Hi Joe,

I m using Tetra NO3, I though ite reading is 0-12.5,12.5-25,25-50.... If you do a bigger water change of 50% or more, u will c a different.

[Anthony]

norman. ya my NO3 Always fall inbetween that range 25-50.

wah 50% change nt abit too much?

my tank just 2ft. i scare the fishes cannot adapt to it.

i think if the salinity and temperature abt the same, there shdnt be a problem...

if still worried do it slowly over a few hours lor

[Anthony]

hmm i think today i gona took all my LS out.

*remove my C5 sand + the UGF plates below. to replace it w C3 sand abt 4" enough rite. 6" in a 2ft tank look damn ugly leh.

bioballs are called nitrate factories not because they trap dirt but because they are too efficient in coverting NH3 -> NO2 -> NO3

infact bioballs are self cleaning, they are less likely to clog compared to siporax or other ceramic materials

So either you get more nitrite or nitrate.

most likely ended up as nitrate

as the 2 type of bacteria that coverts NH -> NO2 and NO2 -> NO3 needs a similar aerobic breeding environment and most likely will be neighbours

4" also quite big right?? I have mud type sand in my main tank ard 4 inches plus one inch 1" coral sand.... Dunno good or not also..But at least nothing's dying.

We can't the wetdry if it creates lots of nitrates because it is just doing it's job efficiently. It is our fault for overstocking or overfeeding and adding to much ammonia to the tank. Otherwise we might as well blame all open surfaces in the tank for letting denitrifying bacteria grow there

We can now conclude that wet drys are Not nitrate factories.
