Budget doesn't exist in this hobby: Brian's 45g Build

[Etaloche]

As I mentioned I managed to paint the back before falling asleep again.



No mess this time



Also went and picked up this RO/DI unit from a member here
It was $50 and just thought I'd give it a try. Was expecting a simple 3 stage unit but I think this is 5 stage?



Was told that the DI filter and the RO membrane were almost new when it was taken down.
The unit hasn't been in use for over a year though. Are there any precautions I should take to flush out the system before using?
I'll have to add a TDS meter, pressure gauge, and possibly a flush kit in the future.
