I have a 90g with gymno's and some other friends. My parameters are pretty much perfect or as good as they can get: amm-0, nitrates-0, nitrites-0, phos-0. But my pH is around 6.0 during the morning and 5.7 during the day. I know lighting has an effect on it. My hardness is around 6 dkH. Any ideas on how to increase my pH? I am not a fan of dosing anything over long periods of time. In fact, I dont like adding anything to my water if not necessary. I am adding driftwood this week as well as several bunches of Java fern.

Dw lowers it. Just keep it stable and no lighting does NOT effect ph!

I wouldn't think that would cause a problem for the fish you're keeping, AFAIK clowns, blazanii and bristlenose all prefer water on the softer side of neutral. If you're worried about it dropping too low you could add a few pieces of coral or crushed shell to your sump/filter.

I was considering adding some coral to my filtration. I was just unsure as to any proven long term effects. I have yet to find any real problems. I have a ph monitor in my tank along side my temp probe and it worries me to watch it drop so low. But, like I said, I have yet to find anything. I may just leave it be, as nothing is broke, so to speak. Thanks Dave for the reply too!!

Thanks for the info. However, I disagree about the lighting and its effects on pH. It is very well known in the saltwater realm that light duration, colr, and intensity absolutely does have an effect on ph. In regards to fresh water, I am not sure. Thats what I was trying to figure ouot. I will as I begin to grapg my lighting periods alongside my pH readings. here is a quick link to another graph that was kept in salt.
 
Carbonic acid is produced by excess waste in your tank. This acidifies the fishes' environment, lowering its pH. Setting up your aquarium in direct sunlight, or leaving the hood light on too long promotes excessive algae growth, and raises the pH in your aquarium. When algae grows, visible or not, it will increase the ph's response to the carbonic acid being produced by the change in algae growth.
