The tanks will be insulated behind the fish room that will have its own draw of air and exhaust from outside in the hopes that will fix any moisture and heat buildup.

A question to those used Spa-flex.should the 1.5" spa flex it tight like a PVC on any fitting or should it be loose and use some kind of transition fittings.Because seems like mine fit loosely in the fitting and I bought this product G941HT… SPA FLEX from www.greenlinehose.com/
and the specs says 1.5" spa-flex with ID 1.65 AND od 1.90

I searched on G941HT on that site and came up with this: http://www.greenlinehose.com/_pdf/hose/2.Water.pdf#search="G941HT"

... which I have to say looks like some kind of rubber? That's not spa flex. Spa flex is, literally, flexible PVC pipe. You use PVC cement same as like for rigid PVC (you can use regular PVC cement but the flex PVC cement is clear because it has a little bit of give to it) and yeah the fittings are ordinarily a pretty tight fit (same as rigid PVC would be - it's the same fittings).

this is the information on the product I bought as it is on the bottom of the spec sheet

Spa Flex Hose is designed to replace PVC pipe on Hot Tubs
and Spas. G941HT has the IAPMO plumbing safety approval
and uses the same external glue-on schedule 40 fittings
as rigid pipe but is much easier to install. Hose will bend
without heating and will follow the curves and corners on
a spa without having to use elbows. Spa Flex is ordered
by nominal pipe size.

G941HT… SPA FLEX
Construction: Cream coloured, flexible PVC, embedded with a
rigid PVC helix.
Interior: Flexible PVC, smooth for unrestricted flow.
Exterior: Smooth, cream coloured, weather resistant PVC.
Temperature Range: -20°C (- 4°F) to 65°C (150°F).
Note: Please use a PVC-to-Flex cement for attaching PVC fittings
to hose. Suitable cements include:
– Permalite Plastic #VIC 504
– Uniflex Pipe Cement
– United Elchen 6700 Series PVC to Flex
– Weld-On #795 PVC/Flex.

And these are the specs I asked for

size 11/2" model # G941HT-150 I.D. 1.65" O.D. 1.90"

And by measuring the ID and OD of what I bought I think they gave me the wrong size as it measures to the same specs as the 11/4" spaflex
Back to the store tomorrow to replace the size

Elias, that G941HT is the correct stuff. It is normal for it to seem sloppy after it cures. This is why it works so well.
Make sure you hold it in place for a few minutes while it starts to cure as it can slip apart much easier than rigid pvc.
Not sure what cement you plan on using, but anyone I talked to recommended Weld-On 795 and it worked well for me.
