Does pH matter?
Thanx for the info, kush and all others.
We have really soft, high pH water out of the tap here. Even if i use that phosphate filled ph-Down stuff, the ph rises again anyway after a few days. I have never had my tank acid! I have spent some time investigating this phenomenon (the tendency for the pH to rise) and my current theory is that its being buffered to a higher pH by the water conditioner i use (these blue crystals, sold in australia by 'bates pets paradise'). Im still unsure though. i tried removing all the rocks in the tank, thikning they were affecting the pH, but it made no difference: the tank just tends to increase in pH. The 'pongol' im talking about is this stuff: Ophiopogon japonicus, which is also mondo grass. http://www.tropica.com/productcard.asp?id=159 and the dwarf variety http://www.tropica.com/productcard.asp?id=159A which makes it sound like a rather lame aquatic plant anyway. "Can be used as a decorative plant, but only lasts a few months." Bah! I'll sue the crap shop i got em from! n kush wrote: Nick L-S wrote ... the tank has an undergravel filter, which i hear isnt good for plants. Sure it is. Different plants will do better with or without a UGF, though. Deep root feeders like amazon swords and crypts do better without a UGF, most plants don't matter, and stem plants - plants which send roots out at the leaf nodes - seem to do better with a UGF. My question is, does pH matter? The water here has a naturally high pH... Yes, pH matters, but so many other factors affect pH that it's less important than a number of other things initially like, probably, gH and kH. As your tank becomes established the pH will tend downward. I use DIY CO2 and a lot of driftwood or bogwood in my heavily planted tanks so that, although the pH of my household water is about 8.0 out of the tap, the pH in my tanks is usually around 7.4. but if i try and use pH-down... This is a phosphate-based product. It may not lower your pH but it will give you SUCH an algae bloom! All the plants seem to be doing OK except for some long and dwarf pongol, do these plants need special treatment? Im currently not using any sort of fertilizer, but i am thinking i will.... I don't know that name. Do you have the Latin? |
