Hi everyone.
I recently started reading up on the methods and results obtained by Cruz Arias on generating micro-nano-bubbles to "deep-clean" and inject new vigour into reef tank systems. I have been trying this method and there have been some interesting results.
Basically the method is very simple, pump air through a wooden airstone,to create micro bubbles and then use the cavitation and head pressure of your return pump to "shrink" these bubbles down to an even smaller (nano) size, where they blow like fog into your DT through the return lines.
Nano-bubbles are typically 1-50 um in diameter,negatively charged and move in a haphazard fashion through the water column for long periods of time through Brownian motion.
The bubbles are said to remove detritus and algae from your rocks, sand and glass, clean up diatoms and cyano, increase the ORP of the water and raise the pH by driving off CO2.
They are also said to penetrate the pores of your corals, removing unwanted mucus, sebum and bacteria.
Oxygen is claimed to be delivered more effectively into the coral, fish and invertebrate membranes.
Fish are also said to have more vigour, display continuous grazing behaviour and show improved colouration!
I have bubbled every night (12 hours) for the last 5 days and have noticed the following:
The first 2 nights of bubbling produced large amounts of mucous from the Acropora, but stopped after that. Corals are displaying increase PE, appear brighter in colour and I've noticed some budding on a few species.
Water is much clearer, sand and rock work are noticeably cleaner!
Water has a fresh ocean smell to it
Fish are very active and graze constantly!
Any other reefers tried this method and achieved noticeable results out there?
I'd be keen to read about your experiences
Cheers, Tony
