Do phosphate buffers stimulate algal growth?
No. Phosphate buffers combine with essential trace elements, like iron, causing nutrient deficiencies. Proper pH 6.5, 7.0, and 7.5 should not be used in aquariums where algal growth is desirable.
Can I use Proper pH with aquarium plants?
No. Phosphate buffers will tie up essential trace elements and stunt plant growth.
