Green Algea Infested on Glass - Aquarium Advice

JMercer · 10-13-2008, 09:33 AM

the best way to describe this algea is a green felt on the rear of the tank. I usually use a magnet scrubber on the front but because the tanks in a corner i cant reach the back, and as a rule of thumb i do not put my hands in my tank unless its necessary. I have done water changes, i have reduced lighting (6 hours for acetic and 4 hours for daylight), i have blocked all sunlight coming in with eclipse shades, and i feed 1 pinch of pellets every 3 days. I also have some algea on some rocks i first thought was hair algea, but its not as long, and seems to fall under "fuzz". I have read the infamous link regarding combating or controlling nuiscence algea. do i need to just scrape this stuff off and catch it in a fish net?i was hoping for coraline growth on the rear of the tankn and did not want to disturb it so much. I have some small spots of coraline on the glass, and power heads... majority of rocks covered, the rest patches.. what to do i need to do?!?!?!?!?

Setup
65 gallon tall hex
100w Nova T5 extreme lighting (2 acetic /2 daylight / 2 night led's)
75w UV Sterilizer
canister filter w/ spray bar with surface skimmer for intake
2 power heads (one half way, and a nano at bottom behind rocks)
modified Bio Cube Protien Skimmer (14 inch tube)
* dont knock the biocube protien skimmer, my lfs laughed at me until they seen what it can and does pull from the tank.

*Live stock
3 Clown fish
2 anemones
1 unidentified crab (size of a nickle)
2 fire shrimp
1 coral banded shrimp
about a dozen of hermits (blue legged)
4 large snails (2 huge snails)
3 stalks of Xenia
2 mushrooms (hitch hiked on lr)
80 lbs of LR

Water tests (all API Liquid tests@ 11pm)
Nitrite and Ammonia = 0ppm
Nitrate 10 ppm
PH 7.8
Phospahte = 0ppm ( i use ROWA in the canister filter)
Calcium =400ppm
KH = 11 dKH
Salinity 1.022

The only dosing i do is 5ml of Alkalinity once a week, and 10ml of calcium once a week (R-E-E-F Restore). I do weekly water changes with RO/DI water using salt (Tropic Marine) mixed at LFS. all water is monitored by lfs and purchased from lfs.

Can you test the water from the LFS?
Do you have foam/sponges in your filter? If so, do you rinse it in old SW?
Generally, I will scrape the glass the day before my PWC and let the filter suck in all the gunk.

I have a sponge media in my canister, actually 2 types. 1 is a biological mesh, the other is the floss. I test the water from my LFS, i actually switched to another lfs because my main supplier's water had 16-18 dKH and was all wacky. I do weekly water changes with high quality water, and high quality salt (Tropic Marin).

If your question regarding sponges was in regards to live sponge, i have a little that lives in there as well as in my tank.

The algea after a couple days of limited light is turning dark green, light brown, and white in patches so i assume that it may be dieing off. Dont know though... well atleast my snails have a feast.

I rinse the bio sponge (black floss type media) with old SW, and rinse the white floss with tap and allow to dry, i know i need to replace the floss soon
