Aquatic compost has some goodness added in but not enough to cause an algal bloom, but this 'special loam' is expensive. I do what mark does use normal pots with slits in and low fertile soil from the garden where something big has grown which has soaked up all the nutrients. Here's how i pot up a marginal plant; fill the bottom with fine gravel about 1/4 of the pot then a 1/4 of soil or aquatic compost so the plant gets a boost when you first pot up, put your plant in making sure the base of the plant is just under the rim of the pot, if it isn't you need a bigger pot, then half way up the root ball fill again with soil or compost and after that the rest i fill with gravel right up to the top of the plant, this way the pot is heavy and wont fall over and the fish wont be interested in tampering with the soil
