Glass Betta Fish Tank Starter Kits, 2 Gallon Fish Tank with Heater Filter and Light, Self-Cleaning Small Fish Tank.

You can adjust the flow rate on the filter
I use this as a quarantine/hospital tank, and have an army of ramshorn snails living in it. Light works well for growing low tech (no CO2) plants on 12 hr cycle. If you want it to house a betta, try to find the same thing in a larger volume. If you want to grow out fry, it’s a good size for that, but you might have to put a fine screen over the filter intake? This tank is fine for neocaridina shrimp (e.g. cherry shrimp) and/or snails, and/or growing up/out plants for your larger tanks. Or for growing plants only because they’re pretty (plus a few snails to control algae).Some tips:-Turn on the light when you want it to come on every day, then set timer (toggle between 6, 9, and 12hr (red), – I believe) and brightness level. If you touch nothing else, it will pop on at that brightness for the duration you set at that same time every 24 hrs. I.e., if you want the light to come on at 8am, you have to wait until 8am to turn it on, then it will be set after that. If you don’t set the timer, then it stays on until you turn it off. Use timer and dimmer features to control algae growth (less light intensity/duration = less algae).- With light cycle at 12hrs (medium bright, all colors on) my low tech (non CO2 requiring) plants do very well, and the ramshorn army prevents algae growth, except when they get too big to squeeze between filter and the wall of tank.- There is a slider on the pump (at the bottom of the filter column, on top of pump intake, facing front). I believe if you slide it to the left, you get more flow and to the right you get less… Maybe 5 positions/flow rates to choose from? Also, as biofilms/beneficial bacteria colonize your sponge filter, the flow rate will decrease. This is a fine indication of when you should pull out the sponge and squeeze it a few times in dechlorinated water (maybe some of the tank water you removed for your water change?), then put it back. No additional cleaning of filter is required once tank is cycled, and flow rate will be higher. Pour the dirty water from the sponge onto your favorite house plant. I’m considering cutting sponge in half or quarters (lengthwise) to keep the flow rate higher… Would have preferred larger pores in the sponge.- No charcoal filter is needed. Use activated charcoal filters only to remove meds from water. If you need to remove smells, it’s better to address the cause of smell instead (overfeeding? did somebody die (especially a snail!!) is the water stagnant/is there a biofilm on surface/do you need to aerate more? etc). A healthy aquarium doesn’t really have a smell.- If you’re keeping a betta (a bigger tank is more appropriate for them, but I’m being realistic, some of you will put a betta in this) please note: you can turn the flow rate down to maintain filtration without exhausting your fish in a high current. If your fish is “running” to stay in one place, you will exhaust him and he will become very stressed, more vulnerable to diseases/parasites, and possibly die much younger than he should. Just turn down the flow rate, and he’ll be much better off. Better too low than too high (and add an air stone if he spends too much of his time breathing at the surface). I say “him” because most casual hobbyists buy male bettas because they’re more colorful/pretty.- You might want to add an air stone, as an appropriate flow rate doesn’t oxygenate as well as I’d like. But YMMV.- The heater is set to 85 deg F but in my (cold) apartment, the actual temperature is closer to 77-78 deg F. Not sure what it will be in the summer; can’t adjust it.- Light on heater is obnoxiously BRIGHT. Had to turn it to face the wall.- Lid has a 1/2 inch gap above front edge of tank. Keep this in mind if you are housing escape artists or have cats who like to pet the fish. This also means you will have to top off the water level more frequently than if it had no gap.Overall, this is a fine tank at a good price. It arrived well packed. Please do some Googling (or chat up your local fish nerd at the fish store) before you buy this to ensure it’s appropriate for the type of aquatic flora/fauna you want to keep.

Great
I absolutely love the aquarium. Perfect size for a small fish. This is what I want it for .

Junk
Junk. Clouded up. Filter is small and barely worked. Waste of my money. Would love a refund

Beautiful, but Filter Broke Within 2 Months
Beautiful aquarium, but filter broke. Please use a quality filter. Instructions are hard to follow. Amazing, amazing product. So beautiful. Faulty filter.
