I just posted an article about reefs' top 3 favorite new products:

Mastertronic by Focustronic
ClariSea Gen 3 fleece filter
Polyp Lab cellphone clip V2

What's yours?​

Positive results for investment is definately the Avast K1 Kalk stirrer for me. Easy to control steady 80% staturation when over 3 liters a day, and SPS love the high Ph( 82. to 8.4) envirnment.

What is old is new again for me.
