Of course in a marine aquarium we have the anaerobic bacteria working away reducing it. We also do partial seawater changes to reduce it. With high evaporation there are more top ups and the water used is high quality, RO (reverse osmosis) for example. These increased top ups can also help to a very limited extent though this is general quality not nitrate reduction.

I have had tanks that had a lot of evaporation and the water quality was better.

Of course adding components will make things more stable which is ideal in the aquarium.

How times have changed. I remember my early aquariums – dead white coral (much frowned on now and rightly so), the use of tap water as you mention, and getting really advanced with under gravel filtration! I did water changes about once a fortnight for the fish only system and everything seemed fine.
How things have changed though. Most aquarists (this is a guess, I’m assuming most systems are reefs) have reefs and the need for high quality seawater is paramount because of the corals. All of the livestock in our care deserve and require high quality seawater, but it is the corals that really dictate. Seawater quality is effected by the fish load and for example the feeding habits of the aquarist (no, not cornflakes, how the fish are fed or overfed).
I have to say that at my partial seawater change, done once a fortnight, the aquarium seawater has readings no different from the new seawater going in. However, this is stated from what I test for, the basics, so trace elements for example could well be dropping. Overall, it is better to do partial seawater changes even at the suggested minimum of 10%, freshening things up.
Thanks so much for your comment.

In the 1980s I had an 80 gallon (tap water) marine aquarium with no sump (as they were not around then) and an Eheim submerged filter. I had a skimmer and trickle filter plus a section for a carbon bag and a primitive top-up box plus a water heater. All pumps were air-controlled. I had a few corals and fish with live rock. I had this set-up for ten years as I moved to down-size and passed the tank on to a relative. Two fish that I started with (a Percula Clownfish and a Pyjama wrasse) went back to the shop that I purchased them from. OK I was lucky! When I purchased this tank I did not used it for 18 months as I started to do my home work on marine set-ups. Yes in my spare time it took that long plus saving money for the fluorescent lights and such.

In all that time I only done 10% WATER CHANGES ONCE A MONTH. Three days before the water change I filled a barrel with water (which was in the garage), heated it and mixed in the appropriate amount of salt and used an air-filter to air it. What was in that barrel was almost the same as what was in the tank.

Take care

I was obsessed with them! Now they creep me out a bit but if you can get past that, they’re very cool.
