hey guys so after a 3 year break from reefing ive decided to get back into the hobby!! Im looking for some advice for starting a new tank again. Wondering if theres any new/upgraded tech i should buy or new tricks of the trade i can learn so i can keep my reef nice and healthy. I was thinking of getting a 40-50gal rimless (unsure of the brand yet) using 2 hydra 32 as lights and 2 nero 3 pumps. For filtration ive always used a simple HOB filter live rock and sand and do weekly water changes of about 15% and dose as needed. For heater i like the titanium heaters. Other than that thats pretty much all ive ever done and have had good results but im wondering if theres any new ways to make it even simpler/better. Its going to be a mixed reef but very litte sps more LPS and softy but i like having my tanks PACKED FULL lol. Also want opinions on which salt i should use ive always used red sea coral pro but have been thinking of switching to tropic marin pro. Please let me know what you guys think and any advice you can give. I really want it to look like my 20g did before i broke it down (but with smarter coral placements lol).
