How do I avoid algae in a tank ?
Hello,
I am in the process of researching for a new tank (Malawi cichlids) and want to get it right from the start. One thing that bothers me is algae. I have a well-planted tropical tank which does not have too much trouble, but that's mainly 'cos I fertilise it and inject CO2. This new tank won't have any of that, but I still want to make sure I don't get the old green plague. Tank parameters :- *) 220 litre, 24" cube tank *) water will probably be around pH8 and hard (basically I have soft neutral water out of the tap, but am going to use a crushed coral substrate) *) Lighting unknown as yet, but will not be huge. Most cichlid tanks seem to have a blue light and a white light. I assume the white is a normal tube, but no idea yet what the blue one is, nor if it contributes to the light for plants/algae. Due to the shape of the tank, lighting will probably be two 18" or 24" tubes. *) A few tough plants, such as Java Fern, Anubias, etc. Basically limited to the ones that Tropica's site said are safe for veggie fish. *) Water changes will be 10% twice per week. Any tips for how to keep such a tank algae free ? I'm particularly bothered about the plants as Tropica's site mentioned that Anubias (in particular) are slow growing and so more likely to get algae as the leaves hang around for longer. I know the last time I kept one I had very great difficulty keeping the leaves clean. Thanx for any help -- Alan Silver |

Thanx for any help I've kept algae pretty well in check by keeping the lights off most of the time and minimizing the sunlight that hits the tank. Don't overfeed, and a couple of good cleaner fish will help. I get a little algae on the rocks, but hardly any on the glass. HTH, Mark |

Chuck Gadd http://www.csd.net/~cgadd/aqua I haven't had a lot of live plants in my tanks, esp. with Malawi cichlids, but when I have had live plants, I had very few problems with algae. I assumed this was because the plants were using up the nutrients and leaving nothing for the algae. Am I mistaken on that point? Mark |

Well, I would guess that malawi cichlids eat lots of food, and therefore produce lots of waste. And I'd bet that the tank didn't have really high lighting. So I'd doubt the plants really did consume all the nutrients. I would probably bet that the tank just had low enough lighting to avoid algae, and still keep lower-light plants alive.

How do I avoid algae in a tank ?
Use floating plants.
They need no CO2 and require less light since they are ight next to the light. This also blocks the light for the algae. I used Water sprite for my cichlids for many years. If you have light, water and nutrients, something will grow. You have a choice of what. Regards, Tom Barr Alan Silver wrote in message ...

I used Water sprite for my cichlids for many years. If you have light, water and nutrients, something will grow. You have a choice of what. That's an interesting idea ;-) Only trouble with floating plants is that you can't see them ;-) I was intending having some plants anyway, I just want to try and work out what level of lighting is going to be enough to get them growing, without having the algae grow as well. Thanx for the reply -- Alan Silver |

Sherwood writes snip I do not want to add too many chemicals to tanks. Agreed. I don't want to add *any* chemicals. I want to avoid algae as naturally as possible. I added various plants to tank usually the plants will root and the algae has disappeared. That's what I'm hoping. I'm just trying to find the right levels to ensure the plants grow and the algae doesn't. Thanx for the reply -- Alan Silver |
