Is it an ok idea to use a ready made setup like this for octopus mercatoris: http://www.redseamax.com/redseamax/250Temp/redseamax/Red_Sea_MAX_HP_130D.html Maybe with some mods to increase the amount of protein skimming or whatever is neccessary. It's possible to just get a 30 drilled and work from there, but I'm wondering if anyone thinks its a particularly bad idea to get something like what I linked to and use it as a tank for mercatoris. I don't want to cut corners but maybe it's smart to get a setup like this, economically and practically. I assume there would be mods needed but that may be easier than starting from scratch. I have seen people say there are problems with overheating on these small all in one tank setups but I assume the low level of lighting needed for a mercatoris might balance that out.
