I converted my tropical community tank to Tanganyikan's a few months back and have about an inch of corral sand as well as ocean rock.
My Phosphate reading is below 1 (nearer the 0.5 mark) and my nitrate is about 5. I have tested this and got the same results with other test kits. I have some hair algae on a piece of bog wood and have put 2 bristlenose catv fish in as well as the Tanganyikan's so that they can deal withn it. I do seem to be experiencing a few problems and was hoping that someone could help me out..... I seem to be having an issue with the corral samd going green on one side of the tank and this then covers to the other side, and my ocean rock starts to go a dull green and brown colour, making it look a little odd. Is this normal (looking at other peoples tanks, their sand is the natural colour)or is there something that I am doing worng or not doing at all???? I have a nitrate reducing resin in one of the 2 fluval 405's on the tank and a phosphate reducing resin in the other 405. I replaced these a few weeks ago so they are not exhausted (readings confirm this). Please help........... |

I do the weekly water changes and the other readings are what the local shop advised (buffers/ph/temp/etc).
Help......  |

is your tank located near a window
it could be gettibg to much sun light  |
| 22-08-2007 23:08 by Nick G |
No, located out of direct sunlight, and the lights are on for about 7hours per day |

hi nick is it the bogwood causing it? dont Tanganyikan's like rocks alone?
and keep your eye on the plastic under the clips on your fluvals the plastic on mine snaped without warning looking at the other clip it showed a white weekness mark ......be warned and keep a eye on them mate |

Will keep an edye on them. Really don't know why the corral sand goes green though, is this normal? |

hi
dump the bogwood?? it will offset the coral sands buffering. algae needs light and co2 as well as a food source, just because you have low phosphate and nitrate levels doesnt mean there were not any there BEFORE the algae used it to grow? , if you have a very well lit well planted tank and over feed a handful of oscars they foul the water just the same as if you dont have a well planted tank its just about how these chemicals are removed from our tanks.  |

What do you suggest I do |
| 23-08-2007 09:28 by nick2906 |
Hi Nick, i found i suffered from it a little bit if the tank had received too much light and if id over fed them, i only have the tank lights on for around 4/5 hrs per day and now feed quite sparingly
Do you have any pics of your rift tank? |
| 23-08-2007 09:31 by Nick G |
I'll have to take some and will try to put them up. Just want to sort out the problem wil the corral sand going green |
| 23-08-2007 09:37 by nick2906 |
let us know how you get on mate, ive never had the coral gravel go green before, one side which catches the sun will get a bit of brown but thats only about 2mm deep and i simply clean it out, ive found good water changes help, my fish have thrived off it
keep us posted how you get on mate |

check your phosfatelevel and the bogwood will be the culprit for spreading the green algea |

Going to remove the bog wood, but as I said at the top, phosphate reading is low. Still confused though |
| 23-08-2007 10:39 by Woz |
i dont think the bogwood will be the root of the problem, ive found myself in an extremely simialar situation, in mine the coral sand was going green on one side of the tank and the rocks were going abit off colour, all my reading were fine including the ph...all i did to sort it out was to get around 10 more bristlenoses in the tank to stir the bottom up abit and get another filter to get the flow going abit more, the greens now gone, i still have alittle bogwood hidden in the trank for the bristlenoses as the need to rasp on it to help with their digestion...mines also a tanganyikan tank...is the filter on the opposite side of the tank to the algae? |

You rock woz... |

The phosphate level seems quite high to me - I would try to get it below 0.3 also Phospate is difficult to get accurate test kits for - D+D is the best affordable one. |
| 23-08-2007 11:57 by Woz |
full of useful info perky....haha |
| 23-08-2007 18:42 by Nick G |
Got a filter at each side of the tank |
| 24-08-2007 20:40 by Nick G |
Still open to suggestions |

why dont you try mixing the coral sand with a darker substrate but personaly i dont use coral sand as the fine particals can iritate the gills in my tanks i use african substrate its not cheap but it really is the buisness as for the algae on rocks you can use this to your advantage if you have algae eaters best example tropheus |

Are you moving your sand around during your water changes? |
| 25-08-2007 14:20 by telboy |
when you do a water change do you move the sand ie get ya hand in + bring the bottom of sand to top! also have you put the rock ontop of the sand? as this can lead to aenorobic conditions ie dead/poisonous spots in the sand,invest in a gravel syphon + use that to do ya water changes,also as it seems to be on 1 side is there another light source of anykind?ie table lamp,sunshine? |
