Excellent mix of diatoms that will replicate in your system and one of the most important tools you can use when fighting Dino’s - I actually dose this into newer set ups as it gets diatoms growing on the surfaces which in term out compete the other nuisance algae’s which are so much harder to deal with - then once a system is matured / stable you can back off adding silica and let the diatoms consume all the silica in the system - then they will quickly fade away - corals and filter feeders love this stone as well

Slimline Large Frag Rack 13 HOLE
The PNW Custom Slimline Large Frag Rack is one of our most iconic products to date. With a sleek and slim design, it can hold up to 13 frags and barely shade anything below it!
Total dimensions are 10" x 2"
The included frag plug lockers hold your frag plugs tightly and ensure no pesky fish or clean-up crew can knock your corals over and cause damage to them. While holding the plugs tight is their main focus, it also allows you to easily move the rack without having to worry about your frags falling on the way. Available in 4 unique color variations, with standard magnets that can hold up to 1/2in thick.
All magnets are epoxy coated, and then fully encased in clear acrylic for your safety. You can easily inspect, remove, and upgrade your magnet strength at any point in the future.
