Hey. I was watching your video where you talk about allelopathy and how it affects other organisms including bacteria, mosquito larvae, and other plants. Can Allelopathy affect fish fry and eggs? Because there are some people that can never get certain fish species' eggs or fry to develop to adulthood and eggs and fry are fragile and would be more vulnerable to chemicals in the water.

Great videos Joe! Really enjoyed your synopsis of the walstad method! I'm starting a 55g hex dirt build. I'll be blogging it in hopes of helpful feedback on this great site! Thanks again !!

Hi again Joe. I have my substrate materials now and am going to do the substrate when I have the time here soon. I've been thinking about the plants we like and which ones to start with. I was wondering how floating plants (or plants that can be floated), handle the higher ammonia and nitrate levels of newly dirted tank.

I was thinking of floating some Hygrophila difformis to compete w/ algae for light and waterbound nutrients. Also considering Ludwigia repens, Anubias nana, and either Micrathemum micranthemoides or hemianthus callitrichoides as a carpet-start.

That is what I'm thinking for starter plants. Wondering if it is enough plants, and if the difformis will get burned or melt if I float it. Any thoughts?
