No water changes

[Jonowilliams]

I know this has been a popular topic across the forum but after some searching I've not seen people state what and how they run things to have a successful no water changes tank.

My current tank hasn't had a water change for 18 months or so, however I've always had nitrate at around 50ppm.

Phosphate has always measured pretty low at 0.04ppm but I suspect it's higher due to some algae growth.

In the past to try lower my nitrate I have tried a sulphur reactor that never done anything after a few months. Bio pellets since starting the tank, chaeto and caulerpa since starting the tank too. Most recently I tried vinegar dosing with no results.

My system is around 700 litres and minimally stocked with fish.

Details
Never ran PO4 remover
Bio Pellets in an H2Ocean reactor (finally after a year they're being consumed very slowly)
Reef Octopus Classic 202s
Chaeto and Caulerpa reverse lit with 2 aquaray tiles
500ml of aquaforest zeo stones in a bubble Magus reactor

How do you guys and girls on here successfully run a no water change tank?

Thanks
Jono

Google Glen Fong if you want to read about zero water change.
He also has a thread here.
