how to raise kh??

[jOsHiE]

my kh is currently 7.... driping kalk but kh doesnt seems to increase.... intending to dripseachem reef builder raises carbonate alkalinity... but worried it may make my calcium drop...will that happen pls advice....

[nicholas_yeo]

seachem reef builder is okay when u dose it seperately from kalkwasser - shouldn't affect calcium alot. Do not dose them together... not advisable.

Also, if your magnesium is low - getting it above 7 will be very hard. It happens to me too; I dose magnesium to a 'acceptable' limit b4 cont with my seachem reef builder. (Pls use a magnesium test kit to check)

or the more cheaper way.

buy baking soda at those ntuc super markets.

just add in a pinch and it will rise abit. read it somewhere from a book.

i used to do that but not now. using tropic marine triple buffer now.

well... its all depend on u, whether u wanna spend money or not.

all the best.

happy reefing,

Suggest u check your magnesium 1st.... with low magnesium, ur kh is always gonna drop...

Hi.

Im using seacheam reef builder for raises Carbonate Alkalinity.

Im using e powder type to mix with water myself.

For me,it increases my KH n ALK.As for Cal,dun noe y,it increase abitbit when my KH n ALK increases.Dun noe y oso..

Mayb some senior here can advise as im oso curious abt tis..

Tks

Just trying to organize my thoughts...

- dozing Kalk does not increase your kh as it supplements/replaces the daily intake/consumption of your corals in amounts that are proportional to their take up.

- dozing Kalk is a limited to your evaporation rate,

... ie, if your tank evaporates 1.5l of water a day, & if replacing 1.5l of kalk solution a day increases your tank's dkh by 1, then thats fine if you lose 1 dkh a day...perfect.

- Ca will not decrease, with the increase input of alk solution... which is used to set-right the value of your dkh/alkalinity initially. It is not used every-day, unless you wish to bring up the value in stages, but once that value has been reached, it should stop.

- buffers are often use directly to set-right the value of your pH first, and indirectly use to increase alkalinity.

Also, if your magnesium is low - getting it above 7 will be very hard. It happens to me too; I dose magnesium to a 'acceptable' limit b4 cont with my seachem reef builder. (Pls use a magnesium test kit to check)

- Mag is not a function of dkh but of calcium... it is found that with proper levels of Mag, corals will calcify easier

Suggest u check your magnesium 1st.... with low magnesium, ur kh is always gonna drop...

???

- kh will always drop over time, with or without low magnesium, most likely even without low mag, it will drop.

Hi marble!

If you read what the reef builder contain, u will know why..... Reef builder contain carbonate, bicarbonate, chloride and sulfate salts of sodium, magnesium, calcuim, strontium and potassium.

My guess is that Seachem uses : sodium carbonate, sodium bicarbonate, magnesium sulfate, calcium chloride, strontium chloride, potassium ??? salts in a blend that is scientifically proven formula. So when you add this, everything increase abitbit also lah.

Agree on most part of what u said..... As for Mg part..... although it is true that KH will drop over time, with a low Mg it is even more difficult to bring up the KH. I believe many of the reefers experience this eg. Patrick123 and thus lead to a thread on how to raise Mg in a more economical way.....
