RO/DI

Thinking of buying a device to make my own. What will it filter and what wont it filter? Will it have any effect on PH? Our well water is insanely alkaline and full of minerals in such, will it still work?

How long does the filter last before needing to be replaced? Once that time hits do you have to buy a new one or just replace part of it?

When i got my unit i was told to replace the filters every 6-12 months depending on amount of use and the DI filter after 5000 gallons(i think thats right) so i figure ill replace them all at the same time because mine isnt on that much

get one with a TDS meter or add them then you can see whats going in and out of the RO Membrane, and whats going in the unit and out of the unit, that will tell you when they need to be replaced. It all depends on the TDS coming out of your faucet

Well I don't want to waste money on one if it wont take care of that. Our well water is terrible, PH is really high, all kinds of floaties,minerals, and that kind of stuff.

It will take out minerals and impurities. Its the whole purpose of using Ro/Di for reefs. Get one.

You will have serious problems if you dont use ro/di water. There are a lot of things in water you dont want in tank

I use RO DI water, I just don't feel like buying it anymore. Will it lower my PH as well?

Why do you have high ph? And whats high?

And if you dont feel like buying it anymore then i suggest your own system. I put it off for years before buying one but god **** am i glad i finally did. No more hassle running to get water, saved money and you are the quality control. It pays for itself within a year. More like 6 months.
