High Ph problem
The PH for my tap is around 8.2-8.4 . Is there an inexpensive way to lower this. The chemicals I use for my weekly water changes are getting kind of expensive.

Did you test your tap water after it had sat out for 24 hours or right form the tap? It can change quit a bit.

As for ways to lower it naturally, driftwood is a good way and filtering the water over peat moss are easy choices.

Re: High Ph problem
a stable pH is far better for fish than one that is in continual flux.
most fish will readily adapt to a higher pH than is found in their natural environment. Chances are if you have a high pH coming out of your tap, so does your LFS and the fish should already be accustomed to it.

your pH is ideal for African rift lake cichlids (malawis, tanganikans and victorians) maybe you could look into the challenge of keeping them.

if you really don't want to try cichlids and have to lower your pH
then as fish-4-all has stated, peat filtration is a good way to go.
however peat looses its ability to alter the pH as the tanic acids are used, so every 6-8 weeks it needs replacing.
a more permanent solution to your problem could be performing a 50% water change using RO water (invest in a RO unit or buy per/ltr from lfs)
then every water change use 50/50 RO/tapwater.
it is good pratice that one every 3rd or 4th water change you use full tap water to put back essential base elements the fish need.

if the above advise on RO seems a bit confusing, say so and I'll try and explain it in easy steps for you.

Well I dwarf puffers and the ideal for them is 7.0 Would the 8.2 be O.K for them?

according to fishbase (the Swedish institute of ichthyology)
Carinotetraodon travancoricus has a pH range of 7.5 8.3
so yes it should be ok

No offense Wolf but it also says they are in the high price range and an endangered species. Are you sure the pH part is accurate?

The-Wolf 02-28-2008 11:07 AM

no offence but if you read it properly you'll see it says
price category: very high; price reliability: very questionable

ok sorry didn't really get that part. I just want to make sure the info I get is accurate. This IS the internet lol.
