Foam too...

1. 55 Gallons.
2. Freshwater.
3. Setup for about 5 months.
4. 2 Goldfish, 1 Pleco, and 1 eel type fish.
5. I do have live plants.
6. About 72 degrees.
7. Bio wheel 350.
8. No Co2.
9. I do have natural sunlight.
10. Changed about 20% yesterday.
11. Weekly water changes.
12. Goldfish flakes once a day and sometimes brine worms in the afternoon.
13. 2 flourescent bulbs for about 12 hours a day.
14. I did a water change yesterday, today I woke up and the water looks very cloudy...almost foggy. Water was very clear yesterday after I changed it.
15. I frogot to record the water parameters but they are all normal, pH was a little low.
16. Liquid test kit.
17. I bought a goldfish like a month ago, he stayed in quarentine for about a week and is doing great.


I woke up today to find some kind of white foam floating on top of the water...this day 2 after the cleaning and the water is still foggy as well. Any idea? The fish dont seem to mind it, they look great still.

How often do you replace the filter media, it should remain undisturbed for at least a month and you have a filter that is rated for up to 75g on a 55g so it could probably be left longer as long as the water flow is good. I never change the water every week. My tanks are lucky if they get once a month and that's only if nitrates are high. It sounds like a bacteria cloud from changing the water, if it's white cloudy. If it's greenish then the natural sunlight could be a factor in causing algae. How much Natural sunlight does it get daily? And is it in a direct massive sunlight gathering area? Goldfish love to poop a lot and cloud water, although your filter sounds like it's adequate but a canister wouldn't' hurt. Try not changing the water every week and keep it 25-45% once a month. Try to limit any sunlight. Also are you adding any supplements?

O yea and lol what are "brine worms"?

Oops...I frogot, its blood worms! I live in Japan and the locals dont know the words for things so they are sold as "brine worms" but they are blood worms...I guess they are rubbing off on me. My tank is about 4 feet from the window, but the sun is very intense here in Okinawa, maybe I will try and close the window shades tomorrow. I dont add anything to the water as far as supplements and I have never touched the filters. I'm gonna try some small water changes to see if it helps. We will see!

this white foam on top of the water is fairly common, i think its partly caused by bactiera, when you touch the top of the water does the white foam disapate quickly? then return when the water is undisturbed?

the easiest thing you can try is if your useing a HOB filter lower your water level an inch or 2, this will in turn cause the foam to be mixed off the top of the water into the rest of the water where it can be cleaned by your filter media.
