This is my favorite in-tank ceramic diffuser. It's low profile, so easy to hide behind some plants, and best of all, it has replaceable ceramic discs so you can keep some clean ones in rotation!

Talking tools, these are important if you use them alot if not then not so much. These tropica tweezers are super nice having a really nice overall feel. Nice and light with upper knurling to keep your hands right where you want them when damp. They also have super positive teeth for gripping your plants when planting to avoid them slipping out constantly and regrabbing and damaging them. So absolutely no more square dull uncomfortable pinsets for this guy!

Noticed my crypt undulata red were not doing well so added one of these into the soil and really made them grow!
