Thanks for selling these!! I always stuff too much polyfil in the holes or not enough! Finally I dont have to go through the trial and error on how much to fill the holes with!! These things are great and really durable! Do you guys offer these in larger quantities?? I will send an email too. Peace!

So much easier than screwing around with polyfill. A simple tweak that will keep your tub happy, healthy and growing like gangbusters.

I love the tub filters. They are just as good as others that I’ve used and are a fraction of the price. Love you guys

Using these on marther chambers and totes is simple and effective.

When making or using tubs or anything else that requires oxygen and carbon dioxide flow, these patches are the best.
