I have a 125 gallon long cichlid community tank. There are two eheim 2217 canisters on both corners and two plates of PAF UGF in the middle. Each plate i cap one and use two lift tubes. Both tubes on the same plate share one whisper 40 air pump.
When I first ran the air pumps 4 months ago, it made a lot of bubbles. now only little bubbles came out. Each time I changed the water, I cleaned the airstones by brushing the exterior. So far the water is clear but I am worry that there is not enough air flow for the ugf. I perfer air pumps to underwater powerheads because powerheads generate too much heat.
Here are my questions,
1. Do I have to have airstones to run the ugf?
2. How do I clean the airstones properly?
3. Should I replace the airstones came with the ugf with other airstones?
4. Should I buy two more whisper 40 pumps so each lift tube has its own?
5. Any other suggestions are welcome.
Thank you in advance.
