Need help with crazy green water!!! w/pics!
Penguin power filter
No special fish
light was on for 14 hours changed to 12
Here is the thing. Week ago I decided to change water and get some alge off the glass and at the same time take out my intank filter and connect penguin filter.
Did water change vacuumed the bottom and all 9 yards. On the second day after that I noticed that water was getting increasingly white (blurry)... I though well its just a bacteria going nuts. Another few days went by and all this white stuff turned in to green stuff... now all water is green. green like a green giant and started to smell little bit. Today I did a 35% water change and so far.. it cleared little bit but.. no significant progress.
I found this thread with a similar situation to yours.
I have not used Algone but a lot of people vouch for its use.
If you could add some crazy yellow water, you would have some crazy blue water.
Only kidding. You've got a problem, that's for sure. A few things that I would look at are: a) Feeding . How much are you feeding? Feeding too much produces food for algae. b) What kind of fish am you keeping? Some fish are living waste producers. This too produces food for algae to grow. c) How long are the lights on? Algae needs light to survive. 8-10 hours per day should be sufficient for your fish.
Changes in the above areas will definitely help. Another helpful hint would be to add plants like elodea or floating worts. These plants would compete with the algae for nutrients, thus controlling growth.
AlGone is a good product as are many others on the market. Just make srue to use any product you choose as directed. Water changes will be necessary as the dead algae will only perpetuate your problem or worse.
I, too, started to have a problem with green water although it wasn't as bad as yours. I started to notice that when I looked through my tank from the side it was cloudy. I also at first thought it was a bacterial bloom. But when I would do water changes the water was a light green. So I started only turning the lights on when I was home (for about 4-5 hrs a day), cut back my feeding from twice a day to once a day (only what they would eat in about 60 seconds). I also tried a product from Fluval called Clearmax (formerly Phos-X) that you put in your filter instead of carbon. It comes in pouches and reduces the phosphates in your water. Excess phosphates contribute to green water. Also lots of water changes. This really seemed to help. haven't tried the Algone although I will have to keep that in mind.
I have also heard for really stubborn cases of green water UV sterilizers work real well but that will cost more $$$.
How long has the tank been set up?
What are you water parameters? (ammonia, nitrites, nitrates)
How often do you feed your fish and how much?
What fish fo you keep?
How big is the tank?
How long do you keep your lights on for?
Few questions need to be answered. Almost seems like a combination of algal and bacteria bloom. Extra aeration, turning the lights off, small frequent water changes, and cutting back on feedings should help the problem.
One other thing, you said you were taking out the filter and replacing it with another? Was th e new filter already matured, or did you just swap an old one for a new one, cos you might have lost a bunch of bacteria and started a cycle all over again!
Yea, I had one of those filters that you place inside your tank and that a powered by air. it was all good before I changed it. but i had to change it because it didnt do a good job. so you think I killed too much bacteria. I'll add some tonight. I have this thing called cycle that has life bacteria in it. lets see what happens.
No over feed thats for sure.
Well, if you have taken out the old filter and replaced it with a new one then you probably have lost a lot of bacteria, as it lives mostly in the sponges in the filters, and started your cycle over again. In future, the best way of changing filters is to let them both run simultaneously till the new one has had a chance to gain a good colony of the beneficial bacteria that keeps your tank healthy (a few weeks will do the job.) No worries though, what's done is done!
So you're gonna get some spikes in your ammonia, nitrate and nitrite as the bacterial population in your tank builds back up to a stable level, and it may be this that is causing the white cloudiness (bacterial bloom) and the subsequent green stuff (algae, feeding on the spikes and the light levels). I always get a white cloudiness in my tanks when i'm cycling them, but it does go away after a while, but i suspect your light levels are a bit high (as previously said 8-10 hours is fine) so it's led to an algae infestation!
Adding some cycle might well help, as it'll help get the cycle going faster, but you'll really need to keep an eye on your water condition and parameters, over the next few weeks and be prepared to do a few water changes as the levels go up, or your fish won't like it all!
Have you got another tank that has a matured filter in it that you could take some filter media from? Or a friend that could lend you some filter media from an established tank? Just don't take all of it, or they'll have the same problem you have! If you can do this, then move the media from one tank to the other (keeping it wet with tank water - don't let it dry out!) and put it in your filter if there is space inside, or just weigh it down nearby of not, and it'll help seed your tank with bacteria getting it re-cyled much faster. Some gravel or rocks from another tank will do the same job, but not quite as efficiently...
Check out this sticky for cycling info, it's a much better explanation than i can give! http://www.fishforum.com/viewtopic.php?t=3738
Keep us all posted and i'm sure there are folks who will be able to help you more than me! But i'd really recomend testing your water to see what state it is in! Hope that helps!
Thanks for all the help.
I know how nitrogen cycle works and all I just didnt think that all the green water could be caused by removing bacteria (old filter) out.
I have cut down on light. From 14 hours to 9 hours and will add more bacteria to the tank. At the same time that this is happening my water seems fine. Ph levels are ok 6.6 ph and amonia level seems in place. so for me it was really strange that this have happend. Usially when bacteria dies off or removed you get spikes in amonia but.. no didnt even move.
anyway thanks for the help all.
Yeah definitely turn that light way down and see if that helps. When I worked for a fish store, pretty much everyone who had green water problems solved it by lowering the ammount of time their lights are on. Also, make sure there is no direct sunlight getting to the tank.
Otherwise, if you can't fight the problem, just go with it. Install a strobe light and some lazer lights and create a mini underwater dance club.[/code]
