How to maintain an Aquarium without a filter ?
I have 2 bala sharks and 2 dalmation mollies in my 16 gallon (60 liter) aquarium tank.How to maintain the tank without a filter for best results and for longer life span of the fishes.I cannot afford the filters , so kindly guide me.
Sorry, since you have posted your question twice (with ‘fish tank’ substituted for ‘aquarium’) I am going to be lazy and paste my answer to your other question here:-
You could never do enough water changes while keeping the fish healthy and keeping up with the ammonia/nitrite/nitrate levels in the water. One of the main sources of beneficial bacteria that ‘processes’ the toxic chemicals ammonia/nitrite lives in filter media. You will quite possibly have to spend more on replacing your fish (not to mention the pain and suffering you put them through in the process) than it will cost to get a filter for your tank. Filters range from $10 for underground filter and around $30 for a power/hang-on/over-flow filter. The Tetra Whisper 2 should be suitable for your size tank.
On the other hand, your bala sharks may cost from $2.50 to $7.50 each depending on size and location of the store. Your dalmations will cost from $2.50 to $5.00. Of course I don’t know where you got your fish from or how big they are but how much can you replace them for? Even a box filter is only around $5.00.
Ideally you need at least a 50-55g tank for your balas, 75g depending on their size, so without a filter they may already be suffering. If you can’t afford a filter it worries me that you won’t be able to afford a bigger tank for your balas, so I’m so sorry to say you really need to consider rehoming them for now….
If your fish die, you will have the added expense of not only replacing your fish but also giving in to buying a filter to avoid the same potential disaster all over.
I hope that was gentle enough, maybe you could scratch the money up from somewhere??? (IDK, cut down on fast food, sodas, and whatever other treats you have while your fish are suffering :(() … $5.00 is not that much 
Good luck

The Bala Sharks can grow to be over 1′, your tank is not bis enough for them. Otherwise, do a 25% water change, with a gravel siphon every 2-3 days. You really would benefit from a filter. Do you have a heater? All of your fish require water temps of 75-80. Join your local freecycle.org, and ask for 1, or put a wanted ad on your local craigslist.
