'Good' meaning a reliable brand and product, or good as in 'healthy for my fish to use artificial chemicals'?

Tanks: 40 gal FW setup, 10 gal Reef tank.

good in that it would lower my ph, and keep it stable, i dont like harming fish with chemicals but a lower ph would be ideal.

Thing is, your standard source of water (your tap, I assume), set your pH at 8.0 - 8.2 by default since that is the pH of your source. This means that, whatever you do to lower it now, you will have to do every week, with EVERY water change. Your fish will need to endure this pH fluctuation often (depending on how often you change your water), which is not good for them.

ok my tap water is high because i used hard water, from a well. I dont want to constantly keep adding chemicals to the water but i just want my ph to be like 6.8 because all the fish i want thrive in that ph. the fish i am interested in are: angels, balas dwarf gouramis, zebra danios, rummy nose tetra and clown loaches. so i just thought it would be better for my fish, but i am not sure if they will live for a long time and not be stressed in waters with ph of 8.0.

I agree.

Lowering/increasing Ph can be done but it requires a lot of very careful monitoring. You can reduce fluctuations by monitoring very carefully and always adding whateer you're adding whenever it increases again, but fluctuations will still happen and that's very bad for fish. Generally the best idea is to find fish that like the water parameters as they are, as I found out the hard way when I lost a molly due to my water being far too soft for her.

The only way you could stop this is by using bottled water but like Kate said you'd have to test loads of different brands to find out their Ph value. I don't know but I'm not sure all bottles of Evian for example would be exactly the same either. There are added vitamins and minerals in bottles water - you'd have to check out how they would affect your fish as well. I remember a post here one time advising against bottles water for tanks because of the added vitamins and minerals being bad for the fish.

ok so if i dont add chemicals, and i keep my ph the same will the fish i want live good in that kind of ph? I know that freshwater fish that like high ph are chiclids but i dont want chichlids, i want a tank that is based around angels. so do you think they would lead a good life in waters with a ph of 8.0?

Angels can tolerate a wide range. Up to 8.5, iirc.

Tanks: 40 gal FW setup, 10 gal Reef tank.

Angels are cichlids BTW

I'm not saying that to be picky, I'm just saying it because I don't know what your reasons for not wanting cichlids are. A lot of people don't like them because they're nippy or agressive, so just letting you know...

i just dont want chichlids because i have a planted tank and i like other fish other than chichlids, and yes i know that angels are chichlids, but i was hoping to breed the angels but alot of sites say that they like water around 6.8 not lik8.0-8.2
