot to be discovered, I think peristaltic pumps make it viable to explore.
I was so scared that my salinity would creep one direction or the other. But I've been doing this for over a year now and it's no different than what the skimmer does to salinity (throwing out a cup of skimmate each week to have it displaced with rodi). Not to mention, the jury is still out about the unknowns about what other trace elements are being precipitated from the concentrated salt mix and how that effects a reef long term.
As far as the arduino, I'm not a coder, I struggle with comprehension. my advice and what I did, is to befriend someone that knows a lot about software and coding, then be at their mercy. But his advice would be to get a starter kit and start with the blinking led tutorial and go from there. Haha
And perhaps @shoedy will bring his talents to this hobby.
