Bashsea ELOS sump advice

[benapilot]

I'm in the process of building my new 150 reef tank and got a smoking deal on a Bashsea ELOS Smart Series sump.
It's HUGE! 36"x24"x16"

All I have is a Life Reef skimmer and a BRS carbon reactor. I'm not really looking to do a refugium... maybe some Marine Pure blocks so I don't have to fill the DT with as much live rock. So I'm thinking skimmer and reactor (possibly run off the same pump) in the second chamber and call it good.... Maybe even have dual return pumps for redundancy.

I'll have three 1" drains coming off an Exotic Marine Systems overflow. It looks like the bulkheads on this sump are 1.5". I'm thinking about just terminating the primary (with gate valve) and secondary drains with hose barb ends and running 1" silicone tubing loosely through the bulkheads into the filter socks. The emergency will be an open pipe just straight down into one of the chambers.

QUESTIONS:
1- Currently I have my BRS reactor attached to the upper brace of my wooden stand. I can do that again, but is there a better way? Can I put it in the sump somehow? Is there a better in-sump reactor out there for a reasonable price?
2- How do I mount my return chamber float switches? Currently I have a ABS bracket from autotopoff.com that fits over the rim of my current sump (29 gallon aquarium). This won't fit over the eurobrace of this new sump. Ideas???
3- Those with Bashsea sumps with the filter floss plastic blocks in the before the return chamber... what are your thoughts on those? Do they work, or a gimmick to be removed? What kind of cleaning regimen, if any, will I need to do?

Good evening

I have not seen that elos but I have a Bashea and they are great. The black sphagetti is there to trap stuff before getting to the pump. It is supposed to come out for cleaning every so often. For some reason mine does not. Either way keep it in there.

As far as what you put in that is up to you. I would put rubble or live rock over bio block in the sump but that is my preference. Same with reactors, I would run them in sump in case of leaks, but again it is preference. I am not sure about your float switches. I use Tunze and the have magnets. Can you use something like that?

Souns like a sweet set up. Send some pics

Thanks!

I'm using my Apex and LiterMeter pumps for my ATO, so unless I get the Apex optical sensors and the box that can interpret, I'm limited to simple float switches.
I don't think I can get the Tunze to work- with auto water changes, Kalk stirrer programming, etc. I like having it all integrated in the Apex. I suppose I could bite the bullet and get the Neptune optical switches and accompanying module...
