PH lowering liquid
My tap comes out at around 7.8 PH which is too high for my three tanks. I keep them at 6.6, 6.8 and 7. I was using the tiny bottle of PH down from an API kit but its expensive and I change a lot of water between the three tanks. I found this stuff and a local hydro store, can I use it? I assume since it just alters the PH and doesnt have any other stuff in it, it should be fine? Let me know what you think. Heres the link

It would seam this is meant for soil, and not water based applications. It's designed for lowering the pH of the nutrients found in soil.
If you look on page 7 of the manufacturer's MSDS sheet, you will even see the EPA as one of the components (Phosphoric acid) listed as a pollutant within the Clean Water Act (CWA) 311
I got all this info from the link you postedIf you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

any idea what the active ingredient in the API stuff is?

No, see if you can find the MSDS, those generally have a lot of useful information.
Phosphoric acid in itself is not necessarily bad but you're running a big risk of a blue algae problem if you'd use that.
If you want proper advice I'd advice you to share some more information like what you are keeping, what the decor is and, if you happen to know, any hardness information about your tapwater. Good chance there's alternatives which are going to turn out cheaper and which your fish will appreciate more.

40 gal breeder 6 Dojo Loaches Looking to add Hillstreams and Blue neon Gobys.

all with a lot of Java moss and Java Fern. Not sure on the hardness.

I'm almost clueless on African species so no help there.
The dojo tank would indeed benefit from a ph that's a touch lower but your tap isn't necessarily bad for them.
On the 39.. I'm not entirely sure about the frog but all of the fish in there will not mind at all if you get a chunk of wood in there and 2-3 indian almond leafs. Thing is, could you life with tannin stained water?
Another way of thinking... how much have you spend on that pH down last year? And how much will a simple reverse osmosis device cost?

I agree with talldutchie on the dojo tank. The other tanks mates would be ok as well. 7.8 is pushing it, but it's no where near as bad as it would be for other species. All those come from faster flowing waters with more stone and minerals in the water than dissolved organic material. So that environment tends to have a slightly higher ph value than most tropical environments.Increasing your biodiversity increases your stability.
You know what this tank needs? ........................ Crypts.

Well I have been using the API PH down stuff for a long time now but being in colorado and having just had a major flood nearby everyones PHs has spiked. Mine used to come out of the tap at 6.8 pretty much perfect. So to be clear I have always maintained the correct PH for each tank regardless of how high the tap was originally. After the flood though Ive been having to use much much much more PH down to get it to the correct levels. I think reverse osmosis would probably be worth looking into. Ive just been burning through the tiny API PH down bottles because weekly water changes to maintain about 130 gallons of water uses alot. The community tank does have driftwood so it does have some minor tannins that are less intense as time passes. the Dojo tank has a powerhead and alot of bubblers for dissolved oxy.

PH down is also very unpredictable as its acid can take some time to completely neutralize and the PH will swing back up a bit. Ph down simply eats away at the waters buffering ability against PH swings buy lowing the waters KH. I think maybe it would be safer to mix RO water with your tap water and bring the KH down to no lower then 2-3 giving you a PH in the 7.4ish range.
OR, you can run water with a kh of 5-6 giving you a PH in the 7.7-7.8 range and lower it with pressurized Co2 to 6.6-6.7, much safer. Also PH swings caused by Co2 injection do not effect livestock in the same way as low carbonate hardness movements. Most tetras are tank raised anyway and used to higher ph. It's really water chemistry stability that matters most not obtaining the perfect numbers from the wild. Your not trying to breed them, just keep them right?
