I, after reviewing various reviews on roll filters, recently decided on the Bubble Magus V2 large version.
The objective was to eliminate the use of socks, in which I must admit that I did not have an efficient changing routine. The typical frequency of sock exchange was once a week and the sump only had one sock.
The first notable thing about Bubble Magus is that the device comes completely disassembled, but for those like me, who enjoy building things, it is very simple and intuitive.
The filter installation was very simple since the space in the sump for the roller filter and the skimmer is enough. (50 cm / 19.7 inches long x 40 cm / 15.75 inches high x 40 cm / 15.75 inches wide)
The new filter has been up and running for six weeks now, and I can report the following:
The PH has risen from 8.05 to 8.15 on average.
The water is super clear and all inhabitants seem to be very pleased, particularly the anemones, BTAs
To give more context, I share the general data of my tank:
I installed it in September 2020. Its capacity is 870 liters / 220 US Gal total main display and sump.
In addition to the roll filter, the sump has a refuge area for chaeto algae (that lights up at night). The main drain of the tank is shared with the algae refuge with a tee and through a stopcock, to feed the refuge area.
The most recent update to the system was made yesterday, that I installed an additional return pump, and separate pipeline, to have redundancy.
- A Vectra M1 pump (the one that was originally running 100% 24h) is now for the manifold and the UV lamp. I have it working during the day at 60% and at night at 40%
- A COR-20 pump (the new addition) that goes directly from the sump to the main tank. I have it working during the day at 70% and at night at 40%
