Michelle Rees –
Works well with my air pump. The blue color is nice and it keeps the water well oxygenated. Easy to install and fits perfectly with my existing setup.
Paul Scott –
Good quality and small size. Fits my tank well and adds a nice touch. Aeration is noticeable after a few days of use.
Ruth Parsons –
I’ve used this for two months now and it’s still performing well. No clogging, and the airflow is consistent.
James Bower –
It works but the airflow is a bit weaker than I expected. Might need a stronger pump to get full effect.
