For the amount of bio rings you get, you will have a hard time finding it at a better price. Comes in a large mesh bag. I think I could divide this into three Aqua Clear HOB (20s or 30s) easily. Good value and quick shipping. Cory treats you right. I live in a small town that does not have a pet store. I try to patronize a couple of shops in neighboring towns but since I got back into the aquarist's life, and stumbled on Cory's Youtube posts, I have also tried to send business his way. Small price to pay for all the information he provides. Always quick to respond to email questions. Thanks.

Put these Bio Rings in my HOB filter to improve the bio load on the tank. I have guppies having babies every day it seems need all the help I can get to tackle the increasing load. Also use your filter on intake for a pre filter. It keeps fry out of the filter and also increases bio load. Have learned a lot from your Video's, that's why I support you and your company

After doing more research, I found these bio rings, and decided to purchase them. I’ve been keeping fish on and off for about 10 years, and one is always learning about this hobby. I ordered them along with the bio ring bags, and put them in the back of my Marineland Emperor 400. My fish look healthy, happy, and have a happy owner. Definitely going to purchase more when I get another fish tank.

The bag came with more than expected it can easily be split amount a few different 20/30 gallon Hobs. If you plan on using with a few filters I'd recommend getting a few extra filter bags to split them up.

These rings are new to me an have made life easier for me! Pricing an shipping are great! They are a welcome change to old style filters! Thank you
