Hi all

Experiencing some issues with my new marine setup.

My live rock is turning white, it has started over the Last two days. Wondering will the temperature cause this...?

Went away Wednesday morning temp was 25℃ which it has been since I set the tank up 10 days ago.

Came home tonight and heard a popping sound that came from the tank. Checked the tank and noticed the temperature was into the high mid 30s and the heater had gone.

Water changes are not going to sort out the levels of calcium and buffer,

it may work for a fowlr tank though

if you use a high brand of red sea coral pro its more natural then adding tons of solutions i have added tons of this stuff over the years and i found out weekly water changes are the best way, it may take the while. and save you alot of cash in the future,

You should consider buying a STC1000 temp controller unit. At least if you heater breaks the temperature is still controlleed. You can find them on ebay cheap.

sorry mate but ur way off the mark here it does not matter what salt in the world you use, take a tank like mine i have to dose 56 grams of buffer per week to keep my alk steady at 10 i then have to add 42 grams per week of calcium to keep that steady at 420, and just to clarify this is divided into daily dosing for a stable tank

so you could imaging the drop in a week if their was no dosing

even if you done a 90% water change the salt that you mix can not bring up the levels, the bucket of salt has the same everything in it and cant bring up what is not their

if you were to add say 50ltrs of new water to bring up falling levels if that was to work the 50ltrs you just put in would be depleted

dya get me

I was recently in a guys house who had a small sps tank,i'd say probly 80- 100 liters andhe told me all he done was water changes and didnt dose for anything..

But what jeffs saying makes more sense...if your cal is down 20 ppm and you do a 10%water change then you've only replenised the cal in 10 % of the water....90%of tanks waters cal is still down..so you have to dose...a water change is not going to sort it out....
