    I think I may have a flow/circulation problem and really not sure what to do. As you know I od'd my tank with alk...I have been allowing it to fall on its own (after w/c's)...the alk just really wasn't/isn't coming down. The water in the sump falls into a sock, so its got air being introduced...

    I am toying with the idea of dosing my tank with Epsoms Salt to bring the Mg. up to around 1400, my question is will this have an effect on my salinity? My parameters as of right now are: Cal. 465 Alk. 4 meg/l Mg. 1250 I test with Seachem test kits and will change to Salifert next time I...

    My PH is always up high. 8.8 usually. (Source is like 7.8 ???) Should I be trying to lower this? I add calcium, purple up sometimes, but no PH/ALK buffer of any kind. These typically raise PH or ALK, don't they? My ALK is usually high too. About 9-10 range now. Was staying at about 11-11.5...

    :idea: what is the best salinity for sps I did a water change last night and it went from 35.5 to 36.0 or 1.0265 is this to high?

    Is there a list of all the acronyms that people use on the reef sites? HOB = Hang on Back MH = Metal Halid ect .... i am such dummy when it comes to these things

    When you do a "H2O only" topoff......what ~8.3pH buffer product do you use to treat the water PRIOR to pouring the water in the tank?
  9. General Reef Discussion
    I recently ran my skimmer intake hose outside to help raise my pH since it is located in the basement. It helped a bit and I also realized that my auto top-off water couldn't be helping my less than 8.3 pH situation. I have been topping off with < 7 pH water with little or no buffers in it. I...

    My alkalinity is at 5.04 dkh or 1.8 meq/l from 2 sources mine (hagen) and a local lfs (salifert). Is this level dangerous for the inhabitants. Should i be making a big change or can I raise it gradually? I was thinking of baking soda. My math puts me at 32 g baked sodium bicarbonate will...

    Seems like everytime i do a water change with my top off water (distilled) it effects my alkalinity, should i buffer my top off water to get it to a good alk, i think the top off is 80mg/l but my tank water is like 200-300mg/l i think or meg/l or whatever just wondered if anyone else does...

    Yup thats right.. it is time to roll up those sleves and dust of the brain.. Chemistry 101 Lets start off with the the very basic Reef chemistry. , then move in to the more heavier things including making your own kalk... So tell me what your parameters...

    My PH level is continually low. Does anyone know if it's ok to use pool/hot tub PH adjusters in an aquarium. Is there any difference between PH chems used in pools and tanks?

    hi Ive spent the last couple hours reading through post trying to figure out what to do so i figured i would just ask. I have a 55 salt with about three 5gal buckets of live rock in it,25lbs of sand 25 lbs of crushed coral,(the sand and crushed coral are all mixed up do to the engieneer...

    I just recently noticed that my ph level in my tank has been getting lower Alot lower.It started out about 8.0 and then it was getting worse and worse.I thought that i would correct this and try to stableize my ph by doing some water changes.It got worse,my corals were suffering.Today i thought...

    hello everyone. had a quick question. i have a bunch of 50 mM calcium cloride in my lab that i dont need any more. can that be used in our tanks? i have over 4 liters sterile, hate to just toss it

    I'm setting up a 90 gal sw reef and am in the cycling portion of the setup. I was doing some testing and noticed that the gh was 2000ppm and the kh was 170 Can anyone tell me what the proper levels should be? also in reading my Hagen test kit info for Calcium it shows some equations for...

    I've got a 50g fish and reef tank. Two clowns two dwarf angels and a couple shrimp, 50 lbs live rock and a half dozen corals, mushrooms and leathers easy stuff. Problem is ph drops to about 7.4 unless i put some buffer in weekly. Is this a problem?

    Hi, I'm having trouble keeping my Alk up. I use kalk in my top off water, ALMOST all the time. But if I miss a day or 2, my Alk goes down to about 7. My guess is I just need to use more kalk more often. But my stupid question is, What uses up the Alk?

    I got this toadstool on friday and until today everything looked great with it. Today it has this white area on it as seen in the picture. Can anyone tell what is wrong plus it seems to be shrinking in height. Is there anyway to save it? Thanks in Advance Salinity - .023 <ACRONYM...
