Hi Mike,

You should be changing 25% of the tank's volume each month. Is it 200L
or 250L?

You need snails and hermit crabs in your tank, which will consume this
stuff. They are commonly referred to as a 'clean-up crew'. There are
lots of kinds of animals you can use, but the favorites are nassarius
snails, cucumbers and fighting conchs for the sand; Astrea, Cerith and
Turbo snails for the glass and rock. You can view these little animals
on my ID page. Turn off your pop-up stopper, and click on the images to
see larger pictures with some documentation for each creature.

My LFS say that it is because my tank is starting but I expected it to be
gone by now.

Answers to the questions:

1) How often do you do water changes? Do you use RO/DI or tap water?
2) What are your nitrate/nitrite levels?
3) How long do you leave lights on in tank? What kelvin/type of lights?
4) Is there direct sunlight in the tank?
5) Do you have snails/crabs/algae pack in you tank?
6) Do you have a sump/refugem?

1) Once per month - 25l of RO for my 200-250L tank.
2) 0
3) 8 hours per day (we are now in winter) 4 x T5's (one blue 3 white).
4) Nope
5) Nope but I do have a phosphate remover running in my Fluval filter.
6) Yes I do.

Is this just as it is a new tank? What am I doing wrong?

Mike
