I would mix some Portland type 5 cement with concrete dye, sand, and some crushed gravel for texture, and apply it with a sponge. Portland type 5 is water proof so there should be no leaching.
My only issue with drylok is that I have seen it peel on concrete and block many times. I don't know how well it hold up to being immersed, not to mention pleco munching and fish scratching. Many people use it though so it should work.
