help with ph
 
i was reading the city water report today and the ph is 7.8, my test kit wont even read that high it only goes to 7.6

do i need to lower my ph for my bettas and kuhli loaches? so far they seem to be doing okay but still.

Probably not, but the hardness is just as important, and as this is related to pH it would be good to find out what your GH (general hardness) and KH (carbonate hardness or alkalinity) is for the tap water. The pH will tend to lower in an established aquarium, but this is buffered to some degree by the hardness. You can or should be able to get the GH and KH/Alkalinity from your water supply people. When you have those numbers, post them and we can discuss.

Also, you might find this article helpful in understanding the relationship:

hardness is roughly 170 mg/L and alkalinity is roughly 125- 130 mg/L

The GH is not bad, generally speaking it is medium hard at around 9 dGH. The KH is around 7 d, and that is likely going to buffer the pH enough to keep it where it is even in the established tank. For the fish mentioned, I would leave it.

Some other species might/would need this lowered, just so you know. In your case, this would be easily achieved by diluting the tap water with "pure" water or even rainwater.

thank you for the information.

my next tank (this is going to take forever to set up piece by piece on each pay cheque lol) is going to be a 50 gallon planted tank with 2 filters. possibly fluval 305s.

for stock i want 6 tiger danios, 20 neon tetras, 5 kuhli loaches, 10 or 15 ghost or cherry red shrimp, 10 golden barbs and 10 cherry barbs.

im still in the research stages of this project but here is as good a place as any to ask questions. would i need to change my water parameters for these fish?

Would advise against changing pH,hardness level's without fair knowledge of what/how products that do this, work.
Of the fishes you mention,, only the neon's would appreciate a bit softer GH ,the other's,,would be fine.
I would not place the number's of fish you mention, 40 +,, in 50 gallon tank and would maybe forego the neon's which in my view,,are not at all,, the hardy fish they used to be year's ago.
If you are set on the neon's,, I might see if fish store would hold these fish for you, with perhaps small deposit for a couple weeks, and if they are still fairing well in dealer's tank after this length of time, then perhaps they will adapt to your water if it is close to same as that in dealer's tank.
The barb's,khulii's, danios,and shrimp, would be fine in my opinion without any altering of water.
