Best Way To Lower Ph In Tank Water?

Hi. I was wanting to have a tank dedicated to different tetra and Otto’s but my PH is 7.8 and I read that tetra like PH 6.5 and Otto’s PH 7.0. Is there a cost effective way of me to lower my PH? Or will they be ok in this tank? All other water parameters are perfect and it is a 70 litre tank.

Many thanks

 

The tetras can get use to that ph I have them in 7.6ph and they are doing good I'm not sure about the otto the main thing is there are no to little fluctuations in the ph

 

Almond leafs, wood and some substrates will and can lover your pH, don't use chemicals to lower it beacuose it is easy to crash your system. If you add leafs and wood you will be probably closer to 7ph and fish will be fine. Constant water parameters are best for fish.

Thanks appcontrol. I was thinking of getting some driftwood which I hope will help the PH.

Thanks again grump299 lol. I have heard Otto’s are difficult to adapt but once settled are quite hardy

And it would be good for ottos you have some algae in new tank.. I hope it will

Ottos are sensitive I had best luck with drip acclimation system on them I usually just acclimate for temparature. You need some algae get few smooth rocks get them in some water and leave light over them for 24-48 hours so they have some biofilm and algae on start. Second fungus that you get on new driftwood they love it. Don't feed them tablets and things like that just give them enough surfaces for grazing an I usually give them on one rock som repashy supergreen once a month.

 

In San Antonio, water is well over 8 from the tap. I know almond leaves are recommended for lowering ph, but I’ve been thinking of trying oak leaves, of which I have tons , literally.
Thoughts and comments?

 

My tap water is very hard and alkaline, with the usual accompanying pH of 8.2. In the past I tried everything - lots of wood, leaves, peat. Didn't change it one iota. The harder your water is, the harder it is to change. A pH of 7.8 suggests your water isn't quite that resistant and may be worth a try, but nothing worked for me except an RO system. Still, there are plenty of fish who enjoy hard water. Most livebearers such as guppies, mollies and platies, African cichlids. I had a Bolivian ram that lived for 5 healthy years in it, though he was an exception. I could never keep neon tetras alive very long, but found Pristella Tetras are far more adaptable.

 

As mentioned, you'll need to know your KH first. If it's high, almost nothing will work, aside from RO or a buffered plant substrate. When people say certain fish need a low ph it really mostly means they need a lower KH.
