No coralline alge on glass tanks?

[jase0723]

Hi folks,

I was wondering, I've had my 55 gallon glass tank set up and running for year and a half and I've not had any pink coralline alge growth on my glass at all not even on the plastic over flow box. I do get a few pink spots on the power head and thats about it. I do get a lot of coralline alge on the rocks though. However, I get hard green alge in "a few" spots on the overflow box approximately quarter inch in diameter. I find this strage because when I used to have an acrylic tank it would be covered in pink and green coralline alge unless I scraped it off on a regular basis. Is this a normal for glass tanks? or could there be something not normal with my tank condition - should I be even concerned about it? In a way it's kinda nice not having to scrape the coralline alge off the glass all the time.

My tank specs are: 55 gallon Oceanic glass tank with 250W MH and 55W PC lighting. calcium reactor, skimmer. Water perameters all seem to be good although my coral growths seem a bit sluggish. I do use RO water with De-ion

Any input would be appreciated.

I wouldn't worry about it. I have lots in one of my oceanic tanks on the glass and overflow box and hardly any on the other oceanic tank, but both have it on the LR. Both were set up at the same time.

in my opinion, they love plastic more than glass.

they also love low light and lots of flow.
also they also love well skimmed water.
also high (recommended) in calcium.

thats why i dont like acrylic tanks.... it is a pita to clean

Hmmm...I've seen a lot of glass tanks covered in coralline algae. Could you list your water parameters? Have you tried scraping the coralline you have in order to spread it?

What is your calcium level? These guys really like calcium. I have had good growth either way with high and low level light....

I'm not sure why you aren't having any growth, but I would venture to say it may have something to do with your Ca levels.

I have a glass tank that I set up about 9 months ago, and this is what it looks like:

I also agree that coraline algae seems to spread more on acrylic tanks.It also does not like strong MH lighting long term.Nice picture above.

Thanks for all your replies.

From what I have read so far I'm not going to worry too much about it. It doesn't seem like a serious condition so far and my corals seem to be ok.

Thanks.

IME, coralline grows with good and stable calcium levels, along with a steady and stable alkalinity. Indirect metal halide lighting , VHO's PCs also seem to make em go crazy.
