I thought it was going to be expensive too, but I ended up not having to change the media nearly that often. You can also buy it bulk.Wanted to add a CO2 Scrubber checked the prices looks cheap ... but media should be replaced every week. And it's like $350 dollars a year for the media ! And this is the cheap one from BRS.
The volume of air used is very little.Ok, now I have the air coming to the skimmer from outdoor all the time and bubbles for 8 hours during the night. I will post my pH chart in a week. Thank you again for the help.
I was also wondering, cold outdoor air or hot during the summer will affect very hard the temperature of the water?
I've used something similar to this method on my past tanks, the first time I seen this was back in 09 on Joe Weatherson 240g tank.
here is his TOTM Thread and Video he posted years ago. I've had good results in the past using this method..
Yes, very similar but using pressurized air. It was based on the 2001-2003 methodology of introducing aeration/bubbles/surge into a reef tank which proved to be very beneficial.
It was the about the same time we started using the wooden air stone instead of a surge tank or pressurized air injection and were just as successful.
If you have a picture, that would explain a lot more.I've put a wooden air stone before my refugium but I'm getting scum on the top of the water where my return pump is located, should I move my bubbles to the return section?
