Thanks! you should join the rewarding and affordable hobby of keeping planted fish tanks, then. there is a wealth of knowledge on the internet and on youtube about setting up planted fish tanks. it can be frustrating at first, but as one gains experience and knowledge, it will get easier.
as for the size of my tanks, they’re 20 gallon long tanks (~30”x12”x12”). it’s the biggest tank i could carry on my own and fit in my room. lol! so, they’re not nearly big enough for the ecosystem in the tank to take care of itself. but, there is still a mini ecosystem of sorts going on in that the live plants help clean and oxygenate the water and the fish/shrimp waste help feed the plants. but, as mentioned, since the tank only holds so much water, there has to be a balancing act between excess nutrients from the food and fish waste and how much the plants can take in. so, if it’s out of balance, there is an algae bloom or if it’s really really bad, ammonia and nitrates can build up, which can kill fish. this is where i come in. to balance this, i do a 25-35% partial water change every week. the partial water change, to me, keeps the balance in order. the other things i do, like clean the glass if there is algae, or clean the filters, or trim plants or whatnot are things that i do when there is time to do them. so, they might get done every other week. but, every week, i do the partial water change or i fear that the “system” might go out of whack. lol! plus, it’s fun doing them.
i haven’t kept fish tanks for that long, so i don’t know how long one can keep a tank without water changes. but, i have heard of the “diane walstad method” where the tank is semi-self sustaining in that it can go without water changes for months.
here is a wikipedia link:
thanks again. you should try it!
