as i have posted before the problem i have in my marine tank .. i had a Brown algea problem within my tank and went a brought Clearwater the pouch you put in your filter to try and solve this problem .. i tested all my water before i put it in and it was fine .. i just couldnt understand were this brown algea is comming from .. so now i have put the pouch in the situcation does not seemed to of improved. i have tested my water and all seems fine .. i have done a 10 gallon water change and still this brown algea is there ..
things i have tryed 1. Water change 2. tested water 3. placed a remover pouch in and still no change ... the only other thing it could be is my lighting but i have 2 t8 tubes running One blue and one white i do have 4 but have turned the other 2 off to see it this was the problem is brown algea lack of light and green is to much or is it the other way around can anyone help me here with what is causing this |

tom im not a marine keeper myself but if its a new tank doesnt it have to pass through the brown algi stage? will it not right itself in time?
hope some of the marine guys can give better info to help you ! |

| 27-02-2007 00:22 by tomdoc |

Tomdoc,what did you test for |
| 27-02-2007 08:55 by LarryC |
I have the same problem it is covering everthing, i stir the sand and that helps that but the rocks are a problem, ALL the readings are normal anybody can help us please |

i take it u r using ro water for water changes,my set up 4mnths old and had that problem so just added a phosphate remover like rowaphos or seachem and it cleared up after a few weeks. |
| 27-02-2007 09:59 by tomdoc |
i have tested for nitrate nitrite phosphate PH salinty and yes i am using ro water all the time have never used tap as said before this tank has been running for over a year nearly 2 |

you should not stirr up your sand as it release deadly toxins beneath it and can also be the cause off your brown algea as the tank start its recycle afresh my tank is 8 months old now and i still have the algae cycles cycles repeating itself best keep your glass clean and let it go through its cycle wich should clear up after 8hours |
| 27-02-2007 11:21 by JOHANSWAN |
sorry not 8 hours it shpould be 48 hours |
| 27-02-2007 11:37 by tomdoc |
thank you all for your imput but i have tryed all this .. i think im going to cut down my lighting and see if that helps |

How many grazers have you got? I would suspect not enough I am currently experiencing a similar problem but that is because I have upped the number of fish without upping the number of grazers I currenlt have 7 turbos and about 10 hermits as my clean up crew in a 55 gallon reef tank far below the required number ideally I would have about 30 turbos and a similar number of hermits. QED this is my problem.
As far as your problem goes firstly how long have you been running the flourescents they need to be replced every 12 months as they go off spectrum and favour the red end of the spectrum resulting in ideal conditions for algae. Also how much skimmate are you getting and is there a slight yellow tinge to the water (test this by turning the lights on the tank out and half submerging a white plate if the submerged half looks yellow the organic load is high hence your problem again this is an issue I have on my tank. Also do you get much coralline algae growth? If not look at your calc and alk make sure it is right and get the light out put high enough to prommote its growth as this will inhibit brown algae growth by taking up valuable nutrient brown algae will use. Really all I can suggest is check the age of the tubes. Up the grazing pressure perhaps try the super grazers that www.stm-shop.co.uk sell these are like turbos on steroids. Look at the bio load on the tank is it to high? If so how can it be reduced i.e. reduction in food for corals removal of juices from fish food. Up the number of filter feeders you may find on the underside of your rockwork copious numbers of sponges. Just as a side note I have a nitrate level of less than 0.02 ppm phosphate of less than 0.02 ppm and I still have brown algae under 2 x 150 watt 50,000 kelvin bulbs. |

Make sure you always have a phosphate remover in the tank forgot to mention this prevention is much better than cure it took me 6 months to recover from a phosphate problem in my early days of marine keeping. It was made worse by using canister filters! |

the light i have just changed about 2-3 months ago and the plate test shows it as being non yellow i currently have 9 turbos and 15 hermits |
| 28-02-2007 10:23 by Alan |
How bifg is the tank 9 turbos and 15 hermits doesn't sound like much I would up the number of turbos. |
| 28-02-2007 22:52 by tomdoc |
the turbos are very big and in a trigon 350 |
| 01-03-2007 09:38 by Alan |
350 litres so 78 gallons.
As a minimum I would go for 35 turbos and 35 dwarf reef safe hermits. How many fish do you have in the tank? And what other inhabitants do you have aside from corals as these will consume nitrate I suffered a nitrate spike after rehoming my huge pussey coral couldn't believe it. Nitrate went up from 0.02 ppm to 5 ppm its come down again though thankfully. |
| 04-03-2007 00:03 by tomdoc |
well i do not have any corals due to my lighting t8s i have a fish only setup at this tome with live rock |
| 04-03-2007 00:05 by tomdoc |
and i have 7 fish and my tank is the trigon 350 .. i think water movement could be the problem and im still only running the jumbo filter and no powerheads so im going to buy some powerheads n get the water moving |
| 05-03-2007 10:26 by Alan |
Water movement is definately your problem you are goiung to have dead areas in the tank where detritus is going to have built up to a horrendous extent.
Aim for a flow rate of 9,000 lph and you won't go far wrong the fish will love you for it too. Go for Tunze or hydor and if your on a budget go for seio or marea the later can be bought on line from www.stm-shop.co.uk |
