thnx for the replys guys
currently my calcium is at 350ppm but i have been sorting out over the last few weeks going from using red sea salt <the cheap 1> to red sea max which boasts 450ppm calcium, i am hopping this will help alot other than that i do monthly water changes about 15% at a time everything in the tank is fine, just never had much luck with coraline that said ive always used the cheaper salt.
so fingers crossed this might help, ive allready promised i wont put any coral in the tank till i see coraline growing so the sooner this happens the better
quick Q about the water change
my tank is about 300 litres and i plan on doin a 90 litre water change very soon with in the week will the change of salt be to much to change straight over i dont want to do a 5 litres a day or anything like that cos id prolly just be removing the goods i just added
thanx again
