My tank is TOO clean...

FWIW, ammonium hydroxide (or just ammonia, same thing in water) won't deplete alkalinity, but ammonium chloride will.

Thanks @Randy Holmes-Farley - could there be any downside to depleting alkalinity with ammonium chloride vs ammonium hydroxide other than just having to replenish additional alkalinity?

Can you mix baking soda and/or soda ash with ammonium chloride to offset the alkalinity decrease? If you can, how much baking soda, and/or how much soda ash, do you add for each gram of ammonium chloride?

You could also dose aminos. That is what I do rather than dose nitrate or ammonia. I have dosed nitrate before.

No, that's the only issue.

If you are talking about 1 g dry powder ammonium chloride you'd add 1.57 g of baking soda to it. Bear in mind that may make it smell much stronger as it frees up the ammonia.

Just feed more. Even fish won't help much unless they are being fed. Feed coral food as well.

Almost 20 years in this hobby and I never thought we would be having issues keeping nutrients up. I have actually switched to topping off with tap water....

why? that won't help nutrient issues, itll just lead to nuisance algae.

What do you think nutrients are exactly?

im talking more about adding unwanted silicates and such. OP wants Nitrates specifically
