Beautiful tank! And greet post with lots of excellent advice. Thank you!! I’m going to check out the Helix heatersI set up a s1000 early March. I now have 5 DT. I use AI hydra lights and AI Nero 3 or 5 power heads, love their app, easy and great flexibility on the light settings/power head options. I run 2 3100 gph Current pumps so I think you would have plenty of room for two pumps. I only use one in my XXXL 750 Fowler, but would set up two if I was to do it over (might even add one since it comes with the Y).
IMO finnex heaters are junk. I will back that with the fact that I am currently using them on all of my tanks. My first issue was in my QT observation system (1 39 and 2 27 drilled for overflows and runnning through a 55 gallon modified sump) stray voltage that I could actually feel the shock when touching the water 200 watt. Then XXL750 one two 500 watt, again started getting shocked when reaching into sump. Didn’t isolate, but stopped as soon as I unplugged them. Then 5 days ago my apex tripped its circuit breaker, reset and it happened again. Unplugged the heaters 2 500 watt and now not tripping. Maybe too much attached, but this is first time and system been running since March.
can’t tell you where to go. Helix new heaters look awesome, but $500 plus for a thousand watt (2 500) system with controller so I ordered 2 600 watt BRS elements and ink bird controller but haven’t gotten yet. Reviews on BRS heaters were sketchy, but all reviews said BRS stood behind them. Finnex won’t after 6 months.
I would recommend Neptune apex controller I use trident for auto alk mag calcium tests and DOS for fusion 1 and 2 dosing. I’m sure what you have picked out is probably just as good or possibly even better, but I use the same items on all 5 of my tanks and only complaint is the finnex heaters. First tank just over 1 year old last tank set up in March. Unfortunately I bought the heaters when I ordered the tank in October so heaters only two months in use.
As far as fish
I like your line up, but couple of thoughts.
I think convict tangs have a reputation of becoming extremely aggressive to the point of killing tank mates, I have read threads where the hippo tang is difficult to keep (I currently have one, had three but two didn’t make it) the two I lost were stupid purchase as my guy at the LFS told me he was giving me the three best as other weren’t eating. However my third that was eating I’ve had since Feb.
Potters angel and gold flake angel reef safe with caution. Definitely a risk to put angels in a reef system. I received an ebli from my cousin, he has had the fish for a reasonably long amount of time and it never bothered a single coral. He decided to quit the hobby and I bought him out. The ebli found something he liked in my tank and then proceeded to kill and eat every one of my corals. Definitely beautiful fish, but double check and then if you go that way I hope it works out well (many have had success).
same applies to the copperbanded butterfly. However I got one to try to help with apstasia. He has cleared it out of my XL 525 and not nipping at corals but I had to do something.
check compatability of two basslets in the same tank not sure it is recommended.
consider some sand sifters (watchman gobies, dragon goby, etc)
Yellow watchman with a pistol shrimp is cool, but don’t think your melenarus will be ok with the shrimp.
Get your tangs and QT then before you are ready to start if at all possible and introduce them at the same time you put in your bristle tooth. I have 6 in my s1000 and put them all in at the start transferred some form the 525 and the others out of QT.
Get your own RODI system if you don’t have one. Get several brute trash cans
Most of all, take your time and keep it fun.
I love this hobby and I love my fishes.
