Foamy Water

It is quite possible that this can be a foamy layer of broken down organic matter. In SW fish-keeping there is a peice of equipment just for this reason and it is called a protein skimmer. FW fish-keepers generally do not utilize such an item, but some tanks do need it, especially with the fish load that you are keeping.

I'm going to move this thread over to the General FW forum since this is not directly a beginner's question ! :)
 
Same problem...

Yo! I've got a 29 gal that has 2 firemouths and a pleco. At the most, I feed them like 5 to 10 flakes a day and they pick at the bottom for the rest of the time. I did a 30% water change a few days ago and the tank edge still has a small amount of foam to it??What would be a recommended daily or bi-daily water change?? I did put some melafix in the tank the other day because oneof the firemouths has a white pimplish thing underneath his right-side fin. I turned up the heater to 79 d. F. and it has been getting smaller; thinking it could have been a fish lice. Other than the small white pimple, he has been active and eating and being "mister trouble maker" with the other firemouth. Btw, is there a way to tell the difference between a male and a female firemouth when they are about one to one and a half inch in size?? Thanks!!

silvershark: 10 or 20% daily or bi-daily wouldn't be bad to remove various pollutants especially after treating a tank as noted. melafix will cause the bubbles......

for anyone that wants to hop on the wagon and say this is too much, i must remind you that fish live in an environment normally where the water change percentages run into the hundreds of percents. in a fast flowing stream you could get a 100% water change in 5 minutes, in a pond or lake you have a much greater dilution area for toxins and still have massive amounts of new water..........

the only cautions to doing this is 1) if you haven't been doing many changes up until now, you need to know your tank water and tap water is pretty close to avoid ph or other shock. 2) the temperature of the new water needs to be somewhat close. 3) use dechlorinator of course...... other than that i can't think of anything else. ALL fish benefit from fresh clean water, or at least all the ones i know of...........
