alge build up
 
I recently got rid of a common pleco due to only having a 29 gallon tank and knowing it would get to big. I went out and bought a rubberlip pleco and now my tank is starting to turn really green. I never had this problem with the common pleco, he was really good at keeping my tank clean all the time. Is there anything that I can do, or can I add another rubberlip to help him out? Im thinking about trying snails again, I got rid of the trouble maker that picked on the last snails I had in the tank

Something has to cause the algae, the solution is resolving whatever is out of balance. Can you give us more info on your tank: is there a tank light, what kind and wattage, and how long is it on daily; are there any live plants, and if yes, how many? And what is the algae? Here's a link to info with photos to help you decide: PG: Algae - An Overview - PlantGeek.net

Yes there is a light, not sure what kind or wattage and what not. It came with the tank and doesnt say on the housing. Its in a power compact housing if that helps. It has two bulbs inside but only one works. Its also has a "moon light" that is on when the regular light is not. The light is on12-14 hours a day. I get up at 10ish and turn it on and it goes off at 2am when i go to bed.


No I have no live plants, cichlid tank. Looking at that site Im not really sure what kind of algae, it comes off really easy, but kinda looks like that spot algae.

Didnt have any problems with algae with my common pleaco.

As a starter, you may want to reduce # of hours a day. Do you have a nitrate test kit? How much water do you change and how often?

Where are those algaes found?

Well from reading those posts sounds like I need to work on my nitrates. I have noticed they were a little higher then normal when I last tested.

I usually change about 20-30 percent water ever 2 weeks

in my tank i do a 25% change every week,....some one may rec doing daily PWC untill values are back to normal (dont do it untill someone with more exp. then me reccomeds) if you dont mind could you post your last couple readings and when they were done??? unfortunatly plecos arent the BEST algea eaters...mine usually plasters himself to one of my plants or vegitable i have put in there he rarely is on the glass. i know there are some other fish that are primarly algea eaters like the ottos but they thrive on a mostly algea diet so one the algea is gone they will slowly starve...they do not acclimate well to a supplimented diet from what i understand

Nitrates aren't causing the algae and they never will.

Does the tank contain plants?

This is quite straightforward. You have light plus nutrients, and with no live plants, algae will appear and use the nutrients in the presence of the light and multiply. Your pleco appears to have been keeping it under control. All sounds perfectly normal and natural.

A good algae fish that will survive with your cichlids would probably handle things, one of the small plecos. Also, reducing the light significantly would help; without plants the only reason for a light is for you to observe the fish, as fish don't need light per say. I would also eliminate the moon light at night. Fish (and plants if you had them) need a period of total darkness. Ten hours is suggested.

And a comment on partial water changes, as noted in subsequent posts, these should be every week, with 40-50% changed. As someone mentioned, nitrates themselves do not cause algae, but they are indicative of what does--nutrients. A weekly pwc will help handle this by reducing nitrates which means reducing some of the nutrients the algae needs. It is also healthier for the fish. There is an excellent article on this in the November issue of TFH. The toxins that rapidly accumulate in an aquarium, especially with larger fish, cannot be removed by any filter, only a pwc can do this. A significant weekly pwc is the best thing an aquarist can do for any aquarium without plants.
