How much water do I have in total?

[lancesmith1]

I have a Red Sea E260 with their sump kit. I have about 60 lbs of BRS Dry Pukani rock in the tank. The display and rear sump has a sticker that says 69 gallons and I think the sump holds around 15. How much water in total would you estimate that I have for figuring dosing amounts? I have been going with 60 but I think that may be a little low.

Why not dose some known quantity of alkalinity and work backwards using a calculator

I am switching over to ESV from BRS 2 part. I am going to start with 15ML per day and see how it goes from there.

I have same setup. Not sure how much rock I have but I have 80lbs sand. Sump running is about 12g. It was close to 70g total when I filled my E-260. Dustin

Never hurts to be a little low on your estimate. Keeps one from overdosing something . ispookie is right .

 

[lancesmith1]

agreed. i feel pretty safe at 65. I will see how things go from there.
