algae info

[DC5]

Hi all! Does anyone know of a good site that gives some detail info of algae with photos of what it looks like?

Tank starting to have an outburst of algae growth, I think mainly was because I changed my lighting to PC 96 watts for my 30 gallons. I reduced the "on" time to about 7 hrs now, and my nitrate is around 10 ppm. Also I am starting to change water every week, but that doesn't seem to correct the problem.

The algae that I want to get rid of stays the bottom of the substrate forming a mat, it is dark red/brown in color, and some get kinda big that looks like seaweeds that floating in water while it's anchor in the substrate. Are theses red slime algae?? [smiley=help.gif]

Check your water quality. Are you running an r/o? If so, how old are the sediment/carbon and membrane? cyno, hair, and I believe even bubble algae are nutrient fed. Water changes are fine but if your using tainted water your throwing gas on the fire.

i read something about that is it like a mat of it in the corners of your tank if it is it is from not good enough water movement all it is is bild up---- do you have a sump????? power heads and how big of a gph do you have???????

Yes Cynobacteria can form a reddish or greenish mat either on the substrate or on your L/R. It can even move onto the coral. Water movement is important also. You want to have a water turnover rate of at least 6 times the volume of water/Hr. So if you have a 55 gal. tank your turnover should be 55 X 6=330GPH. Also you want to take into account the vertical pumping action ie: {head}. The general rule is to add about 20%, in this case 20% of 330=66. Adding that to the original 330, you get 396 or approx. 400 GPH. That is the size main pump you would need.
