– Arapaima fish in Aquariums is wrong if the tank is too small. What if the tank is huge though? If your keeping monster size fish, get yourself a good filter. Here is a link:

More talk about fish tanks:
I mentioned dechlorinator as there have been people who have spent a month, sometimes two months cycling their tank and failing as they didn’t dechlorinate their water as they assumed since no fish are being added, it isn’t needed. Seems silly, but it is a common mistake.
Pure ammonia would be best, if you can find it as you have bacteria in that tank, probably starving right now. Yes you can add fish food and as it rots, it will release ammonia. I really wouldn’t know. I have never needed it. Have a tank for 20 years, so never had to cycle.
More importantly, you don’t have to cycle your new tank. When you do set it up and pick up a few fishes, move 50% of your seeded media to the new tanks filter and move the 50% unseeded media from this new filter to your old seeded filter.
Also squeeze the gunk from one of the sponges of the cycled filter into the new filter and add whatever bacteria in a bottle you have and you have a cycled filter. Just don’t overstock the new tank right away and two large water changes a week to both the tanks, until both filters are back to max biological filtration capacity.
A good question. Constant “new” water would be ideal. As long as it is consistent and has nothing harmful in it. The term should probably be “cycled media”. It is called the nitrogen cycle and what you are really looking for is a balance between (ammonia, nitrite, and nitrate) and two beneficial bacteria (BB) that keep ammonia and nitrate converted into nitrate. And then you only have to remove nitrate. And there are different ways to do that.
From what I’ve collected in the short time that I’ve been in this hobby, if the water hasn’t been cycled it can still pose different dangers to the fish. An uncycled tank is just a recipe for disaster because there’s nothing in there to combat the incoming bioload.
No such thing as uncycled water. It’s the substrate in your filter that gets cycled. Adding water from a cycled tank to a new one or vise versa does nothing. The only thing to watch out for is ammonia levels in the water. If a tank is not cycled (does not have sufficient bacteria in the filter substrate) the water can contain ammonia and nitrite that is unable to be broken down by the filter with no bacteria. So if you had a tank uncycled with fish in it and you took that water out and put it into another new tank it would have ammonia in it. That makes no sense to do though. Fresh water does not uncycled a tank or anything well as long as there is no chlorine in the water atleast.
Even the term ‘cycling’ is wrong as it implies a circular thing. It’s more a matter of achieving a point of chemical and biological balance. All elements within the tank, including water, should ideally settle to a point were the fish can live. Ammonia is dealt with enough to remove it. Nitrite is dealt enough to remove it and Nitrate is dealt with enough so it doesn’t build up too much.
Water delivered to a tap is under pressure and contains dissolved gases, in particular, CO2. A significant amount of dissolved CO2 will temporarily lower the pH of the water. That’s why it’s important to let it sit for a few hours, or a day.
How often should you squeeze out your sponge filters? I do mine with every water change… Just squeeze out in some tank water. Don’t know if this is correct or not, but I don’t have a very big tank, so am conscious of keeping it well filtered. Squeeze in same water and do it as often you see some smooth layer/ brownish substance clogging been formed on surface of sponge.
Basically never. I give em a good squeezin when they get too much algae on the. And while I’m at it I trim the algae and squeeze em out in discarded tank water until no hunk comes out. I do ours 6 – 9+ months- depending on which tank it’s in. The 40B community tank with all the guppies gets it the most at about every 6 months if I notice the water flow slowing down.
Every couple of months… but sometimes it depends on how stocked my tanks are. Also depends on the how much media you have in your filter and what kind of filter…. canisters tend to have bio balls as well as sponges… where some filters only have sponges.
