red algee? (maybe)
Well i am sending pictures the first picture is of the tank 1 month after setup. The second picture is 2 months after setup (now).

You will see in the first picture the large green algee problem. I have done about 70 gal of water changes in small amounts over the past month.

Now in the second picture you will notice a red something maybe algee problem maybe not a problem I don't know. it is really a pretty color, but I don't know about it. very low on the glass has the red color, and also on the sand. There is also some on the live rock, but not very much on the rocks.

Water Quality just tested

PH 8.0
Nitrites 0
Amonia .25
Nitrates 20

Now this is interesting to me I asked my LFS they said that I am doing water changes to often. I didn't ask about the red color. They said that is why the amonia is there and why the nitrates are not brakeing down. I don't know about that but well what do you think

I was doing about 8 gal 3 times / week for that month in a 90 gal tank.

1. about the red color
2. about doing to maywater changes
3. do I stay on the same water changing schedual do I cut back?

It's called Cyano bacteria. It's caused by , the same thing that causes your algae bloom. To much nutrient. Not enough filtration, way to little flow. Cyano is almost a sure sign of to little flow. Since it does not attach like algae it simply blows away. Get it? Enough flow and you'll never see it.

how do I add filtration?

please read the last post also

do I stay on my same water change schedule that I was doing?

I would plan on large water changes once a week. Like 50% if possible. I'd look into getting a stream pump instead of the MJ's. I used to preach Tunze, still do and then Seio, however things have changed. I now am really excited to say that Hydor makes a new pump ready to go out of the box for less then $50. It is called the Koralia. It is a stream pump that includes magnet mounts. The Tunze nanostreams have been getting some seriously good reviews, a decent price but availability sucks. There is a huge waiting list as they are that nice. At this point the Hydor units look a little better then the Seio's as the Seio's have a huge mount. MJ's don't make good flow in a tank. It is to direct. stream, or prop, pumps have a huge outlet and even though they can move thousands of gallons an hour, they do it gently. I'm curreently having a similar problem. I run almost 3,400gph through my 75g, but as my corals have begun outgrowing the tank they block the flow. Their branches are getting in the way and I'm getting some patches of algae at the bases of each coral.

Things that will help. A phosban reactor or 2. Stop feeding the tank all together. Water changes. A good skimmer. Disposable amounts of carbon. Carbon is exhausted quickly but could be used to help quickly rid the system of unwanted nutrients. Run a phosban reactor with some ROWAphos in it and another reactor with some carbon in it and a bag of Purigen. Pull the carbon reactor out every 3 days and toss the carbon out and replace it. The Purigen is good for about a month and then can be recharged and reused. A heavier skimmer or your skimmer run "wet" will also help.

what is a skimmer run wet?

When you turn it up so that it fills the cup with a heavy liquid tea instead of pudding. Think of it as removing waste even faster.

I can do 30 gal water changes once a week what do you think. I don't have a way to mix 50 gal of water at a time.

Also How many times do I need to do 30 gal water changes?

Water changes alone wont do it. If you leave any cyano in the tank it will come back. While doing water changes get a few power heads to get circulation in the tank. I wouldnt recommend that big of one do them over a week. You could stress you tank by doing such a large water change.

Boerneman does 95% of a 240g weekly and is considered one of the top 5 reefers in the world. Right there with Meleve, Sanjay, Calfo.
