NanotankBank Posted December 24, 2022 Share Posted December 24, 2022 Hello all, Ive recently found interest in keeping no filter, no water change, ecosystem tanks. I have a 3 gal Aquarium bowl sitting around that I wanted to make into a shrimp tank that requires minimal maintenance. I am new to the whole “little maintenance” world and I am asking for all pointers. Plants, substrate (how much),media that I can put underneath the soil, etc. Thank you! 1 Link to comment Share on other sites More sharing options...
Patrick_G Posted December 24, 2022 Share Posted December 24, 2022 I love little no filter, invert only tanks. I’ve set up three and I currently still have two. They’re really easy, I use aquasoil as substrate and decent low budget clip on lights. Plants seem to grow well and I don’t have any real algae issues. Here’s one from about 18 months ago 3 2 Link to comment Share on other sites More sharing options...
BigJ Posted December 24, 2022 Share Posted December 24, 2022 My scrapes from scraps was basically a scaled down version of what you are describing. Here is my most recent picture, I can't get a new one because I just tore it down to setup my new 20 long. It's final state was basically the same as this photo just more of everything, more peace lily, alge, anubius, and shrimp. As for maintenence I just did topoffs every several weeks and that's it. If I would have put just a little more time into maintenence it could have been pretty nice. But it was no tech super low maintenence and enough of an ecosystem for my shrimp to breed. Build details are in the linked post and somewhere there is a "reunion" thred with updates. 1 1 Link to comment Share on other sites More sharing options...

It was it strictly 0 tech whatsoever? 1 Link to comment Share on other sites More sharing options...

It was it strictly 0 tech I’ve been stocking these little tanks with mostly just snails, but I did have a little colony of mutt shrimp and some Sparkling Gourami going in one of them with only a heater. In that tank I ran a small sponge filter with an airstone until the plants grew in, after that it was just the heater. Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted December 24, 2022 Share Posted December 24, 2022 (edited) Here’s my little 6 gallon Walstad cube. Crazy jungle After a trim. Just a heater and a light. Dirted substrate capped with gravel. No filter, no fertilizer, no air pump, and a 20% water change every week. This tank pearls more than tanks I have with c02. Shrimp, snails, and a couple CPD’s. Just over a year old at this point. Edited December 24, 2022 by AllFishNoBrakes 4 Link to comment Share on other sites More sharing options...

I find that shrimp did well in water around 70-74°F, but every heater I find sets it between 78-80°F. Also, when doing water changes, do you do any form of gravel vacuuming, or just simply change the water? Link to comment Share on other sites More sharing options...
AllFishNoBrakes Posted December 24, 2022 Share Posted December 24, 2022 (edited) @NanotankBank Ya, I believe the heater is necessary in this one for the CPD’s and because it’s by a window. In my actual shrimp only tank there is no heater in there. If you’re doing shrimp only I would say no heater is just fine. No gravel vac, just water change.

Okay perfect, yes it will be shrimp only, may throw in a snail or two because they breed like crazy in my community tank. Thanks! 1 Link to comment Share on other sites More sharing options...
