Algea bloom, I think

Badmans Tropical Fish Message Center: General message area: Algea bloom, I think


Thursday, February 28, 2002 - 07:45 pm
Hello, first time on the message board. i am having trouble with what I think is an algae bloom. I have changed my tank to African cichlids and added some rocks to the setup. I am now troubled with clouded green tinted water for about two weeks now. I do water changes every week & feed once a day. All test levels are in check. I have been a fish owner for a long time and have never had this problem. I also have more than enough filtration, does anyone have any suggestions please.

Does your tank get direct sunlight? If so, move your tank to a location where it doesn't get any.

Some questions:
Do you have live plants?
Has your water supply changed in any way?
What kind of "rocks" did you add?
What light source are you using?
On the once a day feeding, how much are you giving?

Give us some clues and maybe we can tell you what caused it and how to fix it.

African cichlid tanks can have a few problems with algae since keeping plants in a African Rift Lake tank is very difficult due to high ph and the fact that the fish dig up and eat the plants. Some Lake Malawi fish tanks do use hippo plecs or syno catfish, however realize that if you add a catfish they may consume any fry. Best bet is to check your light levels. Some mbuna are also vegetarian so they may possibly help control some of the algae. Also how many fish and what size tank? What filtration are you using? Stocking levels can be high in these tanks adding to excess waste and algae problems.

Saw your other posts and 10 fish in a fairly new tank could be adding to your problems. I have my 75 gallon Lake M tank in the basement on an auto timer with only about 5-6 hours of light. I do have a little brown algae on the tufa rock, but the fish like to pick at it. I am running an Eheim 2026 and a Magnum 250 HOB. I currently have 14 fish in the 75 gallon which has been set up since November 2001.

I appreciate the help. I don't have any algae just green water. The tank is 3 months old but recently changed over to African cichlids. I don't have any live plants. There is no sunlight near the aquarium and only feed once a day just what they will eat within 2 minutes. The water supply is still the same. The rocks are petrified wood and lace. I am running two Whisper 3's and an Heim 2235 Ecco canister filter. The light is flourescent and it is on about 8 hours a day. I have been fish crazy for a long time and I have never had this problem. I expected a little cloudiness from the new rocks but everything else is reused even the water on my initial changeover. I got the cloudy water and they a few days later it started turning to a green tint. I appreciate any help. sorry so windy.

I recently set up a 29 gallon tank and had the same problem for 4 weeks. Water changes wouldn't help at all. i finally got relief from a product called Algae Fix made by Aquarium Pharmaceuticals. No lie - it cleared the entire tank in less than 45 minutes. I could actually see the water color changing before my eyes! 6 weeks later, my 4 danios and 2 tiger barbs are enjoying one of my clearest set ups yet. By the way, the green water didn't seem to harm the fish at all - I just couldn't see them!

Thanx Chris Your problem sounds like mine. Water Changes don't help my situation either. I hate to resort to chemicals but nothing else seems to help.

Well... If you dont' want to resort to chemicals, you can try any of the methods below.

1) completely cover the tank for 3 days so that NO LIGHT penetrates. This chokes out the algae

2) let the cycling process ride out. after ammonia, nitrite have levelled off, wait for it to clear.

3) if it doesn't clear after cycling, change 25 percent of the water twice a day.

Method 3 worked for me. It was a last resort but it worked after two weeks without the use of harsh chemicals. These algaecides can wreak havok on aquatic systems if they get in the wild.

Good luck!

Thank you lboy, I am going to try this first. I covered the aquarium for 1 day already. Your idea sounds good.



Saturday, March 02, 2002 - 09:07 am
I trief the covering of the tank for four days, and the water just wouldn't clear up. I started with 25% changes every other day, went to 50% and then after 3 or 4 weeks, tried about a 95% water change. It seems every time, after two days, I would see the green get thicker and thicker no matter what I did. I really didn't want to ad chemicals in to my setup either, however I exhausted every other option. I hope yours works out for you without adding anything in, but as a last resort, it should work for you. Good luck!

Wow, sounds like quite the season for algae lately. Mark, I think you posted as Anonymous on the other side of the forum, and I answered some of your questions there? Other than that, just wanted to say a few other things...

The green water is just suspended algae, it's not really anything more mysterious than the anchored algae, though there are many species that make up both forms. And you are right, they will not harm your fish directly, but does make viewing them a pain. I also recommended water changes and patience rather than algacides, but can understand your frustration at the slowness of the process. But one other option I omitted to mention that might help both of you is checking your phosphate levels... high P in the water, especially in a relatively new tank will notoriously spawn algal blooms. You can purchase a phosphate sponge (that you can cut and insert into your filter) that may help. Other than that, all I can say is reduce light, have faith in water changes, and have patience; algae never goes away completely but the blooms usually reduce on their own as the tank ages.



Saturday, March 02, 2002 - 10:45 am
Thanx Chris. I am so far going down the same road it sounds like you have already traveled. I have already done a 50% water change and if the cover doesn't work or change anything within the next day or so I am definately trying your idea. So far like you, the cover and water changes aren't working. I am going to get the algea clear today. I appreciate the help because your situation sounds exactly like mine.



Saturday, March 02, 2002 - 10:42 pm
Thanx again Pandora, your right I am on the other side. I am new to the message board and did'nt know where to start or how. I think I made enough mistakes, duplicate messages etc. I am sorry but I think I got my act together. I was really conserned about my aquarium and needed everybody's help. It is nice to find a site that cares as much for fish as I do. The help has been great and I have learned from this help. To everyone thank you and I will stay in touch.



Saturday, March 09, 2002 - 09:22 pm
Have any luck???



Tuesday, March 12, 2002 - 07:37 pm
Thanx for asking Chris. The lights off worked. No more algea bloom and my water is back to crystal clear. The Africans are doing great. Now I have bacterial infections from the fish fighting but I can cure that easily. I appreciate every ones help.

OK, I have a problem...when I turn of my lights for an extended period of time, I come home to green water. I don't understand it, because you just said to turn off the lights, ad it will choke them out. Now, when I turn the lights back on, the water is really green, but if I leave the lights on, it will clear up, sort of. I have algae all over my gravel. I might just start over when I have some extra time.



Wednesday, March 20, 2002 - 05:51 pm
Pandora's advise for the green water usually works and it's also the same as what I've read in magazines. I don't know why you are noticing more with the lights out. Algae needs nutrients and light to propagate. If you vacumn it off your gravel at the water change may help some. If it's a new tank it may just take time to go away. Make sure you aren't feeding too much and that the tank isn't getting too much light from the windows.

ok, bad news....for some strange reason I lost one of my fish! I think I may have accidently killed it when I was trying to clean the tank. I can't find the thing anywhere, so now I have only threee bottom feeders in my ten gallon tank. I just went ahead and started over, since the gravel was so ucky. I have bottom feeder pellets. How many should I feed them? I know they have to consume them in two minutes, so should I really skimp on them? I'm thinking that's what I may have to do. Right now everything is apart, and the tank is now full again, with clean gravel, clean water. My gravel was nasty. I don't see how the fish survived without getting sick. There was food particles all thoughout the gravel. So now I'm going to do everything I can to limit feedings. Did you all say it was only nessessary to feed them every two days when I first do this?
i'm using a dechlorinator called PRIME, and that's supposed to take care of nitrites too!
I'm making a new-tank resolution that I'm not going to use it as a nightlite. I did have a tendency to do this. The fish I have are Cory cats. They are very hardy fish. Well, I'm done ranting. I'll be back from time to time!



Thursday, March 21, 2002 - 09:45 am
Michelle you might want to read Genesis on Pat's main page. By redoing your tank the cycling process will probably start over. I would really watch the ammonia levels. What kind of filtration did you use? If you used a UGF and in fact cleaned the gravel you also removed the good bacteria. I have two peppered cory cats that are over five years old. They basically exist on scraps of flakes from the others. I usually add an algae wafer once or twice a week. If you have algae and excess flake in the tank you certainly don't have to throw in something else. These fish can survive on only a tiny amount of food. If you are lazy about the tank light suggest a light timer which you can get for 4 or 5 bucks at a hardware store. This way you don't have to worry about forgeting to turn out the light.



Thursday, March 21, 2002 - 10:58 am
Michelle, Ditto on the cycling concern. You also might consider putting some plants in the tank. Depending on your lighting you can find something that will work for you. The plants will compete with the algea for nutrients and, hopefully, the plants will win. Also the plants improve the water quality by using up some of those excess nutrients and ammonia. It will make the cycling easier on your fish,and my coreys love them.
