Well Ive decided finally get a RO unit and WOW is there lots of choices...

First question I had is do I need a DI unit? Doesnt the RO process remove minerals/cations anyways? And is RO enough for a planted tank?

Ive had constant algae and diatom issues (for months) and I want to rule out my water. I think this will be a good step to make consistent water.


Also, has anyone tried that aquaticlife RO buddie? Its only like $70 and seems it might be very useful, any tried it?

I have a Spectrapure unit. Very good quality.

RO only will not removed dissolved gases including ammonia. A DI resin will remove ammonia. That is why I originally got my unit. I have a significant amount of ammonia in my tap. However, I got tired of the $$ for the DI resin. I now just do a 50/50 tap/RO mix to soften my water. Long term RO is much cheaper then RO/DI. I actually replaced the DI cartridge with an extra carbon filter. I dose prime and it seems to bind the ammonia as Seachem claims until the plants and bio filtration does the rest. I sadly know this because I recently killed a Ram with ammonia poisoning after using a different brand water conditioner.

Whatever you get, make sure you get good sediment and carbon filters. Otherwise, the RO membrane will not last long and that is much more expensive than good sediment and carbon filters.

If you don't care to soften your water, I'm skeptical a RO unit would be a good buy or help with the algae. However, I do not have your tap water so can't say.

Anytime, I searched for a good one for months. Mine does awesome and looks just like the expensive ones. My buddy has one that is the same filters and has a fancy sticker. Exact same build and construction.
