Aquaponic Supplies in Costa Rica

Glancing at past posts they are all a few years old.  So for 2022 now, can people tell me of parts sources for Aquaponics in Costa Rica?

We are making a DWC system and have yet to find: a regenerative air blower, Matala filter pads, BioMedia for a moving bio-bed like K3, air diffuser tubing like Aero-Tube, air diffuser discs, rafts (either to make our own from blue DowCorning type closed cell foam, or something like the pre formed Beaver Plastics foam rafts).  Also a good supply of fish food for Tilapia is needed.

Thanks for any advice/links.  Appreciated.
