It's not only for oxygen, it's also to degas CO2. This way the pH will rise and bacteria work 10 times better. Really, you should try it at your tank. I can see when the hose from the airpump is disconnected just by looking at my tank!
Sorry, I don't understand.
How can you see the bacteria are working better just by looking at the tank?
25mmI was calculating, the overflow pipe diameter etc. I was wondering, about the return pipes. Each return pipe will get a return pump that pumps max 6000 LPH (1500 GPH). After losing some to head pressure etc. What would be the minimum/ideal pipe diameter for the return pipes?
And why is it ideal?25mm
But would it hurt if I take for example a 100mm pipe (I know, the outflow of the pump is smaller so will be the bottleneck). Would it be better or would it fire backwards?Because your pumps are rated at 1500gph.
If you want to use hard pluming then any elbows will reduce flow, try to find bends in preference to elbows.
Certain pumps will deal with pressure far more that others, really depends on power rating & impeller design.
No conclusive answer without far more information but 25mm is pretty standard for 1500gph flow rate.
Haha thnx for the heads up! I specially imported them at my lfs. 5 min in the tank the Hygrophila corymbosa (not generally a very eatable plant) was only a twig! So I already found out the hard wayDawkinsia rohani or puntius filamentosus or any other similar fish will plough through your plants
I like these, but I've never had a tank large enough to keep a good group of them. I think I've read somewhere that the usual species kept as C. punctatus is actually a closely related one, but I couldn't find the postChilodus punctatus
