chtan23 Posted June 20, 2006 Share Posted June 20, 2006 if you raise your kh, ph will go up, but do it slowly Quote Link to comment Share on other sites More sharing options...
SRC Member lyz77 Posted June 20, 2006 SRC Member Share Posted June 20, 2006 Try salifert KH buffer! U can try to DIY a container and mix the KH to drip slowly into your sump in order to maintain or increase the KH level slowly! Quote Link to comment Share on other sites More sharing options...
M4rk4nth Posted June 20, 2006 Share Posted June 20, 2006 If your KH is 8+ how can your PH be 7.5? Some thing wrong with test kit? or PH meter not calibrated? I made that mistake by accidentally pressing the calibrate button when testing tank . Using any sulphur denitraters? don't directly discharge the outlet into your water.

SRC Member JeffL Posted June 24, 2006 Author SRC Member Share Posted June 24, 2006 now i blur liao i am using seachem test kit for KH its says i should have KH from 4-6 meq/L, some of you said 10kh is it different units? from the test my KH is 4 meq/L Quote 2 Feet Tank: (Decom Feb 2015)-Lightings : Pharos LED light 90W with wireless controller-Chiller : Arctica 1/10HP with H2Ocean Flow Pump 2000-Wavemaker : Vortech MP10ES -Skimmer : Bubble Magus NAC 3.5-Return Pump : Eheim Compact 3000-Reactor – TLF150 (Mod) with NP Biopellet-Reactor – TLF150 with Rowaphos Link to comment Share on other sites More sharing options...

SRC Member madmac Posted June 26, 2006 SRC Member Share Posted June 26, 2006 now i blur liao i am using seachem test kit for KH its says i should have KH from 4-6 meq/L, some of you said 10kh is it different units? from the test my KH is 4 meq/L This article explains it very well. : Chemistry and the Aquarium: What is Alk. Excerpted from the above, are two points which I hope you can grapple with : So what we are doing is using a very simple alkalinity test as a surrogate measure for bicarbonate and carbonate. Since these two substances comprise the great majority of alkalinity in seawater, it is safe for most people to equate alkalinity with "availability of bicarbonate and carbonate for my corals". .... Finally there is the German term dKH (degrees of carbonate hardness), or just KH (carbonate hardness).Strictly speaking, it is the same as the carbonate alkalinity (AC in equation 8). Unfortunately, it is a very confusing term, as it has nothing to do with hardness. .... Consequently, most hobbyists should think of dKH as simply another measure of total alkalinity. The results obtained with such a kit (dKH) can be divided by 2.8 to yield the alkalinity in meq/L. You're are testing for alk, units are in meq/L, and confusing with dKH. (both are alkalinity test) The conversion is a multiplication by 2.8 for your case. So 4 meq/l would give you a dKH of 11.2 Quote Link to comment Share on other sites More sharing options...

hammy Posted June 27, 2006 Share Posted June 27, 2006 so my kh is 11.2?? then how come my PH still so low maybe ur test kit is inaccurate. get another one to confirm. it is dangerous to have pH at 7.5 only for marine Quote 2x1.5x1.5 tank Lighting: AI hydra 52HD Skimmer: Deltec SC 1455 Reactor: Minimax; rowaphos Skimz ; NP biopellets Wave Maker: MP 40 WQD Return pump: Eheim 1262 Chiller: Arctica 1/10 hp A righteous man cares for the needs of his animal, but the kindest acts of the wicked are cruel -- Proverbs 12:10 Link to comment Share on other sites More sharing options...
SRC Member madmac Posted June 27, 2006 SRC Member Share Posted June 27, 2006 so my kh is 11.2?? then how come my PH still so low Because while they are related, it doesn't mean they are the same. Your Alk measures the carbonates, which 'buffers' or cushions the rise and fall of your pH. The more carbonates you have, i.e. the more alk, the less volatile your pH will be as it 'buffers' the daily swing your tank pH will go thru. Generally speaking, your pH will keep rising until late afternoon and then if falls to its lowest point just before dawn. Depending on what time of the day you test. You may not have known, but the daily pH can swing from 7.8 to as high as 8.4... and these are generally acceptable durinal ranges. So pls tell us what time did you do the test? Is yours a test kit or are you using a calibrated pH meter? A consistently low pH is almost always because of two things : a dirty tank or excess CO2(an ill ventilated room). Do you smoke where your tank room is? there are diff methods depending on weather you want a quickie raise or are you trying to hold it consistent. [eidt]Oh and pls don't try to buffer further as your alk is the top end. Any further alk increase can bring your tank and its contents to a dangerous level. In fact at 11.2, I'm most uncomfortable for you. I'll leave everything as it is until it drops back to about dKH 8. Best Quote Link to comment Share on other sites More sharing options...

SRC Member madmac Posted June 29, 2006 SRC Member Share Posted June 29, 2006 my nitrate is quite high thou at 50 plus oh dear, what a mess. Don't confused yourself further with Ca now. A consistently low pH is almost always because of two things : a dirty tank or excess CO2 You've already correctly stated the reason for the low pH,... quoted above. Clean up your NO3, bring it down to as low as possible, and you will see your pH improve. 50 is way above limit. Care to list your tank parameters. It may be possible that the salt you're using is causing this. If your SG is high, replace some water with clean fresh water by syphoning out as much dirt as possible.

jervismun Posted June 29, 2006 Share Posted June 29, 2006 Bro I suggest you invest in a more efficient protein skimmer... got a feeling you have too much things rotting/decaying in your tank... so no matter how much water you change... your NO3 will still remain high Quote Tank 60x40x40 Optiwhite Glass Tank Sump Elos 500 w/ Tunze Overflow Protein Skimmer Skimz Kone SK1 Return Pump Hydor Seltz L30 Wavemaker Hydor K1 Illumination 150W + 2 T5 Chiller Arctica 1/5hp w/ Aquabee 1000 Water Top-up Tunze Osmolator Dosing Pumps Grotech 3-Channels Calcium Reactor Deltec PF 501 Computer Aquatronica Link to comment Share on other sites More sharing options...
jervismun Posted June 29, 2006 Share Posted June 29, 2006 my skimmer not skimming now cuz i acc turned the valve yesterday, i thinking restarting again Bro seriously... this shows your skimmer is not working... a good skimmer can take away a lot of problems before they even turn into problems IMO 60+ NO3 is unacceptable. Sorry bro for the blunt words... but I think we shouldn't be political and beatin' round the bush... you need to do it step by step and getting a good skimmer could as well be your first step.
