Hi Violent Mind.....i mean Violet Mind,
I would not recommend RSM tanks...quite restrictive if you intend to change / upgrade the equipments in future, although it is relatively easy becoz it is build for "plug and reef" kind of model.
Basically, u need to know for reef tanks there are 3 types of fileration - biological, chemical and mechanical.
Biological, we mean the use of bacteria to break down nutrients into harmless nitrogen (NO3)by using liverocks, pellets, bacteria dosing, bio rings refugium system, etc...
Chemical, for eg, the use of po4 remover such as rowaphos.
Mechanical, for eg, the use of filter wool, filter socks and protein skimmers.
And all these types of filteration can be deploy using a sump. Usually reefers use a combination of these methods.
Besides SRC, you can also check out www.reefcentral.com
When u visit the LFS, you can study the tank and the sump system and take some pics for reference.
Make some friends here, they will help u alot in yr reefing hobby....never walk alone....cheers!
