Algae -vs- Plants
Why is it easier to grow algae in my tank than any live plants? I've got a
29G tank, which has all the essential/default equipment (filter, heater, hood, light, etc), yet all the plants I ever put in there die within a month or less. But meanwhile, the algae seems to thrive, and grows on all the plastic plants and tank glass, and some of it on the filter intake tube and gravel, but not on the heater. The tank is 2 years old, and has an angel, 5 mollies, 10 neons, 3 ottos, and a clown pl3co. TIA! -Geoff |

Generally it means that something is out of balance. Post more specifics about your tank (water parameters, how many watts of light, etc) and people will be able to give you better ideas. Offhand, the usual culprits probably apply - not enough light, and need for CO2 injection. -- www.ericschreiber.com |

A plant is like a large factory. They are slow to start up, but are very efficient once they are operating with a steady supply of nutrients and light. Algae is like a street-corner hot dog vendor. They appear quickly, react fast to any changes in nutrient levels, and are very opportunistic when supplied with strong light. Now consider your operating conditions. In the average aquarium, lighting and nutrient levels are peaky. If you could feed a tiny amount of food 12 hours a day, your plants would acclimate to that level (of continuous fish waste) and should starve your algae. This also explains why smaller tanks have more trouble controlling algae (nutrient levels are even more peaky on a fish-load scale). CO2 is like keeping your plant factory on hot standby ;~), so any nutrients hit the water and they are gone (well... they are more quickly processed). When you hit the right combination of nutrients in the water column (and in the substrate for your root feeders), and the right quantity of light, then the battle to fight algae is sometimes won with reduced feedings, smaller feedings more often, or different types of food (lower in phosphates or ash). Food, heat & light are the 3 inputs you have to play with (ferts & CO2 being a form of food if you need to employ them). Bottom line is lots of light and a stable set of conditions (which you can then tweak), is usually all it takes (with some patience ). NetMax |
