Why would tap water make it worse? Isn't that what they provide these checmicals for to produce ocean water from tap water?

The instructions on the salt bag say to treat the water for chlorine and chloramide, buffer the PH then add their salt and wait for it to be fully absorbed.

Their claim is that it is almost impossible to distinguish it from natural ocean water, plus it has the benefits of trace elements being present.

Is this wrong??

Generally, tap water contains PO4, wich is then introduced to your tank. PO4 is a main cause of cyno. Using RO/DI water can greatly reduce the PO4 in the water. A DI unit is suppose to take it out completely.

Yup, adding a DI to my unit was a big part of curing my cyno problem.

If a FO tank how long do you have your light on for? As others have said I would cut back on your lighting time also. What type of bulbs are you using? And what kind of lights... Just curious.
There are a lot of good fixes the others have mentioned.
As mentioned PO4, low flow and lighting spectrum all help it grow. That PO4 is a pain in the butt.
Good luck in the battle.

I myself have had to deal with cyano in my fairly young 40gallon. I did run a skimmer, but it was a junky one. I upgraded to a cpr bak-bak 2, and within a week 90% of my cyano had dissappeared completely. I have a little patch remaining in a back corner which has very little flow.

I do realize that reef's can be skimmerless and successful..however a skimmer will make life so much easier. $250 isn't cheap, but looking at the rest of your setup, $250 shouldn't break the bank. 99lbs of live rock (at least for me to get ahold of) would easily be $350-$400. So don't rule out a skimmer for your setup. Save up, drop hints to family since christmas is coming up soon.

Now I know that the cyano is a red to maroon kind of slimy covering type of materail, but what is the burnt orange/red filmy stuff that covers my sand and the walls of my fuge? How slow would the flow have to be to be considered a dead spot because all of this bacteria/algae waves in the water like my macro everywhere it is at. From my last test results All my readings are 0 even P04. And I use RO/DI water everytime I do a water change. Any ideas would be appreciated.

I have reduced my light times by 2 hours. I hope this doesn't adversely harm the corals too much?

I am getting a wave maker this weekend and I think I might buy another smaller powerhead to help remove some of those dead spots.

I think a skimmer would be great as a Christmas present actually. What a perfect idea!

I just picked up the Natural Wave wave maker from Aquarium Systems. It has three cycled timers, two that alternate and one that goes on and off at a slower speed then the alternating ones. Plus three normal outlets. I added a third Maxijet 1200. I am now thurning over 1600 gal/hr on a 72 gal tank. Trying to eliminate the dead spots. The Chemi-Clean took care of all of the cyno on the sand and most of it on the rocks in less then 48 hours. I just doesed it again to finish the job. Victory will be mine!

The chemi- clean by Boyd will clear it up, BUT you have to retreat often if you don't fix the root cause. I have been battling it for months and have treated with chemi-clean three times and since I can't find the main problem obviously I still have it. I have changed the bulbs, added powerheads, and started making my own food. I guess the only thing left is to start buying my replacement water. What a pain in the old A@#. It has cut way back since I started making my own fish food though. By the way, I bought my chemi-clean on Ebay.
