I have a emergency situation a couple of my fish have ich. I have been low on funds. So I bought microbe-lift herbtana. I have been using it for almost 2 weeks it sure is keeping my fish from getting too sick, im now got a 20 gallon tank and all the stuff to go with it just waiting on it to cycle. I'm still dosing my 75 every night, while shutting the skimmer down and using a air stone. I also have been feeding them 3 times a day. Keeping them as healthy as I can. I now have the hospital set up and running. I read that you could use water from your main tank. So I added 10 gallons from my 75 and 10 gallons of rodi salt water. I had some dr. Tims one and only in the fridge from my 75 set up. So I added the recommended dose and added ammonia chloride too 1ppm. Cranked the temp up to 84 and let it go. It's been 2 days my ammonia has dropped too .75ppm and no nitrite 0 ppm. I have a clean tank with just some pvc in it and the hob filter. The question is how long will this tank take to cycle or do I not even need to worry about cycling it since you have to change the water so much. I need to get my fish in this tank asap, of coursei know i gotta get the temp back down. Sorry for such a long thread. But I wanted to make sure I covered everything.
