Okay, I am back and after reading a post in the 'What have you done that someone told you not to' poll, I saw someone said that they have a natural tank with chaeto in the tank etc, this might not be the same and I know that replicating and ocean is literally impossible but in my 40, is it possible to have a natural reef tank? I do plan on Copepods and Amphipods and I have around a 3-4" sandbed, the only equipment I will want to have will be - T5s with two Kessil A80s for shimmer, Tunze 9014 Skimmer, Media Reacter for Chaetomorpha, a single mp10mqd (I will only have lps softies and a BTA.), dosing trace elements and a Tunze 3155 with HOB Float Valve) I will aim for a water change every fortnight done by a Auto Water Change of some sort to keep water in balance, Mechanical Filtration done by Filter Feeders ( I want two maxima clams and some coco worms), Bio and Chemical filtration done in another media reacter, Bio first than seperated by sponge some carbon, Tiny bit of Vibrant dosed every week for algae control and chuck some nori in every 3 days and hopefully it sinks to the bottom so the diadema urchin and lawnmower blenny can get it, any other things I should do?
