Just done some tested and the results are as follows
I do pwc
every week without fail (approx 25L) using my own RO
water (red sea salt) and can't seem to get them nitrates down.
I best buy some additives to bring the calcium up also by the looks of things, I have a finger coral and a tree sponge in the tank which I feed with some green plankton liquid every other day.
Just had a look at the pic of your tank melosu58.........very nice I must say.
Do you have any tips on how best to tackle my results and which products are best to use?
The clown still looks happy at the mo, feeding well so hopefully he will improve over the next few weeks.
