    Large Build Rob's Really Rad 180 Reef Rally

    Hello all! Hopefully the title is catchy, unlike this build thread... I promise this won't start out all that rad :) So where do I start? I usually approach things with the end in mind as that's a recipe for success in my job, but this is for fun so we'll pitch that book in the trash to...

    Build Thread REEFER 500 - STICKS & STICKS

    Hello fellow reefers! My last marine tank was many eons ago, where regular water changes was the norm. Fast forward to 2020, I had initially ordered a REEFER 250, the order was unfulfilled due to COVID 19 and refunded. On hindsight, not a bad thing...I went with the bigger REEFER 500...

    Cor- 20 won’t restart ...

    Cor 20- won’t restart after turning off for maintenance through fusion , it shows a Voltage icon and tries to spool up slowly then shuts off over and over . The cor will only come back after I shut the apex down and restart..... Any suggestions would be greatly appreciated.

    Ok, Just Tell Me Where to Put my Powerheads

    I give in. I keep searching and searching, reading through threads, watching videos, trying to figure it ALL out on my own. But now it is time to just let go and give it up to a “higher power” - the R2R Forum. Trying to find the magic, elusive flow in the tank - enough, but not too much...
