jonny, yes they are fat awesome fish, the light is a fishneedit.com 65k 150w DE halide, the plumbing is just a bulkhead tied into a 90 elbow with a slip fitting from 1 inch to I think 1.25, I took a grinder and cut wiers into it then on the back side of the bulkhead its a 1 inch T with a cap on one side facing up with a hole drilled into it and the low side has a 1 inch nipple runing 1 inch ID hose to the sump, there is a ball valve in the hose so i can isolate the system if i want to. it works awesome, cost me 12 bucks to plumb it and overflow it, and its really quiet, I got the prop pods and they mush have been in brackish water. they have shriveled and most have gone soft, not alot of hope for those. I have a guy in florida sending me some that were for sure in salt water and he has dome them for 10 years. If the old ones sprout great if not I have a plan B. im planning on putting 40 nassarias,40 ceriths, a couple cucumbers, and some mud dwelling clams. and as soon as better seagrass comes into season im going to make it a full grass bed. also The guy i have had awesome luck with is bamboo-dynasty on Ebay. the guy is great, and he backs up everything he sells and know his stuff so far as mud and mangroves.
