SRC Member waterperson Posted April 16, 2015 SRC Member Share Posted April 16, 2015 Recently my tank's Kh been gradually dropping from 8-9 to 5-6 over a month. Corals showing good growth and have outpaced my water change and kalk regime. Been using kalk and i think it has reached its limits for my tank. Need a product to raise alk to 8-9Kh and a way to maintain it there. My tank paras at the moment are Alk: 5-6 Ca: 400 Mg: 1200 pH: 8.2 Temp: 26-27 NH3, NO2, NO3: not detectable Phospate: 0 but got some algae here and there, so i guess its not really zero Pls recommend a method or product to raise alk to 8-9 and maintain it there. Appreciate any comments. Thx Quote Link to comment Share on other sites More sharing options...
xiggie Posted April 16, 2015 Share Posted April 16, 2015 2 part dosing pump or calcium reactor. You will have to raise the kh first , then tune the doser or CR to maintain. 5-6 alk is too low , sodium bicarbonate will help raise the kh to desired level without overly effecting the ph and calcium like kalk will.

FuEl Posted April 16, 2015 Share Posted April 16, 2015 http://www.reefkeeping.com/issues/2005-01/rhf/#7 Can make more concentrated kalkwasser by using vinegar to increase solubility.

SRC Member asg Posted April 16, 2015 SRC Member Share Posted April 16, 2015 bro, how big is your tank and what is your daily kh consumption rate? Quote 子非鱼,焉知鱼之乐... (you are not the fish so you...)

SRC Member waterperson Posted April 17, 2015 Author SRC Member Share Posted April 17, 2015 Tank is a 4 footer. I am dripping in 2 liter of saturated kalk daily but kh still slowly slipping by about 1 kh per week. Quote Link to comment Share on other sites More sharing options...
SRC Member waterperson Posted April 17, 2015 Author SRC Member Share Posted April 17, 2015 Will read up on how to dose sodium bicarbonate to bring up alk first then on a long term dosing method. Probably go with 2part dosing. Wife not going to be happy seeing a co2 cylinder sitting in living room. Will say dangerous for kids. Preemptive strike.

SRC Member waterperson Posted April 17, 2015 Author SRC Member Share Posted April 17, 2015 Just bought this Dupla Marin KH+ powder to boost the kh and the Jebao dosing pump during lunch break. Will dose it tonite and hopefully after few nites, the kh will get back to normal. Thx for all the advice. Quote Link to comment Share on other sites More sharing options...
SRC Member waterperson Posted April 17, 2015 Author SRC Member Share Posted April 17, 2015 oh yes, cannot find the calcium bicarbonate as advised, so used this first to fend off the emergency. Later then scour for the complete solution to boost calcium, magnesium and kh together. Still like to use kalk w vinegar (as suggested by Fuel), so probably use it to maintain levels as well.

SRC Supporter tansk Posted April 18, 2015 SRC Supporter Share Posted April 18, 2015 How much did u mix your kalk with vinegar? Too much of vinegar will also affect your KH.

Just realised sodium bicarbonate can be bought from grocery stores. lol Now reading up on how to maintain Mg and Calcium levels as well. Any idea where I can get Calcium chloride and Magnesium chloride in powder form? I saw bulk reef supply video but their products not on sale in singapore.
