Tap Water?

kcmo lawman said:
Yeah, my tank is almost a year old now. I just recently started having trouble with the cyano. When I do my water changes I use pre-mixed salt water from my lfs, but when I add top off I am using tap water due to the fact that I don't have a ro/di unit yet. I am currently trying to save up to buy one. It seems that for almost the past year I haven't had any trouble with cyano. As stated before it just recently started after I got my new 400w metal halide light. For the first couple weeks the light was on for about 3 hours a day. After about 3 weeks I upped it to being on for about 6 hours or so, and now it is on for about 9 hours a day. I am wondering if the combination of the tap water and my new light is the cause for this.

Thanks for the response,

I'm not sure what type of stores are available in your area, but Wal-mart sells the water out of the machine(callaghan). It cost me only $.99 to do a top off. Lfs's usually sell it cheap too. I can't afford a unit right now, and this works well for me.
 
I finally broke down last Friday and purchased a 6 stage, 125g a day ro/di unit from ebay for a great price. It should be arriving here in the next couple of days. I have cut my lighting period down and will be using the ro/di unit to do water changes and top offs and hope this will help.

Sometimes a change in light intensity can cause the algaes, mainly because light equates into a change in water chemistry. Just a thought :idea:
 
light isn't a change in water chemistry... it just brings out algae that needs a photoperiod to grow.
 
I appologise, I was under the impression that stronger light would infact change the water chemistry by changing the rates in which plant and animals grow and consume and then produce waste that would infact change water chemistry, am I wrong? Sorry if I said something that wasn't acurate. :sad:
 
No need to apologize. We all learn something new everyday.

I have read that you can also use distilled water? Has anyone had any luck with that?

I heard somewhere that it contains trace nitrates. Not sure of its overall effects. Probably worth it compared to using tap.
 
I would hope distilled water didn't have nitrates, its pure water, what is used to calibrate refractometers. I know people who buy it for top offs but not for water changes or for full tank setups.
