First time in like 6 years having hair algae on my rocks...bought a nylon brush to scrap some off....but wanted to know which inverts( snails, crabs, etc) to get to tackle this issue.
TIA
They are basically the same, one (Aquatic) has all the pieces you need to connect it, you just have to figure out mounting and such. The other (Aquatic Life) has the same part all wrapped up in one complete unit, total plug and play...
