Bluegreen algae, Nitrate/phosphate/ lightrelationship? 3/30/08 Greetings all! Some back ground on the issue,hope it is not too much for the basic questions I have: I service a 90gcichlid aquarium, currently has 6 med size fish, 2 pc driftwood-I readthis may be an issue but was not in the beginning. pH runs 7.2-havebeen bumping it up-was originally set up with regular aquarium gravel,NO3 is 0-5 , 3 dKH- may rise soon as have been adding cichlid substratetemp 78. No ammonia nor nitrites.. I average 30-45% water changes.. hasan Emperor 400 type filter.. I recently added a Magnum HOT filter andhave been using HBH phosphate pads since mid Feb.. An automatic feederwas put into service also in mid Feb, prior the tank was hand fed..quite possibly over but it never showed up in the NO3 tests..... I havebeen servicing this aquarium bi-monthly for the past several yrs withbasically no problems. When I first started it had a UV sterilizer thatwas not utilized and the tank two ends were covered to prevent lightgetting into the aquarium. It appears as though there is a light on 24/in the same room as it is in a nursing home. It did have a removablefront cover to give the aquarium darkness, but somehow the cover walkedoff long ago... Last May I removed the end covers as it make the tanktoo dark IMO and the residents could view the fish from the ends aswell.... Last Oct the tank started getting blue green algae- Cyanorather badly and quite suddenly.. I was rather slow to react.. I onlydid large water changes for the first few months, to no avail. Ifinally understood this was basically like the Cyano in SW aquarium soI started using Phosphate pads, increased flow by adding a powerhead-and started adding the cichlid based substrate. In mid Feb the feederwas installed as I believe that more that one person was feeding theaquarium..... Since I started this regime, the tank has and isimproving significantly..... however the client and I have somewhatbutted heads over the cause and how I should have addressed it... Ishould also point out I service 2 other aquariums-ones that I set upabout 2 yrs ago with aragonite sand or cichlid mix , using the samewater source and have had no problems.

Still water that's low on oxygen promotes blue-green algae growth. A device that disturbs the surface of your tank's water, like a trickle filter or a decorative fountain, helps better aerate your underwater world. Other devices are available for this purpose too, like airstones and bubble wands, and many are made to look cool. Also, if your gravel or other substrate's getting clogged with gunk, it's not getting enough circulation between the cracks, which promotes algae blooms toward the bottom of the aquarium. Use a substrate vacuum at least every few days. Also, you might be going too heavy on the fish food, leaving leftovers sitting in the substrate; feed your swimmers only as much as they eat without taking food into their mouths and ejecting it, once daily.

This is not an uncommon occurrence, nor are these actions unreasonable, given the information that most aquarists have. For all intents and purposes, this seems to be some sort of algae outbreak. Even its name, "blue-green algae" says so. However, it isn't an algae. It's actually a strain of bacteria known as (its name derived from its vivid color, which would be beautiful if it didn't signal so much trouble for an aquarium). In addition to blue-green, cyanobacteria can be black or even red.This menace is none other than Cyanobacteria, often referred to as blue-green algae in freshwater tanks or red slime algae in marine tanks. Cyanobacteria is one of the oldest living things on the planet with fossils dating to 3.5 billion years ago in the Achaean rocks of Western Australia. This is one resilient life form, but why has it been so successful? Simple, it makes use of the light waves that are discarded by higher plant life, lives in a wide range of temperatures, and subsists on organic waste materials including dissolved phosphates and nitrates. What do all of these things have in common? They are readily available in the artificially constructed environment of the home aquarium. Although it is not dangerous to the inhabitants of a freshwater or marine aquarium, Cyanobacteria can become an unsightly mess that can cover every surface of a tank in a matter of days.
Which algae do you have
Aquarists will encounter four main types of algae. These are diatoms; red algae, a group that includes brush algae and hair algae; green algae; and blue-green algae, more properly known as cyanobacteria.Probably the best all-around algae eaters are Nerite snails. They constantly graze algae of all types, except blue-green algae, but do not harm plants, stay small, and don't breed under aquarium conditions. Allow 2-4 snails per 10 US gallons.
