I'm using my tap water for my tank. Now before you go nuts, I have a general ionics softner and RO system. This should be fine for my watersource right.

Why not get a TDS meter and test it? Then you will sleep well at night after you have invested possibly $1000s of your hard earned money.

it will be fine I have the same thing through culligan...no phosphates in my water its perfect and my open brain and my two torch corals are better then happy in my 55 gallon reef!!!!...go with it...I also do 6 gallon water changes every saterday

I would suggest you both get a tds test done.It is not a good idea to make recomendations of this nature when the operational capabilities of the filter and the original water conditions.If this culligan filter is such a good thing why in over 25 years of salt water experience are you the only two I know of who have one.To what standard do these things filter water?Do they remove chlorine?chloromines,slic ate,heavy metals?

Mine is the same company that filters the water for NASA. Im a much larger scale. Its suppose to remove everything including anthrax

[Arnold40]

It may be the same company that filters water for NASA but it probably isn't the same filter. I don't know your income but I would bet that the government has a bigger water purification budget. Invest the small amount of money to test the water so you will be sure.

Native: There are more people that have these type of filters. I removed 2 of them last year doing Kitchen remodels.

HEY! Culligan Man! Hahahaha

In all sincerity guys, just test and make sure its ok. If its not OK you might not find it out for 6 mos and then its too late.

I think your confused. Its not one of those little screw on the faucet filters. It goes threw a charcoal filter that stands about 4 fee tall, then threw a RO system. Also uses about 160lbs of salt.

Yup, they have been around for 30 years. Since Native is 104 years old he will probably say longer.

[NATIVEVAMAN]

Corey, I am not 104,I am much older than that lol.I looked up your ro unit last night at a dealer site.It say they remove chlorine odor and large chunks like rust and sand.Now I have to say that dealer sites are not the best place to get info,but I couldnt find a web page for them.

Here ya go this is the RO unit I have.Micromax RO Drinking Water Filtration System in CANADA

Looks good! It would be prudent to test it and make sure the water it produces is good enough for your tank.

Red Sea Marine Lab is this kit everything I need.

Those are all things you will need to be testing for but we are talking about the water you use to mix your salt with before you add it to the tank. You will need a TDS meter ( total dissolved solids) They run about $25 on Ebay. You can get an inline meter that measures TDS as it comes out of you RO/DI or a portable one that you can test water anywhere with.

why not just take a sample to your LFS and have it tested, that should settle the debate

Good idea! Only I would have 2 stores test it. Someday...hopefully some of you will understand what it is to put a thousand hours into this hobby and thousands of dollars. Leave NOTHING to chance. If you do sooner or later your equipment will be on sale for 20cents on the dollar and you will be giving livestock away. Happens everyday.

i hate to admit how much i got tied up in mine and it's a goldfish bowl compaired to most of you guys

[bnhaus]

Testing the water is key as you can see by the other posts.

[DEWAYNE]

man, you guys are deep LOL I do agree the water needs to be tested even if you have top of the line water purification. just my 2 cents

My water if fine I paid 4thou for my 4 stage ro unit thats through culligan almost 6 years ago now. I have kept corals here the last 6 years no problems!

I paid $5000 for mine

It is my understanding that distilled water has absolutely no (KH) therefore no buffering capabilities causing large swings in PH.Is this also true for RO/DI water?? Can anyone shed some light on the carbonate hardness of RO if any? Heavy metals like copper found in most tap water will KILL corals but not fish.

[capitalb]

Yes...Distilled water has 0 (KH)causing large swings. RO has 8 dH creating much more stability. RO would be my water of choice!

[Br14n55reef]

my ph doesent swing it sits right at its lowest is AM 8.1 its highest was 8.3 but in the PM...this tells me so its called a pin point pH Monitor I bought it from drfosterandsmith.com....b ut yes your right capitalb there is no KH in distilled water..I have used this water for 6 years with no problems!
