Hi OFL. Again. Lol. My parents are already letting me buy the test kit. :D Anyway, does a bacterial bloom HAVE to happen once the bb start to grow? I never got one... And I've noticed that most members have a bloom, too. What do you think? ~LTB
Remember that the BB need-surface area, food source and oxygen to colonize-when one or more are limited this can limit the BB colony. By turning the filter off-this will stop the gas exchange and dissolved oxygen content of the water. Usually within 6h of limited oxygen the BB will start to die/suffocate-but since the tank was in the beginning stage of cycling what little BB may have been fine or not...hard to say.
Now that you can leave the filter on 24/7 its just a matter of time before you get the nitrogen cycle established.
Hi OFL. Again. Lol. Sorry if I keep bothering you but I have a question. A few days ago, I noticed my filter was too strong. I kept it off most of the time and turn it back on sometimes. And today, I bought a valve so I can control the current. I can now keep it on 24/7. :) My question is, was that enough time for BB to colonize just a little bit? I know the cycle takes weeks but I mean in that short amount of time, did BB grow? I'm just worried that when I turned it off the BB start to die off and when I turn it back again, it'll flow my tank with ammonia. If you can't understand my babbling, I'll try to make it more understandable. If you're not confused, please reply back. Sorry if it's confusing... ~LTB
That might be why you are having problems with them then....Low light, short photoperiod and old light bulbs. The overhead light in the room usually isn't enough-but the diatoms are harmless...just look kinda ugly....
OK, thanks. So they're called diatoms? I don't necessarily have a tank light. Lebron's tank is in my kitchen and the light is on around 10 hours a day. I'll turn it off and on it when necessary. Thanks for answering my questions. Is there another way to control the diatoms? ~LTB
You can remove all the water and be fine-but you don't want to vacuum too much, scrub the walls and change the filter media too...Just water only is fine since very little BB are in the water column itself. Rub the diatoms off and vacuum them off on a weekly basis and once the tank has matured they should resolve-unless your light bulb is over a 1 year old or you leave your lights on for 6h/day or less-that also can cause diatom or brown algae problems
