Fitting out a Pump room this week (Will order)

[Silencer]

I am on Samui...so already prices at most shops are at a premium, and some over-the-top markups. Ordering on-line saves costs, somewhat offset by shipping costs, and the inability to directly reach out to the seller for any problems. Pool around 80m3. As I am just finishing my housebuild, budget is also an issue. My preferred shop primarily deals with Emaux but can supply any brand. With that as background, major components I will be purchasing are:

 

-Main pool pump (1.5hp), but likely a variable speed pump, for continuous running and multiple turnovers day. Likely will go with Emaux 150 but understand better quality pumps exist (from Heyward, Pentair, Astralpool,...)

- 2 hp Emaux SB pump for spa jets

- 2 hp Greenco air pump for 8 floor bubblers in spa.

- Emaux V700 sand filter (Bobbin wound).

- Salt water chlorination system.  I am looking at Pentair's Ichlor 40 system ($$$) and a Heyward system ($$$$), maybe even a Blu Works system ($$+) but shop is telling me I should consider a system by a company called MANO ($$). From what I can find, they are a Thai company, with some US based components. His rationale is the system is less costly, easy to maintain and has good features. Since finding reviews on Thai systems is near impossible, I really don't want to be a guinea pig. Anyone heard of them or have an experience as a user? Any other comments on the potential major components list?  Sanity check before making large purchase decision.  I understand that if you are not going top end there will always be risk, but hoping to avoid a disaster choice. Cheers.
