markboy Posted October 10, 2006 Share Posted October 10, 2006 Im using kh doser lets say i top up today my kh will be 8 to 9. After 2 days test again it ll drop to 5.8. Why is this so? Quote Link to comment Share on other sites More sharing options...
Terryz_ Posted October 10, 2006 Share Posted October 10, 2006 It is either that you are using low grade kh buffer or you have corals that are taking in a lot of kh... Another reason might be that your ph is low and burning your kh... Buffer your PH up and see if the Kh will drop so fast... Normally they will drop gradually one... Correct me if i am wrong...

RockyBoy Posted October 11, 2006 Share Posted October 11, 2006 Yup, pH need to be in the right value as well. How's the salinity? Quote Member of : UEN: T08SS0098FMASS in Facebook Reefing in LED Link to comment Share on other sites More sharing options...
mansiz Posted October 11, 2006 Share Posted October 11, 2006 You buffer your PH to 8.2 or 8.3, then you buffer your KH and monitor well, monitor daily to see how much is consumed. Replenish the correct amount. Once your KH is stable, PH will be stable. Make sure to replenish your KH, it will keep dropping. Monitor your Calcium level as well. It will affect your PH also.

SRC Member andylee Posted October 19, 2006 SRC Member Share Posted October 19, 2006 how do u guys top up kH everyday? i only top up every week. and just mix a teaspoon of seachem kh buffer in a cup of water and let is dissolve then pour into main tank. is this way ok? or harmful? cos my fishes will think food is coming when i pour in the buffered water Quote Project R.E.

markboy Posted October 20, 2006 Author Share Posted October 20, 2006 Bro Andy, By rite it should be weekly topping up of KH buffer. But mine when testing found low count so that s why i put up add for advice. Cheers Quote Link to comment Share on other sites More sharing options...
SRC Member chewlaoheng Posted December 24, 2006 SRC Member Share Posted December 24, 2006 I top up using seachem everyday 5ml! PH ok but dKH just can't stay put longer. is there something better than seachem? Quote Link to comment Share on other sites More sharing options...
hammy Posted December 24, 2006 Share Posted December 24, 2006 from what i have been using , seachem reef builder seem to be the best kH addition to the tank , however i have switch to grotech , u might wanna tried that . it is economical for german branded product.

SRC Member planetg Posted December 25, 2006 SRC Member Share Posted December 25, 2006 also watch the MG values as low MG will make it very difficult to maintain KH and CA. Quote Link to comment Share on other sites More sharing options...
SRC Member johntanjm Posted December 25, 2006 SRC Member Share Posted December 25, 2006 Alot of water chemistry here, everything sounds confusing. I split water chemistry into 2 groups, basic and advanced. Basic chemistry invovles: 1. pH 2. dKh Advanced chemistry invovles: 1. Mg 2. Ca 3. PO4 4. etc etc. For basic chemistry: pH is very impt to life in the sea. drop your pH and you will begin to observe corals refusing to open, fishes not eating etc. natural sea water has 8.0pH and may go up to 8.3. in a close environment in the aquarium, in the prescence of lifestock, because of their waste, respiration (exhaling CO2 which is acidic) etc. pH will fall naturally and gradually. Before pH can fall, dKH will fall first. therefore dKH is called a buffer. with increasing acidic compounds in the aquarium, dKh might fall from 12 all the way to 7 before pH will start falling. all this while when dKH is falling, pH stays the same hence we call dKH a buffer. a high dKH value keeps the pH stable. it delays the time taken for the acidic compounds to cause the pH to fall. dkH and pH go hand in hand. Reefmax part A is a strong buffer. it keeps dKH high and thus helps maintain pH. regular dosing of buffers is part and parcel of this hobby. Alot of products out there claim to be good buffers but are actually rubbish. price can be a indication of the quality, but again not everything expensive is effective. Also alot of these additives are manufactured in other countries. their tap water is different from ours. if you go to the states, if you don't use filters in your tap, you can find calcium deposits on your teapots. very obviously the saltwater they put into their tanks will also be different. so what works for them might not work for us. its important to observe and evaluate very objectively the effects of buffers. however, there can be other reasons such as a crappy salt mix. never ever use lousy salts especially when starting an aquarium. there can be a situation where there is no way chemically to raise pH/dKh and the tank will just fail straight out. For advanced chemsitry: PO4 causes your buffers to precipitate out of the water. the buffer that is dissolved in the water crystalizes and comes out of the water making them useless. that means it is another source that reduces your dKH. Mg levels prevent buffers from precipitating out of the water. so this will help prevent the uncessary drop of dKH. pH and dKH may be a simple thing. but the chemistry behind them is actually quite complex and far reaching. use a good salt for water changes, choose a effective buffer. (i've onced dosed an entire bottle of a paritcular buffer and nothing changed. i wonder if its just tap water in the bottle i bought) Quote --------------------------------------------- The Deep Blue Sea in My HDB! http://myfishyroomates.blogspot.com Link to comment Share on other sites More sharing options...
chtan23 Posted December 25, 2006 Share Posted December 25, 2006 pls advise where can I get it and how to use it? Get from this baking shop call phoon huat, refer to the url for their outlets, make sure u get baking soda and not baking powder http://www.phoonhuat.com/sto_loc.htm ps. i'm not related to this shop. refer to this calculator for adding baking soda http://home.comcast.net/~jdieck1/chem_calc3.html the best is u add it in the water slowly and measure the kh Quote Link to comment Share on other sites More sharing options...
