On your photo number 3 im lookin at your pipework and thinkin....
1) You have drilled holes in the pipework to create a spraybar effect with it comin out the end as well havnt you??
2) Is the pipework fixed in the tank with suckers along its length to help it stay up?? an if thats the case doesnt the octo pull it down?? my fear is that is exactly what'll happen especially when its at full growth, any thoughts?? i cant rememebr how old your set up is
Nice tank BTW, is that some kinda montipora in the same pic??
Noticed you have another kinda softi ( cant rememebr pic near back left of your tank an can never rememebr name of softi!!!) in there that i want an am gunna put in me nano reef when i get that rollin aswell!!
2. screwed into the black overflow, and has these black "clamps" inside the overflow. 3 years old.
3. the softy on the right is a kenya tree, the ones on the left are zoanthids that use LOTS of light if you want full coloration.
