2 Questions

I have river rock in my 50 gallon tank that I got out of the wash by my house. I washed and boiled it all. Its been 2 moutnhs after and my filter has calicum build up on it. Is this normal or is my rock dissolving?



Also--- at my lfs there is a discus the ize of dinner plate. Do they usally get that big??

usally rocks dont desolve but it could be leaking calcium in low amounts, if that you might wanna take it out because that could raise the pH, as the for the discus they get big yes, beautiful fish tho

thats why we call them dinner plates..... hehe i would eat or eat off one though. yuk.
but yes givent eh right amount of room and needs they get huge. i agree with Lhutch. chuck the rock. calcium = bad for tank.

pour vinegar on the rock if it fizzles dont use it

I agree with vinegar test. If it does not fizzle then the white stuff is likely limescale build up, this is normal.

What is your tanks normal pH?
Have you seen an increase in kh/gh since adding the rock?

And yes Discus can get quite large (8-10 inches) depending on quality of care.
