Thought I would share my few latest projects. Built my first light rack for my 25g Lagoon and liked it so much I built one for our new 105g. Also was sick of carrying buckets, heaters and pumps so I set up a mixing station in the garage.
Really nice work. One quick question regarding the hose spigot on the mixing station. Is that a brass fitting or is it a gold colored PVC? If it's the latter, you may want to consider replacing that. They sell a thread to hose adapter at the big box stores. You'd want/need to add another valve just before it. If it is in fact a gold colored PVC, then ignore my rambling.
Thanks it was fun designing and building it. Those are plastic fittings I am going to change the one off the RODI barrel to a valve just to speed up the flow. The one off the pump will be fine, has tons of pressure. I can almost his the sidewalk with it.
