I do 20% water changes once every other week, my tank is pretty heavily stocked but I have an overflow system that I've modified to being very efficient at keeping the tank clean, I also have a lot of loaches that churn up the sand. I just remove the poop that I can before it starts to foul up the water and stuffMalaysian trumpet snails take care of all of the waste and turn the gravel for me I do weekly 50% water changes
I have tested and they aren't overly high, about 30 ppmUnless you are crazy packed with plants and probably even then I would imagine your nitrates are high enough to affect your fish.
I have tested and they aren't overly high, about 30 ppm
it's a biocube 29, I have 13 kuhli loaches, 3 dojo loaches, a green phantom and gold nugget pleco, 1 betta, 3 red eyed tetras, 1 albino red tail shark and 2 albino cherry barbs. I do a 5 gallon water change every other week, but when I see waste and stuff accumulate I siphon it out through a coffee filter. I have an overflow that has bioballs and a bunch of sponges that I put into it to increase surface area (also to prevent my kuhli loaches from going into the sump for the heater/protein skimmer). When I do the water changes I remove the sponges and rinse them in some tank water to remove waste. I also have duckweed, a banana plant and some cardinal plants in there. I feed one cube of frozen food every other day with a pinch of crushed freeze dried krill and 2 slices of repashy morning wood for my plecos (I pour it into a container and let it settle, then I use a potato peeler and slice off a piece to give my plecos).20% water changes every other week? And you have a heavily stocked tank? And your nitrates are 30ppm? I'm intrigued. Can you give us full details of your set up, tank size, filtration, stock etc etc.

Well my parents hate me doing water changes because "it costs so much money", I'm lucky in that the flow makes the waste accumulate in one areaI think the key to your success then lies in the fact that you syphon out gunk as it appears, that factor alone will help keep your nitrates low. Most gunk in most people's tanks (myself included) gets sucked into the filtration system and remains there to decompose until maintainance time.
