nw1411 Posted May 16, 2004 Share Posted May 16, 2004 G'day Guys, This morning I noticed that the pH in one of my tanks had dropped quite a bit overnight. Nothing had been done to cause this. Question. What do you guys use to keep pH up? I know there are various buffers and your 'pH up' powders. What is the best way that you have found?

Mbuna Posted May 16, 2004 Share Posted May 16, 2004 the best way to get a constant high ph is to use buffers like shell grit or coral sand in your tank. to get a better effect you can put them in your filters. Link to comment Share on other sites More sharing options...
Chester Posted May 17, 2004 Share Posted May 17, 2004 If you want to keep your pH up then it is best to remove any driftwood from your tank and to try use a buffer such as substrate or to add something like chipped marble, coral sand or shell grit to your filter.

nw1411 Posted May 17, 2004 Author Share Posted May 17, 2004 Can I get Coral Sand etc from a LFS? Tank= 48x18x18 How much coral sand / Shell Grit is required? Thanks Nath Link to comment Share on other sites More sharing options...
Chester Posted May 17, 2004 Share Posted May 17, 2004 You can get coral sand from the LFS but it is really expensive. If I were you I would choose chipped marble. Coral Sand is about $15 for 5kgs. Chipped Marble is about $10 for 20kgs. Link to comment Share on other sites More sharing options...
r.d.m Posted May 17, 2004 Share Posted May 17, 2004 ph will change ,at the end of the day when the plants(algae)have been actively photosynthesising all day it will be high ,first thing in the morning it will always be lower .ihave found that sydney water even though it has a ph of 7.5 is very soft and in an african tank you will always battle ph,shell grit helps but ive found that aquasonic rift valley conditioner will keep the ph around 8.2-8.4 but more importantly increase the hardness significantly-around 18 gh and i think this stabilizes the ph good luck oh and by the way next time your at the beach on a sunny day take your ph kit with you and find arockpool with lots of algae ph readings of 10-12 are common.

PHL Posted May 17, 2004 Share Posted May 17, 2004 Personally I just use oyster grit in the canister filter for those I want to buffer the pH around 7.5. They are cheap, and effective; the more acidic, the more they dissolve and buffer. Link to comment Share on other sites More sharing options...
