Yes they are very close together. I got so many anemones in that tank, It is hard to find the room, and keep them from killing corals. I got to rethink this tank. I think I will remove the Magnifica. Just the carpet and limited to 3 Haddoni and 3 Gigantea.
Minh, pick up a few of these:
I love em! Get the 425's.
Also, I've noticed that when I get sick Nems out in 6-12 hours, the rest rarely get sick. If I wait 24-48 hours, it's too late (most of the time).
Also, I've been seeing how long I can push WC's with Gigantea's in HT. They typically start to droop in 2-3 days. By 3-4 days they're half the size.
Changing the water every 24 hours is vital. IMO it's as important as dosing meds. You should have great results changing the water BID Minh.
Ohh, if you need a cheap light that works, get a Utility Tech LED Par20,30, or 38. Both the lights and cheap clamp fixture ($5) are at Lowe's. I usually take the hood off, and just suspend the Ceramic socket over the water 6-24" and it's done well for Haddoni, Gigantea, and Magnifica.
Good luck brother. Keep us updated.
