800 liter with no waterchanges for 3 years

Well, believe it or not. It works for me, maybe i have been lucky, but again the tank is nearly 4 years old. Keeping my eye on the kh balance and my calcium reactor is the key to my succes with sps.
The "new" tank is going to run just as the old one. But i must say that i have been looking at those nice tanks on the forum, running with vodka, wc and some zeo products.
Who knows, maybe it is time for a change :fish1:
Kind regards

I believe that this totally possible but it is out of most hobbyists knowledge of chemistry. If he is able to replenish lost elements and efficiently rid waste in perfect harmony then in theory it would work. However getting the balance would take an extremely knowledgeable keeper and extensive testing to understand needs. This would also include sand bed ", #`s of LR, lighting not to mention a perfect stocking list flow.....the list is endless! It would also be interesting to know if you had any lossess of specimans during the life of the tank? A perfectly balanced ecosystem ....... pure luck or genius

My friend runs a great tank with no WCs on his 155 SPS tank. Corals grow like crazy. I think the larger more established tanks can handle no water changes because they become so stable from the LR/SB and consistant skimming. As long as you dont over feed or add too many fish theres no reason why you cant obtain a waterchange free tank. The key is stability.
large water changes can screw things up in a reef tank. I think smaller more frequent water changes are the way to go if youre trying to adjust levels/add trace elements.

Sorry for late response this tank is about 3 years in took it down for rescaping and so forth and it has had 1 water change after 1.5-2 years due to a massive clam spawning event( main concern was fish health at that point)
I do run a denitrator and skim nicely. It is very possible in fact makles my life soooo much easier LOL
I certainly believe that you can run an aquarium for over 3 years without water changes. To put it simply if you know what you are doing and have the discipline to do what needs to be done this is more than possible.
On a Dutch forum we have an 'advanced' reefer that has been running his tank for almost 6 years without water changes and without a skimmer. Looks better than a lot of aquariums that are running on the most expensive equipment.

I wonder if the LR and substrate will be exhausted quicker by a tank not utilizing water changes than by a tank that implements smaller routine water changes?
Is there a point where the denitrifing capabilities of the LR is used up? The bacteria and micro fauna should continue to its job...Right?
