Ick and fin rot.
Should I do a partial water change between the ick treatment and using the Maracyn?

You need not use antibiotics to deal with finrot as finrot is a minor setback possibly to water quality most of the time. What ich treatment do you use? Use salt at 0.3% solution (3 teaspoons per gallon) and increase heat to as high as 84 degrees Fahrenheit. Remember to dissolve the salt thoroughly and add slowly to avoid osmotic shock. If you are to perform water changes, redose the salt per the water volume replaced.

I am thinking the problem could be trying to keep livebearers in soft water. Some time ago another member suggested adding crushed coral to your filter area to raise the 6.6 ph you posted to a more alkaline 7.4. Live bearers,, such as mollys and platys simply don't do well in water with ph values less than 7.4 in the long term and finrot,fungus,and possible ICH could all be related to improper water conditions for the fish to thrive in. A cup ,or perhaps a half cup of coral chips, found at fish stores and often sold as saltwater substrate will increase the alkalinity to a more favorable degree for the fish you are keeping. And I also agree with another member who suggested using water from outside spigot, or faucet, IF your water that you use in the aquarium is going through any kind of water softener.
As Lupin said,finrot,and fungus are often signs of unfavorable water conditions and until water conditions are improved,,the fish will continue to be affected and medications will have little effect.
There is a cheap formula for hardening the water that is used by some for keeping fish who need alkaline water and perhaps it might interest you.

One Teaspoon baking soda( Sodium Bicarbonate)
One Tablespoon Epsom salt (magnesium sulfate)
One teaspoon marine salt (sodium chloride and trace minerals)
This formula is per ten gal of water. Best to mix it in rubbermaid tub and circulate the water for an hour or two. Then check the pH and if it is suitable, not too alkaline (hard) then slowly add this water over the course of a week with small water changes every couple days.
If none of this appeals to you,, then I suggest keeping fish that appreciate the soft acidic conditions that you posted in earlier thread.
Assuming (always a bad thing) that your water test zero for ammonia and nitrites ,and nitrAtes are kept at low levels through weekly water changes of 25 percent ,,it is the acidic conditions (low pH) that is contributing to the problems you are having.

Lupin, What kind of salt are you referring to? I was told over and oer agin, in the past, not to use aquarium salt. Are you referring more to what 1077 is talking about or ..?

Oh and I am using quick cure for the ick. I also have pleco's and tetras in the tank. Is harder what goig to hurt them? Beisides the ick and fin problems with the live bearers, the Plecos tail literaly shreaded and disappeared in a matter of a few days. I have tested my tap water (no water softener involved) and it is a pretty reliable 7.0, yet the tanks always seem to be slightly lower. Could a water condition (Aqua Safe by Tetra Aqua) used to "remove chlorine, chloramines and other heavy metals" put into the tap water, prior to being added to the tank, cause the ph level to drop into the sixes? Because that is the only other thing I can think of. I realize 7.0 is the bare minimum for live bearers. I'm just trying to figure out why it drops from 7 to 6 something.

p.s., I am thinkig along the lines of what 1077 said. But I was also wondering what kind of salt you were referring to.

Any and all help is appreciated.

Is this acceptable for the filter?

Florida crushed coral substrate?

Twistersmom 10-21-2009 07:35 PM

Lupin is referring to table salt. I use the same treatment for curing ick.
With, you already having quick cure in the tank, the heat/salt treatment would be too much. Heat depreciates oxygen levels, as well as meds, so I would only do one or the other.
I will leave the advice on raising ph levels, to someone else. I have no first hand experience with it.

Thank you, Twistersmom.

I just got over ich a few weeks ago. I raised the temperature to 82 degrees and used quick cure. Be sure to use and kind of medication for ich at least 48 hours after the last visible sign on the fish. I did water changes every other day and vacuumed the gravel to help clear up the ich that had fallen off the fish to the bottom of the tank. I used the medication at half strength because I have some scalefish fish (tetras) in my tank. I am happy to report I had no fatalities and all my fish are happy and healthy again.
