So, should I give it up? hehe
No more bad taste from liquid not properly wicking.
"
Fluval Water Polishing Pad" Rinse well before using and allow to thoroughly dry.
It comes in pads and I peal off layers then cut those into strips approximately ¼ x the length of the pad. Then cut those strips into pieces approximately the depth of your cart (about ¾ because you can cut off any excess.) The layer you end up using will be thin and airy when pulled apart like an accordion. You want to use the least amount possible and it can be quite thin before it starts to leak. Since the Fluval grips the sides of the cart as long as you keep it fluffed when filling you can use a very small piece.
Insert into cart without compressing. If you need to tear off more to keep it light, take it from the layered sides. Trim off any excess that comes out the top of the cart so its flush with the rim. Add
juice and when it puddles lift the Fluval gently about 1/4" with a toothpick or tweezers and let the juice flow to the bottom then you can add a few more drops.
You can use a tiny piece if you keep it fluffed because it sticks to the sides of the cart and doesn't mat down like polyfil... and it can be very sparse before it starts to leak.
I don't have to top off until it needs between 12-18 drops (510s & 901s), depending on the viscosity of the juice. When I top off I fluff the top with a toothpick, fill, then lift ¼ to let the juice settle, push it back in and add a few more drops.
With a PetPerks discount card from Petsmart it was under $4 for a box of 3 pads - enough to fill a few hundred carts.
