comparisions

I just upgraded my tank after only 3 months lol. Ordered a water box 65.4 and thousands in equipment of course. I did get 2 Nero 3 with the tank which is 48in but thinking about getting a Nero gyre as well or another power head. Any thought or suggestions would be appreciated. Thank you.

When I first got my RO Buddie (100 GPD) with DI cartridge, I paid approximately $70 for the set. I have had it for almost 9 months I've run through the DI about three times so far. I've changed the sediment and carbon cartidge once. Currently, it appears that my DI is not working. It is still...
