Hey Dr novak the audio sounds great thanks for another great video all 33 of my aquariums are using the slow moving plenum and yes it works fantastic here in the UK I can't find baked clay cat litter for love nor money but I have tried all sorts of substrates from fluorite red used a clay bonsai medium tried zeolite but found that drops the pH too low I have used plain pea gravel used fluval stratum tried aragonite crushed coral and out of all my tanks using a wide mix of mediums I found the (KITTY DAMMA) bonsai medium had the best plant growth but all the tanks are healthy fish are breeding no unusual live barer deaths its just a fantastic filtration method thank again
Some on KZitem are claiming the use of kitty litter as a substrate sucks out all the nutrients and minerals necessary for fish life.

I never gave it a thought that the sound was bad, some viewers must have super hearing. On another note, I have a question about kitty litter. Some on KZitem are claiming the use of kitty litter as a substrate sucks out all the nutrients and minerals necessary for fish life unless the kitty litter is "charged", have you heard this and is there any truth to it. They use the word "charged" to mean saturated with the necessary minerals.
