OK sorry for my recent brevity. I was out at the stores on my cell. So here's what I did. I was at petsmart and the master test kit was $32.99. I didn't have that much and it seemed pricey. And there was no nitrite kit. I went to the local exotic fish store where the master kit was $36.99 and the nitrite kit was $11.99. I was like geez. Went outside and looked it up on amazon and bought it right then and there for 19.99 free 2 day shipping. So it will be here Tues or Wed. I figured I could use my old nitrite tester kit and see what happened for now. So I get home and I have the test solution but no card to compare it to. Great. So I did the test anyway and figured maybe I could describe the color. Well I found the card online and since my solution is a nice light blue I assume I have 0 parts per whatever. Yay! Granted its old solution with no exp. date on it. But that must be a good indicator...

To better describe my "major water changes"... About 4 weeks ago when I brought the frogs home. I did a quick vacuum, sucking out about 1/4 of the water or less. A week later I did the same thing. 1/4 of the tank. A week later I did what I would call the major water change, when I got the gravel out of there. I would say I replaced about 60% of the water, using stress coat with all the new water. In there somewhere I changed the filter cartridge which is one piece with carbon inside surrounded by floss. My bio wheel spins like crazy after I change that. I thought I had to change it to get the carbon in there. Lesson learned. Certainly cheaper to wash it in old water and put it back in. But it will get gummed up at some point and have to be replaced I assume. I have a pretty good growth of brownish "stringy" algae that hangs out of the tubes where the water comes out of the filter and assume it is all inside there as well. I thought the bio wheel was supposed to be the thing that kept the good bacteria and whatnot...

So it seems my nitrites and ammonia levels are really good. Al never ate well right out of the chute, not like Norm, so I wonder if there was something wrong with him to start with? I am going to google pics of red leg and see what that looks like. It seems odd this was on one leg but I really dont know anything about it.

Thank you so much for your help!
