I am designing a new sump and have a question....
I am having an issue with my sump design... My skimmer needs about 9" of water and I would prefer to have more than 9" of water for my fuge...
I put them down low. They were only about 4" from the bottom.
Alk is around 9.
Thanks... I had the light rack custom made. Each AI can be adjusted left and right and the whole unit goes up and down. :)
I got stuck by a bunch while diving in Mexico. Take tweezers and remove the spine broken off in your skin. Other than that they are pretty harmless.
On a separate note, many omnivores like to eat urchin. I had a sohol and a naso that would eat them in less than a day.
