Just Wondering

i was wondering if i could put two tanks together, not glue them together but run the same water through then so that the ammonia content would be more dilute. pretty much turning a 20g into a 40g but the fish would only have the same space to move in. so would it have any advantages? unsure.gif

hmm. I can see the logic, but i'm not sure how worthwhile it is. It'd be more expensive to heat, and I'm guessing it might just become a home for algae. I don't see a reason not to try it, and it could halve your ammonia (predictably!) but I probably wouldn't bother. There have got to be other ways to make the same improvments, and I can think of lots of better ideas of what to do with a lingering 20g tank!

if both tanks are stocked to the reccomended level then the net result is the same

20 fish in a 20 gallon would be the same as 40 fish in a 40 gallon.

save yourself the hassle. the benefits are likely to be slim to none

Nope, there should be NO ammonia in any tank. There should also be no nitrites. You must mean nitrates(note the 'a' instead of 'i'), but even then it's still not really worth the bother.
Buy a 'master' test kit, and get a filter rated for a tank bigger than the one you have got. Keep up your water changes. The booklets that come with these 'master' test kits will help greatly.
Basically no tank should have any ammonia or nitrites. Tanks will always have nitrates, but after the nitrates go over 40ppm it is potentially bad for the fish.
The bacteria in the filters get rid of ammonia and nitrite, and turns them into nitrates. You need to do water changes to get rid of the nitrates. In a bigger tank with the same amount of fish, there would be a lower concentration of nitrates, meaning technically you could do less frequent water changes. That is the only advantage, and its not worth it because water changes are necessary for other things .
In conclusion, don't bother.
But do bother buying a test kit .
