Coral looks great Kevin! I'm curious what tiles are you using for your acros?
Hey, Tim. Thanks for dropping in and looking.
These are granite 4"x 4" tiles from Home Depot. They are sold in a clear plastic sleeve with about 10 pieces for $5.00. The are unfinished and rough cut so there is no shiny side.
I went to this because with a shallow display I do not want to eat up space with live rock. The live rock also displaces a lot of water which I need to increase my water to coral ratio, which improves tank stability.
The tiles are much easier to service and keep clean. They quickly encrust and the rest covers in coraline.
I keep Matrix in the sump for the bacteria to colonize instead of depending on liverock. As a 70 gallon tank and sump, I had 5 liters. Now as a 140 ish gallon system, I have added about 10 liters more. I hope this can keep up until it is colonized and not kick off a nutrient storm. I purchased a 20 liter bucket on line for about $90.00 so I have 10 more liters in reserve if needed.
I believe there is a good and bad trade off to every decision in life. In using the tiles, I trade off a natural reef look in return for ease of service, higher water volume, and a much cleaner, detritus free tank. In a shallow tank it is then very easy to syphon up any detritus during water change or with a turkey baster.
Sorry for the soap box rant.
Kevin
