Leaving my algae in the dark
I am trying to control stubborn algae by darkening my tank, I have the light off and tinfoil around the sides. How long should I expect it to take? Does it really have to be that dark? Is the few minutes I have the lights on to feed the fish a problem? This is the third day and so far it doesn't look like there's any change. --- Outgoing mail is certified Virus Free.

you might need to put black construction paper over the glass so little to
no light gets in at all. |

When I did this some years ago, I was advised to block out ALL the light. Use very thick paper and make sure you paper over all cracks. Don't unwrap the tank for at least three days. Your fish will be fine, so don't worry about feeding them. Leave the lights off too. HTH -- Alan Silver |

I've kept the tin foil on for four days now, I think I will take it off, do another round of tests and then when I think the plants (the ones I want to keep) have had time to recharge, do another change and a round of darkness. Maybe two weeks? --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com). Version: 6.0.491 / Virus Database: 290 - Release Date: 6/18/03 |

Try using thick trash bags etc, cheap and big.
Turn off CO2, increase surface turn over, do 50% before and after water changes and you should not need more than 3-5 days to beat it back pretty good. Some algae will not be affected much, most will. Trim off any left overs, dose well and keep dosing in the future/keep the CO2 high etc. Regards, Tom Barr |

Leaving my algae in the dark
I had an algae problem before that i dealt with by pulling up all my
plants, trashing the ones that didnt look like they were in decent shape, rinsing and cleaning the other plants ina mild bleach solution, and taking out my decorative rocks and cleaning them in the solution too. After rinsing everything, doing a big water changes, and sucking all the crap out of the substrate that i could find, I put everything back in, and made sure my plants were outgrowing the algae after that. Seemed to work fine for me, so it might be a little easier than blanketing the whole tank!?!? just a suggestion Connor |

Tom,
You used to suggest to add good amounts of N and P to the darkened tank. I followed your advice two times and it worked great. Now I see that you just suggest 50% water changes before and after ther black out. I bet that would work too, but adding N and P seemed to work very well. The plants accumulate the nutrients in the dark but the algae can't, right? So a nice big water change after the blackout really starves the algae that remained after the blackout. But the plants are fine and ready to photosynthesise. At least that is how it's supposed to work according to your previous advice, and that is what I have seen - good results doing what you suggested it. --Nikolay |
