R/O Water Filter Suggestions

Just invested into a 75 gal tank, and figured an R/O water filter is in need, im new to bigger tanks, what is a good and reliable brand that you all use? and should I buy them off the internet?

Also, when running the filter, should I just run it the day before to get enough water for the water change? How and how often do you all use your RO filters? Sorry for all this, I have no idea how long or when to run a RO filter!

 

I also just got into a R/O ubit and a 75 gallon tank I bought a RO unit off craigslist and it has worked great so far and i got it for $50 so thats a plus. I would look on the sight and see if anyone is selling theirs.

 

If you have an LFS near you, then just get your RO there, theye probably have it for about 5$. If you have your mind set on one, you will need a trash bin to store the water in. As for running time, it all depends on the gallons per day of the RO and what you need, you can make some then store it in a trashbin with a lid. Finnallyyou do not use ro for water changesuse saltwater

 

Spectrapure is one of the best out there and they always seem to have some sort of sale on their product.

Make sure and get a RO/DI unit for making your saltwater. Use the RO/DI water for topping off the tank. You should make at least 10 gallons every time to keep the filter working at its best.

It is one of the best investments you can make for a reef tank.

 

this is the filter I Got RODI 75GPD purely H20 optima and it works great

 

sorry yeah I know not to use ro water for water changes, i left out the obvious salt mixing part, do you just get your water from the LFS? how do you transfer the water? how big is your tank?

 

Thanks! Yeah I wouldnt use ro water for water changes, I left that part out lol but do you keep yours running all the time? or like a day or two in advance of a water change?

 

I make up water a day or two in advance and always at least 10 gallons at a time.

 

I have a 55
I use two 5 gallon salt buckets to transfer the water. My lfs charges .50c per gallon for ro which is what I do

 

If im starting a 75 gal, am I looking at 10-20 gal water changes?
