I have started cycling my 8 gallon tank without any fishes. It runs a power filter and an undergravel filter. I'm feeding the tank twice a day. I'm a bit confused with what fishes I can add to the 8 gallon
I know test strips are generally not recommended because they're not as accurate and reliable as liquid tests are, but liquid tests are usually more expensive from strip tests. I suppose, if you can't afford the liquid tests, strip tests would be better than none at all. But, yes, you need some kind of tests to know the progress of the cycle.
For an 8 gallon tank, why not go back with a mix of Mollies and Swordtails(two females and one male of each) for the potential mix of colors in the fry, plus they're both a pretty hardy species.. another thing to consider is the source of water and treatment methods used by the LFS you buy your fish from, if your LFS uses water from the same source(reservoir) you do at home, then why not ask how they treat the water they use in the tanks their fish are in and apply the same for your tank at home.. as far as how much longer you should continue your fish-less cycle, I'd say another 10-11 days should do it.. bear in mind Lokky, there are books written by fish experts like Dick Mills, Neal Pronek and Dr. Gwynne Vevers that downplay the need to cycle tanks and place more importance on water-quality/treatment and the optimum numbers of fish according to the size of the tank, along with a proper feeding and cleaning/water change schedule. In the next several days, you could be back with a tank of fish, just be sure to shop for healthy ones because no matter what your tankwater readings are, you'll face an uphill battle getting them healthy again and preventing the others from getting sick.. make sure there are no signs of finrot or ulcers to the body, also look for erect dorsal fins which according to the experts is a sign of good health.
I don't know on a small tank, maybe it is faster, but in the forums I've read people seem to have to wait at least 3 or 4 weeks until their tanks are cycled. Maybe someone on the betta board with a smaller tank knows? If you do put fish in now, do tons of water changes or you may lose them. Waiting is hard..isn't it!? good luck!!
I'll be in no hurry to add fishes, as I have already gone through a gruesome period over the last four months with an uncycled and overstocked tank.
I'll be humane this time. I have gone through a post saying that a few non-attractive, but happy fish is better than a lot of unhappy fish, which are so beautiful.
I'm researching the internet for information on various species. I'll probably end up with one of the livebearers or a betta.
Meanwhile, I feel that the power filter i have added is a little too fast for my tank. It pushes the food that I feed the tank so very fast, that I'm a bit sceptic about how this strong current will affect the fishes. Any comments?
what i done was waited a week cycling the tank and went to my local shop and bougt some guppys. guppys are able to survive almost anything are look great.You must be prepared to have loads of baby fish but if you don't want them thwn let nature take its place.
Thanks fr the comments Timesdragonfly and mcminnj.
Timesdragonfly, the filter doesn't really have a knob to control the flow of water.. I have attached the picture of the filter i got from one of the sites.. it is exactly the same brand and make.. i have for my tank.
mcminnj, i don't really want to strain the small creatures.. with all the ammonia and nitrite stuff..
I was so fed up the last time, i saw my pets going off one by one.. So, I decided to be patient this time..
Edit: The one inside the red rectangle is the one I have
It appears you have a canister filter. You should have a valve on both the inlet and outlet of the filter. If there arent valves, you should get at least one. splice it in line on the hose. Use a couple hose clamps tokeep it from leaking.
I do not really know of any easy way to lower to pressure other then to get a smaller filter. I personally think that 10 times the tank size filter calculation is to much. As long as there is good water circulation, no dead spots in the water and the tank is not over stocked, 2-3 times the capacity is just fine. In your tank size if it were mine i would get a filter for in the 20-30gph range, and it should be just fine.
