I just found out that one of my co-workers is a aquarium hobbyists. He told me that the best way to lower the pH level of my tap water (pH 7.Cool is to use pure lemon juice. Do you think this is a good way to lower my pH levels?
My friend is giving me his 25 or 30-gallon tank and I want to have a lower pH level in it.

Why do you want to lower a 7.0 pH? That's a good pH to have, mostly, unless you are going for the more fragile freshwater, like altum angels.

There is no need to lower your pH.... most fish will do fine @ pH 7. The only reason to lower it would be for breeding, even sensitive fish like Discus will be fine @ pH 7.

Sorry I just read what I wrote and its suppose to be a pH level of 7.8 not "(pH 7.Cool "
LOL!

I want to breed my Honey Gouramis and maybe make my cardinal tetras feel more homey.

Sorry for the typo. Very Happy

So...
Do any of you think its a good idea to use lemon juice to lower the pH level of my tap water?

You can lower pH by adding acid (vinegar or muratic acid, never heard of lemon juice -- sorta sweet) but when you change water the pH will tend to bounce back toward the tap water levels. Your fish are likely to more appreciate fresh water than to care about the pH in particular. If you really want to lower the pH, try RO water in a mix with the tap water.

Mat,
Your Gouramis will probably do their business @ pH 7.8........ Your Cardinals are already acclimated so why put them through undue change & stress?

If you still want to lower your pH try peat filtration or mixing bottled drinking/spring water with your tap water..... check the parameters of the bottled water first. The brands I have used are slightly acidic & soft.

The problem with altering your pH is you will have to screw around with it every water change. Is it really worth it? Your fish will prefer a STABLE enviroment over one that may or may not be closer to their natural one. Their "natural" enviroment may very well be your LFS with the same water parameters as you!

I have used distilled water mixed with tap water to bring the pH and hardness down for some fish. Now I have a RO unit. For my wild caught fish that need very low pH and hardness I use RO water, then add some minerals (so the water isn't totally pure) then I filter it with peat. To keep the pH from bottoming out I add a pinch of lime (the stuff that's sold in gardening stores).

I would recommend looking into the conditions you need for your fish to spawn, and see if you still feel it's worth the work. They might spawn in the water that they're currently in. I've never tried to breed honey gouramis and cardinal tetras, so I'm not going there. Smile

To answer your question: No, I don't think it's a good idea to use lemon juice. There are better ways to lower pH without adding a mess of chemicals or citric acid in this case that could cause the pH bounce all over the place. I also have no idea how the fish would react to the oils and such, sounds scary.

The low pH is a side effect-- what softwater or blackwater fishes are responding to is low total dissolved solids (TDS). The lack of carbonates or phosphate in those waters, where tannins and humic acids are often more concentrated than calcium or magnesium ions, is what gives the low pH. Striving directly after the low pH puts the cart before the horse: it's the soft water you're really after.

Rainwater is cheaper than reverse osmosis. Have you seen the modern rainbarrels?

Yes, that would definitely work too. But if you have lotsa fish tanks and too small a yard for much besides a garden and a swing set (unless I cut those apple trees down), then RO's okay. Plus, there are those nifty little pumps, so you don't have to haul the water. Wink
