Re: canister filter diy???
That's not a canister filter though, it's an internal filter.
I addressed this issue in my first post.
yes, because since what you put together doesn't have any silicone seals that can leak or move water in and out of the tank. not to belittle the utility and simplicity of what what you built. imo building a tiny canister filter for a small guppy tank is like building a tiny jet engine for a moped instead of building a moped engine out of moped parts already laying around.
It's not actually a canister though, plus... Ammonia and nitrites stay at zero, nitrates at around 40 without water changes for over a month now.
