hello all. i have 2 tanks (10g and 29g)
i used di water for both.
both contain similar plants that i've been steadily dosing with flourish excel for about a week now.
tap water is 6.8 ph according to aquarium pharmaceuticals test.
the 10g has a mixture of red flourite and pet store bought gravel, and a piece of well boiled driftwood. it has a ph of 7.
the 29g contains 3 bags of eco-complete including the packing water from all 3 bags. it is showing me a ph of 7.6.
is eco-complete known to do this? i searched the forums here and found one post that sorta casually mentions this, but in no detail. is it supposed to raise the ph this much or could it be something else? both tanks have been set up for less than a week. some of the plants have been in there less than a day.
my plan was to get some plants that would grow in my medium wpg lighting situation and have some schools of tetras with cories. does this 7.6 ph in the 29g tank preclude any chance of cardinals and neons which the charts say require a ph of 5-6? i realize that the fish could probably go higher on the ph meter, but i want them to be happy.
i read the interview with the carib sea rep that was posted somewhere on this forum. he said the liquid in eco complete will keep a floor on ph. but does anyone know what he's referring to? maybe changing water over time will eliminate whatever it is that is raising my ph so high. if it's actually the substrate, then i guess i will have to modify my water somehow. just when i thought my nyc soft, slightly acidic tap water would be perfect for tetras.
