I, know that a reef tank does not have the same water conditions as a standard horse tank. But aren't there horses that can take 80 degree water. The horse tank would be 30 gallons. and sparsely scaped. Also Ive heard of a product that can bring down a tanks temp 2-3 degrees. Put this on horse tank and limit flow to reef. I would also like any input on putting these systems together no matter the livestock. Plumbing. Stands. Pictures of course always help.
