When we aquascape and tend to our aquariums, we hate the inevitable algae build-up on our tanks. And just like with any hobby, the mark-up on the products geared towards it, is typically marked up a couple hundred percent. So, I'm always on the look out for budget ways to fund my hobby.
This one in particular comes at a fairly steep price of $11.99...but for a pack of 48! Now, please consider there are plenty of other options that are below $10. Also note that these are the two most bang for your buck with good reviews.
