I've been doing reefing for a while, and have always used an R/O system. Well we decided to sell the reef off, and just set up an ADA I had lying around as a planted.
Now I guess I've just been so used to using the R/O unit that I don't really feel comfortable using tap water, but I know it isn't necessarily bad for planted tanks to do so. But I have the unit, I won't make enough selling it to make it worth it, and I plan to use it when I eventually get a reef again. All filters are pretty much done for, so they would need replacement, but I am wondering what everyone thinks is worth doing.
Should I just replace the filters, and leave the membrane in place, or maybe remove it completely? Should I use the DI, or take that out as well? I don't mind spending $20 on filters if that would be fine.
I really don't like using conditioner, and I am getting the Pfertz high tech+ line up for my fertilizers. The system is going to be high light / pressurized CO2, and well filtered.
