Macroalgae Nitrate Export

[daniella3d]

I have 0 detectible nitrates in my tank and lots of microalgae. Cheato, caulerpa (3 types) and when the nitrates are lower they grow slower, when there is more feeding and nitrates rise (still test at 0 on my tests) then I can see the caulerpa have quick and fast growth.

It just keep my aquarium without any detectible level of nitrates in the water and when the caulerpa grow too much I just prune it. I have some leave of caulerpa that are around 9 inches long now
