Is it possible to cycle a 2 gallon? I am considering buying the 4 pack of the marineland explorers from ebay... but am wondering if it is even possible to cycle them? I know it can be done with 2.5 gallons. Maybe 50% water changes once a week?
I see...it is a kit...kinda cute...and as long as you have oxygen source it should cycle.....IMO/E
You know you are cycled when you have 0ppm ammonia and nitrite an 5-10ppm nitrate for several days without a water change...
IMO/E-in the 6g and less tank regardless of filtration and cycle with one betta/shrimp/snail....twice weekly water changes of at least 50% with one of the water changes doing substrate vacuuming to prevent water quality issues and health/fin issues......and removing any uneaten food in between pwc in the un-planted tank.....in heavy planted active growing planted tanks...water changes IMO would be different.
