    Order of adding fish to new tank (after cycle)

    I’m getting Red Sea Reefer 750 (200 gallon) tank in 2 weeks. After my tank is done with Dr. Tim’s fish-less cycle, I’m not sure if this is the right order to add the fish that I want: Right after tank finishes fish-less cycle Clownfish (2) After 2-weeks with just clownfish (each species added...

    Hi all! Welcome to the build thread for my 40B tank, my first foray into the saltwater hobby. I don't plan to really begin the build until mid-January due to a vacation (to Costa Rica, if anyone has any activity suggestions?!) but I thought it would be best to document everything, in the event...

    ID Moving Brown Specks?

    I have posted a few pics of my tank on here and I’ve gotten a pretty general consensus - it doesn’t look mature and I don’t seem to have enough algae for my pincushion urchin. So I’ve been leaving the white lights on for most of the day, only the blue at night. More algae started growing but...

    ID My Urchin?

    Hey y’all. I’ve been trying to figure out what kind of urchin I have for a week and I can’t seem to get any answers. Google certainly hasn’t helped, but I probably am not looking for the right thing! I really would like to know what type he is so that I can look into the best practices for care...

    Still have algae with low nutrients and how reliable are Hannah phosphate checkers?

    Hi so I have a pretty new tank, only 5 months old about, and I have two things I am questioning. First, I had somewhat high phosphates in July they were about .48, and my nitrates have never been higher than 6ppm on my Red Sea test kit. But I have a lot of green hair algae, which I thought came...

    What are Acceptable Nitrate Levels to Acclimate Fish

    I recently purchased a 65 gallon Red Sea aquarium on Offerup. I currently have a 32 gallon Biocube stocked with 4 fish and I am planning on transferring these fish into the new tank. However, the nitrates in this new tank are fairly higher than my Biocube (40 ppm versus 10 ppm). Is this too big...
