I would recommend a sump to anyone and everyone that has the means, I would also say that if you can have 24 hr lighting down there to put macro's in it. I have macro in my tank because the tang likes it, helps water quality, and I dont/cant have a sump. Maybe I could have one now that I have an actual aquarium stand, but how well do the hang on tank overflows do?
Aeration affects salinity by increasing the evap rate...it might not be major, but many reefers wont aerate because of this. I have to for pH reasons, and luckily my top off is very well documented and is consistent so my corals are happy.
Waves not might remove much, but it is the skimming action at work. There are many different things that filter the ocean, and try as we might I dont think we can mimic any one of them perfectly. Thats why we still have to do water changes.
Corals do need to feed, and mine are feed micro foods, whatever live foods are in the tank, large meaty foods (where applicable) and the best coral food available to us as hobbyists...fish poo. (This is probably the worst thing that my skimmer does)
Thanks kevin for the impartiality...
This all being said, we will take ashlee and the cannucks advice. Does anyone have experience with a HOT overflow? I have always wanted to sump, but thats the only way its going to happen on this tank. What do people think of having two koralia magnum 8's facing each other on far ends? I will add the fours on the back wall where needed when I make the full conversion. (I currently have three fours on my 75)
Thanks
oh, ps. Will have pictures of my softies up tomorrow...mainly for those interested in buying. My for sale thread got shut down because of the fact that it was 50 different sales in one and that I didnt state prices. I feel that everything should be negotiable though.
