Dosing question

[Jim]

Hi everyone. What is a normal dose of 2 part in a 90 gal? I have to keep raising my dose and I'm usually at the low end. Cal 410 Alk 8.6. Right now I"m dosing 70ml daily,is this normal?

dosing 2 part is totally dependent on your ca & alk par. each tank is different. if 1 par is unusally low, it may b cause by other par being outa wrack. just increasing dosage may not be the answer.

i have a 125 gal i only dose 30ml and it work my cal right now is at 470-480
i have esv b-onic and it 4ml per 20gal i think

a quick way to gague your current calcium demands (and therefore how much you need to dose) is to measure your calcium, wait a week without dosing or waterchanges, and measure again. divide by 7 (or however many days you waited) and you will have your daily calcium consumption. 1 ml of B-ionic will raise the Ca of 1 gal of saltwater approximately 16ppm. with these numbers you should easily be able to figure out how much you need to dose.

you should still test occasionally as when your corals grow your daily Ca consumption will also increase...
hope that helps.

What's your Mg level? It may be low which is why your dosing so much. Mg helps maintain Ca and Alk levels.

magnesium is very important. at one point when i first started i kept on dosing 2part calcium and alkalinity every day and had no Coraline algae growth. until i got my magnesium levels where they were supposed to be. and i also had to dose less two parts after i was maintaining my magnesium levels
