Whats the best natural way to raise ph up in your shrimp tank?

my tank with ADA aqua Soil is currently sitting at 6.0...

would like it near 6.6 or so..

How thick is your soil? Are you using RO water?

I'd say roughly 5-6cm height.... and just rain water?

Rain water is acidic to start with. A thick layer of Ada soil will also lower ph. If you don't want to use RO water then you can mix rain water and tap water ( make sure you remove the chlorine). Tap water is around ph 7.6 ish and rainwater would be in the near 6 ( I'm guessing). You can also reduce the thickness of your soil to reduce the buffering. I think it's your rain water that is keeping your ph at 6

Why raise it ? What shrimps are you planning to put in there ? I have my CRS in PH 5.2-7...and all great.

That totally depends on where you are and where your tap water comes from....tap water should sit around 7 though.

I don't know what you concider "natural" but the easiest way to rise your pH is Bicarb of soda (Baking Soda). From memory a rule of thumb is 3 g in 100 L (roughly 1 Teaspoon) raises the KH by 1 and that will raise your pH as well.

Depending on the size of your tank it is the easiest to make a solution of 1 Teaspoon of bicarb in 1 Liter of rain water. Then add some of the solution (measure the amount you are using) gradually to your tank over the next couple of days until you get to your desired pH.

And that is probably the much better advice! Just leave it alone! :)

@garnelchen, adding baking soda isn't the natural way. I'm just answering the question what kunzy had ask.

hmm thanks for all the ideas... what do you guys think, rainwater? or tap water d-chorlinced? im keeping snow whites in a 3 ft tank? whats best for them and why?

i always thought rain water "its natural" sorta thing LOL:D

i will be adding salty shrimp to all my water from next week.

SW at PH 6 is perfect. Buying buffering soil, and then trying to raise it, is counter-active. The SW will be perfectly fine at that PH, and over 6 month -2 years, the PH will slowly rise...once it gets above 7, then the question will be, how to lower PH, which tends to be the common question with us shrimp keepers.

Thanks for your help BB!

What do you think is better? Rain water or normal tap water? any helpers :D

That depends on the parameters of your tapwater!

@garnelchen' date=' adding baking soda isn't the natural way. I'm just answering the question what kunzy had ask.[/quote']

There is no such thing as natural and un-natural...if you want to raise the pH, you need to raise the KH and to do that you need to add carbonate.

Whether you achive that by using snail shell or rocks or NaHCO3 does not make any difference....other than that baking soda will not affect your GH.

NaHCO3 does occur as a natural mineral called nahcolite....or as the white stuff called baking powder in supermarkets. Same difference ;)

Rain water is acidic to start with.

Wait a minute. Rain water should be neutral 7.0.

Acid rain might have a pH lower than 7.0 due to pollutants - hence the name acid rain.

However' date=' we are lucky enough to live in a country that isn't too polluted to have acid rain, doesn't mean it can't happen. Just the likelihood of it occurring is lower.

Rain water is however low in GH & KH, making it "soft water" due to a lack in buffering capabilities.

It is this soft water nature lacking in buffers that allows the pH in rain water to drop easily in an aquarium due to other factors like nitrification process, peat filter material, drift wood, etc. Creating the illusion that rain water is acidic. It's not, it's right on neutral and it doesn't take much to tip it over to either acidic or alkaline.

On another note about adding carbonates ... To raise both GH, add magnesium sulfate (MgS04) or more common know as Epsom Salts. It's used as fertiliser, so your plants will enjoy it.

Bicarb/baking soda will raise the pH temporarily, but pH will fall again if your water isn't buffered. MgS04/ Epsom Salts will buffer it a bit more since it also raises GH.

I'm not saying Kunzy needs to add anything, since 6.0 is perfect for the shrimp he is keeping. Just another method of raising pH.

Reducing pH is a bit more complex as we all know.

Just a note on this, make sure you use baking SODA or bi-carb soda, baking POWDER is different and has other things added, like rice flour :)

... To raise both GH and KH simultaneously' date=' add calcium carbonate (CaCO3) or more common know as Epsom Salts. It's used as fertiliser, so your plants will enjoy it. The calcium is good for shrimps.[/quote']

Epsom salts is magnesium sulfate (MgS04), not CaC03. It does raise GH by increasing Mg. Using Epsom Salt to raise GH will alter the Ca:Mg ratio....ideally @ 3:1 to 4:1.

apologies, you're right.

I was fooling with calcium carbonate CaCO3 two days ago and had it on my mind.

Shouldnt rainwater be <7.0 as it reacts with the CO2 in the atmsphere forming a weak carbonic acid as it falls.

Pretty sure I read 6.2 the other day.

I just did a google search and Australian rainwater is below Ph 6. Any thing under ph 5 would be consider acid rain. This is from CSIRO Australia.

Natural distilled water with nothing but dissolved atmospheric CO2 is pH5.8, always.

It's when there are Sulfides and NOx in the air that you get acid rain.

Rainwater in a non polluted area is always 5.8, rainwater in the city is likely to be closer to 5.

Ok, i have to clarify something in this thread.

NaHCO3 is an effective method of bringing pH up, it increases the KH (Magnesium Sulfate does not), but not the GH. GH is increased by CaCO3, which is slower to dissolve, which also increases KH.

HCO3- is an effective buffering ion, not sure where the idea of it being temporary comes from, it is a very important buffer, namely the one that keeps you alive and prevents your bones from decaying inside your body.

It works by countering pH changes (to a degree, i won't explain the equilibrium constants), i.e either becoming protonated in an acid or becoming deprotonated in basic solutions (again simplified). It works better at buffering acidic water up than basic water down (this is due to the equilibrium constants and pka1 and pka2, trust me on this)

Im getting closer :) the other day you corrected my guess at high 6's to 5.8 and todays guess was 6.2 maybe next time someone asks I might be able to remember 5.8 lol

      It must have been an aluminium heatsink. The Indium in Liquid metal will eat through aluminium. Only copper or nickel plated heatsinks can be used with liquid metal. It says so on the packet, at least my pack of Thermal Grizzly Conductonaut does.

      I will try to add all the old tank's shrimps at the end of August to the new tank, had a problem with my chiller this morning, try to make it more efficient by adding a better heat sink grease, I added a liquid metal grease, apparently you can't add liquid metal, when heating up, the heat sink turning to dust, along with part of the cooler inlet and outlet. So far the shrimps are ok.

      I have had the new shrimps a week and have ordered some new ones(10) for delivery friday. There are probably at least 6 of the 8 alive (they may even all be alive still) but as the tank is so densely planted it is difficult to tell, but I saw 2 black and 2 red this morning, as yesterday, but I'm sure 1 red and  1 black weren't the same as the ones I saw yesterday so there are probably at least 6, if that makes any sense??? Anyway that will be it for now and I will just let the tank and shrimps do there thing once this batch are in there in a couple of days, and I can get back to the usual routine as was, before this unfortunate event wiped out the last lot. All parameters are good, including the nitrates now, but there are a lot of brown patches on the plants and moss balls still......... It all looks a bit drab and uninspiring and brown!!! I probably just need to be a bit more patient? I will do some maintenance tomorrow and a small 2L water change, then the new shrimps will go in on friday after acclimatising. The shrimps were totally uninterested in the spinach or shrimp lolly I put in at the weekend but I am assuming they have so much biofilm at this stage that that is keeping them busy and well fed and they are staying under cover until they get used to their new environment and this strange ugly monster that keeps peering in at them through the glass from time to time? I guess if some 100ft tall bloke kept peering through my window a few times a day I would be a bit nervous/reserved shall we say? I removed the spinach and the shrimp lolly and put the shrimp lolly in the betta tank and within minutes there were 10 shrimp on it so there was definitely nothing wrong with that shrimp lolly!

      Traps don't work on hydra. Even with planaria, it is slow and it doesn't catch them all.
