i just found out that a guy who works at same place as me has marine tanks set up 2 or 3 i think, he is a very keen aquarist and really seems to know what he is talking about. Now he has told me that he doesn't use RO water in his tanks (as our water supply is very good) and has no problems at all with algae or anything else associated with water problems. his tanks are reef set ups and uses something called the berlin method, now as i am in the same area as him, what do you think, could i avoid having to use RO water. any advice on this matter greatly appreciated..............

I am not a marine expert, but I believe the main problem with tap water is phosphates (right guys?). Perhaps you should ask your friend if he has ever tested his tap.

Hopefully someone with more marine experience can help you with this.
 
Doesnt matter how good your water is, if it comes out of a tap it will be loaded with chemicals. In my opinion Berlin is ok for large setups, 1kg of LR for 4 litres of water. For the sake of a few quid for an RO unit why take the chance.

i forgot to mention that he does use phosphate removal pouches of some kind

i'm not suggesting not using RO water, i was just mentioning that its working for him although i doubt its " only a few quid " when you have say a 240l or larger tank plus a sump of say another 60 or 90l. in all probability when i get set up i'll making my own RO water anyway
 
I have never used RO in my tanks... Took a few years to work out the kinks, but I don't plan on switching to RO. I don't advocate using tap either as it has its challenges, just adding my experience :good:
 
Well, I'm one of those awful people who has used tap for new salt mix, so I'll toss in my 2 cents on things I have to deal with out of the tap other than the usual ammonia and chlorine combinations...

Things to watch out for:
-Phosphates as already mentioned - removable biologically and chemically
-Carbonates - tricky to handle sometimes, as it can throw off pH unless handled carefully
-Metals - can be chemically dealt with
-Nitrite/nitrate - these should NOT be in high abundance in drinking water intended for human consumption, but I regularly picked them up from city water when I lived in Texas (especially nitrite) in bothersomely high amounts a few times. Needless to say I tended to stay away from drinking water from tap a lot of the time when I lived there. Hasn't been a problem since I moved to New England (water actually tastes like water up here lol) and I've never heard anyone complain of either of these out of a city tap in the UK.

Things that aren't big issues but are often present:
-Fluorides - I have read no adverse effects on inverts except at high concentrations (from toxicity reports).
-Trace amounts of various other minerals
-The occasional bacterium or virus, which is not really an issue for sw beasties

I've read some claims of medications and things being picked up in tap water in various places but I have yet to read an actual scientific document proclaiming it. I'm sure that the occasional molecule floats through but whether that would actually harm anything is up for debate. In the past I read some other reports about hormones coming from some kind of runoff affecting sex ratios in invertebrates and getting into water supplies in the area, but unfortunately offhand I can't remember where I read that or what areas were involved.

Bottom line is that it's best to find out what's regulated and deliberately added along with what the local stats are. If you don't want the added bother associated with using tap or if you find out that you're in an unlucky place with icky water, then it's obviously far better to use RO.

Hold on Steph.... after all that "Trevor don't tell anyone i don't use RO" you just go and spout it in some thread on here? Hahaha... Sorry to hijack the thread to berate steph...
 
I don't use RO either, again.. some kinks at the start, but now no problems after sorting those out. RO is not easily available here.

as a matter of interest what kind of problems did you encounter and how did you rectify them
 
Problems include what was mentioned here. I had major algae problems for a long long time. I also run carbon constantly.

haha Trev. :p

^ ;)

Mainly nitrates, but I use Nitrazorb on the new water before adding salt, and the old tank water for removing it from the pouch.
 
Seems like the debate is split.

Iether buy an Ro unit and produce your own water

or

Use tap water and chemicals to neutrilize what is in it.

I think over time the cost of additives will well outweigh the cost of an Ro, and personally the less I put in the water the happier I am. :)

Everyone to their own though :good:
 
this might come across as really stupid, but can you drink RO water? obviousley not the salted stuff lol
 
You can ;)

Myth #1 - Reverse Osmosis Water is Unhealthy to Drink
Truth: Reverse Osmosis water is very clean and good for our bodies.
Reverse osmosis has been called dead water because of its purity. Detractors say it is man-made, unnatural and unhealthy. They claim that RO water can only be used for industrial applications and not for human consumption. They say that RO water is too pure and clean to be good because such perfectly clean mineral-free water does not exist naturally on earth. They forgot about a little thing called RAIN.



Rainwater is water that has been stripped of all minerals and is one of the purest and cleanest water on earth. Human beings have relied on drinking rainwater for thousands of years without any negative health effects. Only recently has rainwater been polluted by the industrial age and man's pollution of the skies. Ask yourself this. What can be more natural than mother-nature's life giving rain?

With all the scientific research that has been done over the years on reverse osmosis water, none has ever documented any negative health effects from water treated by this method. In fact RO technology was actually invented by the US military and our military personnel still use it currently for drinking water.

Some more facts to consider.

1. Bottled Water = RO Water
When you drink many brands of bottled water, you are actually drinking RO treated tap water.

2. Soft Drinks = RO Water
When you drink soft-drinks and soda, you are drinking mineral-free treated RO water. Vitamin water, sports drinks & energy drinks are also made from RO purified water.

3. Tap Water = RO Water
Some US city and municipal water facilities (Orange County, CA) are already providing RO treated water to their communities. Los Angeles county is also considering RO systems as we speak. Even Beverly Hills 90210 is using RO water. Hey if reverse osmosis is good enough for the OC and the Hollywood elite that must tell you something!

4. GE & DOW water = RO Water
General Electric and DOW chemical are two of the largest and most respected companies in the scientific community and both sell and endorse reverse osmosis technology for drinking water.

5. Arrowhead & Culligan water = RO Water
Arrowhead, Culligan, Aquafina and Dasani are just a few brands that sell reverse osmosis water.

6. Google Campus Water = RO Water
Google employees have on-site doctors, massage therapists, nutritionists, yoga classes and volleyball courts at their finger tips. They also have delicious reverse osmosis drinking water too.

The truth is many of us have been drinking reverse osmosis water all our lives without even knowing it.
