I HAVE A NEW SETUP WITH A 90GALLON TANK. NEED A GOOD HANG ON SKIMMER. WHAT DO YOU ALL RECOMMEND? I COULD ALSO GET A REFUSIUM UNDERNEATH AND PUT A SKIMMER INTHERE BUT I DON'T KNOW HOW. IS THIS HARD TO DO?
Have not used it personally but people rave about the aquaC remora pro with the mag 5 and surface box. it is pretty readily available on aquarium supply websites.
The aquac is the most recommended but comes with a price tag lol. You can buy pretbuilt refurgiums that come with all plumbing and everything you just add sand or mudd and plants and inverts you can buy them for $200 to $300.
