Hi Guys!
I'm using Fluval in my carts. It's the regular, white Fluval (came in a blue box - Water Polishing Pad - and had 3 chunks of it inside, the box says it's for 104/105 204/205 Fluval Filters).
I don't even use the straw-mod anymore. I was not having much success with the polyfill or polyfill with the stirring straw, and I didn't really experience any difference when I tried the pen-spring cart mod.
When I made my first carts with this Fluval, I did put the little bevel cut straws in a few. I honestly couldn't tell which carts had the straw and which carts didn't.
When I refill or top off a cart I stick an opened paper clip into the corner and just drip the liquid near it and it works great. Most of the time, I'm able to just drop the liquid right onto the Fluval and it absorbs quickly, no worries.
An opened paper clip (or three), small scissors and folded tissue or toilet paper - the things that are always next to me these days - how classy indeed
I actually really like the way this white Fluval works. It holds a good 12 drops of liquid and it actually wicks out. When I was using polyfill, the top of the filler material would be bone dry but would be holding a lot of liquid toward the bottom of the cart.
I do seem to be burning through a lot of liquid though. I'm not sure if I'm just a hard-sucking-juice-hog, or the unusually "hot atties" I have are just eating up a lot of liquid
I find the Fluval to be really easy to work with and not much goes to waste. It's inexpensive and the box I have will last a very long time.
The key for me from day one was figuring out how much filler to stuff the carts with. I over-stuffed and under-stuffed... When I got the Fluval, discovering the perfect amount seemed very easy.
I'm finding it doesn't stick to the atty and burn the way the polyfill had been doing. I haven't had one Fluval filled cart adhere itself to the atty yet. Perhaps, it's because I finally figured out how to properly stuff the carts?
In any case, I find it very easy to re-stuff my carts now. It only takes minutes to re-stuff as many carts as I choose.
I do it every few days. (as needed - I don't like to reuse the carts for long periods of time)
I looked for the Blue Foam in a few places, none of the big chain pet stores or Wal-Mart, etc. had it. (lol - CaptJay - a run on blue foam might have been the issue up here as well )
