Anyone every tried anything like this in their filter? -- bio rings (I guess) infused with helpful bacteria. Not sure if they're effective or just snake oil...Maybe helpful in starting up a new tank but not so useful in an already cycled tank? Could they even throw off a well-balanced cycle?
Made in CA, USA, I've just ordered some from a shop at Chatuchak Market and may give it a try. Costs about $25 for a 5L bucket, not overly priced I think -- here in Thailand Eheim Subtrat Pro costs about $25L for just 1L (just got in 3L of that too).
Any opinions would be appreciated.

Benefit :
pH Neutral, do not produce any chemical agent. However if too many added it can decrease pH because anaerobic bacteria too bloom. Freshwater resistant, will not decompose, suitable for both marine and fresh water aquarium, fish pond and other industries PetLifeEliteR CeramicLiveBioRings20TM is very clean by washing processes and disinfection with UV & ozone before add deionized water then add Nitrosomonas and Nitrobacter. PetLifeEliteR CeramicLiveBioRings20TM has area 1,880 m2 per liter more than 18 times the ability to cultvate nitrifying bateria than general ceramic ring. Do not need to wash it with water before use.
Do not need to change these rings after used.
Directions :
Product ready to use.
Do not to washing the ceramic !!!!!!
1) Pour PetLifeEliteR CeramicLiveBioRings20TM with water

To Calculate :
Width (inc) x Length (inc) x Height (inc) x 0.015625 = Volume (liters)
For example
20" x 48" x 20" x 0.015265 = 300 liters
Width (cm) x Length (cm) x Height (cm) / 1000 = Volume (liters)
For example
50 cm x 120 cm x 50 cm / 1000 = 300 liters
