i got the lev from charles at inmkr and finally got the correct dose, im currently taking 90% of the water out of the tank right now and already have the lev mixed up, its just a pain to vac my 20 gall cuz its sooo fricken planted and i dont wanna hurt the plants. I dosed my betta tank already since i vaced that a day ago but im not sure they have it but im doing it as a precaution! I really wanna dose my fry tank but i dont know how i would dose a 1 gallon tank and i just sucked it up and put the new fry in with the old fry but i took extra precaution not to get ANY of their water into the fry tank since they were coming from the 20 gallon. They 1 gallon is just temp untill i can get enough cash to get a filter since these worms used up alot of my money!! I did read your thread jannika, like all 15 pages of it. Another member refered me to it, kaosku did and it seems like you guys went through hell as well!! I have been hearing that fenben works in water or only works in food and not the water, just wish i knew the truth about it! The lev is nice tho since it is clear!! Well back to vaccuuming my tank!! I hope the shock from all this doesnt kill any of my fish and it really sucks that my tank just got cycled 2 weeks ago, im sure its back to day one now!! Just hope the bio-wheel works like it says!!
