should i take a chance?

[jcf]

i am combining 2 twenty gallon tanks into one 55 gallon tank. from a previous question, i can add the water and gravel from one tank into the new tank to speed up the cycle.

my problem now is that one of the 20 gallon tanks has some type of disease consisting of small 1/8" worms that appear periodically. i know this is deadly because i accidentaly moved a fish into the infected aquarium and it died in one day. i have tried to kill this desease by using a dark blue chemical (i do not remember the name) as well as other parasite control tablets but cannot kill the disease.

should i take the chance of moving the fish into this tank to the 55 gallon tank without infected fish. In the event that i decide not to, can i move just the gravel?. if so, how would i steralize it? or should i just leave the diseased tank alone and go out and get new gravel?

this has got me really worried.

My advice is to take a water sample into your nearest aquarium and get it tested before you move anything. We lost our whole tropical setup because we stuffed around with diseased fishies. Even if it costs you a pretty penny its worth it in the end when you get the desired result from adding together 2 healthy tanks.

Hmmmm I doubt that it was a disease that killed your fish in the 20 gallon. one day is to short a time for just about any disease to kill a fish in.

What are the water values in the 20 gallon? have you checkec nitrate/nitrite and ammonia?
