It's kinda fun to play with. I have to go manually enter the ca/alk/mag/po4/nitrates and others if I ever tested them. It will graph those out too but they're not done enough to get as cool of a graph. But it also has a note section where I try to go enter general notes like water changes, pump changes, pump cleanings, bulb changes, etc. then I can go look back at how long it's been. It also has fish/coral data entry but I haven't got to that yet. I also haven't set it up for remote access either.
