Here are some pics of my tank:

I have some cyano bacteria on the green algae for sure. I try to suck it up when I do my water changes. I have some other reddish algae? that is growing on the coral. The texture seems different and you can't remove it with the turkey baster. Is this something else?

I am at the max for fish and that is kind of why I was thinking of adding some more filtration.

I have 1 adult clown, 3 juvenile clowns (locally bred in Victoria), file fish, 2 cleaner shrimp, 1 6 line wrasse and snails & crabs.

Thanks,
Michael

I'm mulling this over.

It looks like most of your corals are softies. You've got cyano, and what I'm guessing is bryopsis (the green stuff). It is difficult to tell from the photos on my iPad. I'm going to have to look at the photos on a computer. If you filter/skim aggressively you may loose some of your corals. I personally can't keep Xenia: it requires more nutrients than my display system provides (but I still have algae and cyano).

You need to pick off the green algae. But, don't let any get loose in the tank. You can't treat with H202, as that will certainly kill your Xenia.

I would definately add a bag of Purigen to your media basket. I would also definately skim.

Do you have any idea what your phosphate and nitrate levels are?

Default 28 gallon filtration

I dont think that is hair algea,its too course,i have some in my tank and it is very fine and flowing.What you have is kind of like cheato which is beneficial,and aids in the filtration.Just keep it trimmed back and you should be good.Run your skimmer once or twice a week.

Now that I've seen the photos on a better monitor . . . it definitely looks like cyano in the green algae. It may just be caught up enough in the algae that it won't syphon out.

Now, the green algae . . . I've had that one in my display. I don't know 100% what it is called, and I couldn't get an ID on it. dbigdog may very well be correct in that it is similar to (or a species of) Chaetomorpha.

My Tuxedo Urchin ate it, and I was very pleased to have it gone from my display.

If it starts to become invasive and choke out your corals, you will want to remove it. Otherwise, if it stays in check, it may be okay.

What tests are you using?

You most likely do have phosphate. My API test always tested "0" for phosphate. I purchased a Hanna Checker, and while they're only accurate to 0.04ppm, it has certainly shown me that I have phosphate in my system. I'm also able to determine that my ROWAphos is removing it (by comparing the tank water to the output from my fluid reactor).

Every nano tank i've owned i've always upgraded to the INTANK media basket. I think its the best upgrade you can do for nano filtration.
Most run floss, purigen and chemipur elite in their media baskets.

happy holidays!

That green algae looks like a sprig I have growing in my tank. I believe my emerald crab ate it though, mine only got about 1/2" tall before it got mowed down. It was either the emerald crab or a snail/hermit.

Hi:

I just tested my water:
Calcium 460
Phos: 0
Nitrite: 0
Nitrate: 0
Amon.: 0.1
PH: 8.1
KH: 14 dkH (a bit high)
SG: 1.025
I am using Reefer's Best Salt

I am thinking of adding a protein skimmer. After reading a few reviews it seems the Aquamaxx HOB-1 is rated quite highly. Everyone seems to be out of stock and the only Canadian Dealer I found was reefsupplies.ca

PS. Is there an easy way to "insert" photos into the post from my computer directly? I know it can be done on other forums.
