How can I raise the water hardness in my tank? :wl:

Hi Aquaboy,
I've just noticed this and unfortunately it is my bed time, but here is a <a href='http://z13.invisionfree.com/AllFishForums/index.php?showtopic=1106' target='_blank'>link</a> to some intensive info, hope it helps for now. A quick answer: add calcium in the form of or combinations of limestone, coral sand, crushed coral, tufa rock and crushed seashell directly to your tank or placed in your filter. :tup:

pH can be lowered by using bogwood, Indian almond leaves, or by filtering through peat - the last being the most effective way.

Seashells can also be added to filters to reduce the pH if you do not want them "in" your tank as such...

I didn't mean pH, I meant dGH. For my pH I use Correct pH tablets by Jungle. Hey, do you need any fish or supplies or know anybody who does, because I really, really need to sell all this stuff to buy a new tank. I changed my mind about the 30 gallon. I'm gonna go with a 55 gallon. :60:

Eeeb! Try not to use "correction" chemicals - these can cause serious fluctuations. Natural is best IMO.

As you've probably seen, we do have a trade centre here - and eBay is often worth a shot, as people will collect.

I've heard that driftwood keeps the pH about right, is this true?

As Kat says, bogwood does indeed help :)

You could also filter your water through some peat before doing waterchanges.

Well, I think I'll just stick with the stuff I have, because every time I've taken my water to PETsMART, My pH has been between 6.8 and 7.2, which is what the Correct pH is supposed to keep it.

The chemicals are not very stable they will change your chemistry Very quickly, and your 6.8-7.2 is 40 times more alkali/acidic than each other. You can also pick up a pH test up pretty cheap these days saving taking it to the FS every day. I recomend the tetra laborette, it has pH, GH, KH and nitrite tests.
whats your raw tapwaters pH?

I have no clue what my tap pH is. I did see this stuff online called Proper pH. Its supposed to keep the pH at precisely 7.0 Its made by Aquarium Pharmaceutics, which is a brand I trust very much. Every thing I've gotten from them works perfectly! One customer gave it a review and said it keeps the pH just where its supposed to. ^_^

Hrmmm. As SD says, I don't agree with using chems to adjust water.

Test your tap water - you may be surprised.

Sodium bicarbonate (sold as baking soda) can raise pH gently to about 8.2 and is safe for fish that like that sort of pH.

Magnesium sulfate (sold as Epsom salts) can be used safely to increase GH without raising the pH.

Calcium chloride dihydrate or hexahydrate can be used when calcium ions are needed.
Need to get these one from specialist chem companies but are still very cheap.

Its a very old, tried and trusted for Malawis and Tang cichlids and its practically free.
There is nothing un natural about this. These are the ions in natural hard alkali water.

I do not like adding none buffered water to tanks with limestone or coral etc in them as "your pH risers" as you get small but unpleasant pH swings the calcium carbonate in them takes too long to dissolve and buffer the water.

Read the make up on commercial pH up or pH 7.5 and above stable products you will find most just have these in them. :)

Aquarium pH tests are awful I think. Hopeless at picking up pH changes as the colors never match the cards.
I use a Hanna pH checker. cost £29 just dip and read didgital figure displayed, reads pH from 1-14 accurate to pH 0.1+or minus 0.02 (reads to 0.01 but ignor the last didget you do not need it nor is this bit that precise) and it lasts at least 5 years.
