Men jeg overvejer at hæve.
Metabolismen afhænger i jo høj grad af temp for de koldblodede. Hvis man gerne vil ha gang i væksten så er det med at få temp op, ellers kan man risikerer at spilder kræfterne ved at dosere, nuke med hqi. Men det gør også balancen (i teorien) sværere at holde, og varmt vand indeholde bla. Mindre ilt. Større fordampning, højere elregning osv.
Dr. ron smimek (kendt fra reefcentral, har argumenteret for højere temp).:

”Cold Temperatures Are A Problem
Although aquarists are often concerned with the effects of high temperatures, the effects of low temperatures are equally deadly. A recent study shows how differences of only a couple of degrees Celsius determine the distribution of Montastrea annularis populations in the Gulf of Mexico and in the Caribbean Sea, proper ( Carricart-Ganivet, 2004 ). In this case, the no growth lower limit of zero calcification occurred at 23.7°C (74.7°F) in corals from the Gulf of Mexico and at 25.5°C (77.9°F) in corals from the Caribbean Sea. It is worth noting that prior to recent bleaching events that some of the richest coral reefs, often dominated by Montastrea annularis , in the Caribbean were found near Belize. In the mid-1970s, these areas' average monthly temperatures were generally above 29 ° C, (84.1 ° F) and the monthly maximum temperature may reach 33 ° C (91.4 ° F) (Highsmith, 1979a. b; Highsmith, et al., 1983). Montastrea annularis appears to have a center of radiation in the Belize area, as do most other Caribbean corals.

altså væksten standsede allerede ved 25.5c for nogle
koraller, og gennemsnit temp var hele 29c.
han konkludere vidst, at den bedste temp er 82f eller 27,8c for
koraller.
