Excited to start on my third tank! Currently have a reefer 250 and have just ordered a 525 XL deluxe. Would have liked to go a little more creative with the build instead of the deluxe model, but I chose it for 2 reasons. Was not sure if other light mounts would cover the "plugs" red sea puts on the "non-deluxe" tanks, and I'm not opposed to AI lights, not to mention it was a pretty good deal considering buying all the lighting and mounts separate. Current Plans: - 90lbs reef saver rock - 60lbs sand (should give me 1" bottom) sand type TBD - 2x EcoTech MP40's - Bubble Magus Curve 7 skimmer - Tunze ATO to replace stock reservoir/float valve setup - Jebao DCP-10000 return pump - Red Sea ATO reservoir conversion into refugium - reactors TBD, but will be running at least carbon - After tank cycles, will bring over my dosing pump for 2 part/NoPox from old tank - Hard plumb return/refugium? I will post pictures and updates as the process begins!
