nope, but been down this road many times...
an old tank that is moved resets most things, now to find the source of the problems
Yes the rock was prev in a tank then dried out in the sun
also remove the ceramic rings. trap for nitrates
you could add a bit of small pieces of LR. the more you have the betteris there any other media i should add to those compartments in the back?
i also added a small 200L/h pump with the bio-cubes so i have plenty of well aerated water moving through them
will remove Bio balls and ceramic rings ( found a lekker groot bristle worm in one of the bags), will add bag of carbon, is there any other media i should add to those compartments in the back?
Purigen, think it can even cure global warming. I have also used Chemipure in the past.
Look in my ex-tank thread for the refugium mod.
