I'm running the GHL & happy with it, but surprised how once introduced, the corals demand very quickly increased to the point where I'm dosing 2 ml per gal.of brs recipe 1 in about 55 gal of water just to maintain 120 ml Ca & 110 ml alk are added daily. The amounts are different because I switch from salt to salt weekly for water changes causing a higher average alk addition than Ca addition, & When I get into my big build I may look at a reactor though to see if there is even less work & if it maybe cheaper in the long run.

ya you kinda need to be a mad scientist for a couple weeks while you get things dialed in, but then after that its just routine checking from time to time to see if all is still well......





chugalug chugalug chugalug......happy corals are needy corals:wink:........I was going through a gallon of each of Ca and DKH (Randy"s recipe) in about three days:surprise:.......now there were some thirsty corals:lol:

Thanks for chiming in Doug. I was kinda wondering what a tank like yours in it's first glory was taking on a ml per gallon ratio? & by the way you wrote "Couples Weeks" kinda insinuates you my be away on an upcoming vacation.???:)

couples weeks????.....hedonism here we come.....pack your bags baby!!!!:lol:

This article puts forward reactors are cheaper bigger the system

his receipe has like 5300 DKH in the gallon if memory serves your tank was going through that much seriously???



anyways mine last about 35 days and i seem to always have about 150 ml of calcium left when the alk is empty dont know why the dosers are the same and timing the same and levels stay constant but it works

funnily enough tho i read that RHF doesnt dose his 2 part recipe. He uses Kalkwasser. That is also what i use for my tank and i find it even easyer than 2 part dosing.

I found that when I was using baking soda I needed to add nearly double the amount than calcium. When I switched back to 'reef ready' stuff like Coral Grow's alk additive it went back to being nearly 50/50.

Dosing only complicated if you do it wrong and all your pumps fail from precipitation in the span of a week. oops.

I just did some tests for the first time since last week & the dosing levels are going up again to CA 144ml per day & Alk 138. MG is @ 1350, in the 3.5 months I've had this doser online I've had to increase the amounts fairly substantially almost every week, & I've yet to dial it back. I hope that maybe these new #'s may level it off for a while.
