Basically in a low tech tank should I be running a bubbler?
Options I have are:
Air driven sponge filter - large bubbles
Skimmer with Venturi - adjustable but lots of tiny bubbles
Basic air stone
If it is a good idea then how long should I run it for, and during lights on or off?
I was initially running the filter with a spraybar which was providing good surface movement but kept submerging my few floating plants. I also got some surface film/scum so added the sponge filter which resolved it, but this was later removed for use in a shrimp tank.
I have now directed the spraybar down a bit so floating plants are happier. I also added the skimmer below the surface (so not actually skimming) to provide more flow at the rear of the tank.
Bubbles do seem to help move the surface around but I don't know if they are beneficial overall.
120l Juwel lido 61cm x 41cm x 58cm
Set up about 5 weeks ago. External cannister filter.
2x original T5 tubes, one with reflector angling the light away so not full brightness.
Fine sand/gravel over soil
Dosing 10ml TNC complete per week
Lights currently on for 6.5 hours with very little additional natural light.
No CO2
No livestock other than snails
Cryptocoryne wendtii green
Hygrophila corymbosa Thailand
Anubis's heterophylla
Microsorum pteropus
Unknown stems
Unknown swords
Unknown moss
Salvinia minima
