[Luis Taveira]

My new 10 gal. acrilic tank was set up last week and the next day I began to saw some white spots on the bottom of the acrilic and now is all aver the acrilic. I clean it and in less than 24hr. is back again. I dont know if is the salinity that is high or something but I really need help.

Is it calcified?

[goda]

is it outside or inside?

[Luis Taveira]

is inside and now that you said that, I think is calcium. But what can I do to stop that?

[littlemannin]

are you dosing with anything? Kalk and chemical phoshate remover will cause calcium to precipitate ( i guess thats how its spelled)
