almost 3 months since last pic not to much has changed i did add 2 #1 Koralia for the back wall and 2 of the new Hydor Koralia Evolution pumps 1400gph. they are small use very low power and make no noise. the modded mjs are now for mixing salt
I've been thinking about going to those new Evolution pumps...like you said, you could run them on a 9 volt battery, and they take up no space in the tank. Just gotta figure out how to replace 4 powerheads already in the tank and justify it to the wife
