wasp Posted September 21, 2005 Report Share Posted September 21, 2005 It gives you more area for airation which will help eliminate CO2 More area for aeration, and more water requiring aeration. Same dif. You shouldn't have calcium precipitating out of the water, just what is being used by any livestock . When I set up my new frag tanks a few months back I had them running empty for a couple of weeks. During this time they lost ca & kh and I had to replace this. It's just precipitation. If all the ca and kh we put into our tanks was translated into growth and nothing else, many of us would have monsters growing out the top :lol: But really, I'm not at all bothered if someone wants a monster sump. Whatever makes them happy! Quote Link to comment Share on other sites More sharing options...
petplanet Posted September 21, 2005 Author Report Share Posted September 21, 2005 i would say the person with the small sump, they both failed due to the lack of skilled husbandry and the person with the smaller sump spent less money I was thinking mechanical/design/construction failure. Husbandry is another isssue all together. your planned 3 six feet tank will cost XX amount of dollars more to heat/light etc. more pumps needed and your stability is not going to be helped by the same percentage of effort money spent. The big dollars will be the skimmer, other than that it will not cost a massive amount apart from power. The return pump will cost the same as the head height would be no different with one tank than four. Gravity will provide most of the water movement. Lighting hill only be the refuge part. The extra water in the large sump area is just "dead" water. It is not achieving anything by being there. Dead? Bacteria live in it, pods and all the other thinks you can't see live in it. Bottom of the ocean is not dead. Freezing cold, no light, massive presure but there is life. I think water volume acheives a lot. Quote Link to comment Share on other sites More sharing options...

Brianemone Posted September 21, 2005 Report Share Posted September 21, 2005 i think what people are trying to get at micheal is that the cost of 3x 6' tanks vs not gettting you as much as advantage as you would if your where to spend the same money on a bettter skimmer or calcium reactor or lighting or countless other things.
