I have some of those bulbs sitting in water in a window right now. I'm glad I did not put them in the tank as suggested because they grew mold which is appearantly very common. It's been nearly a month and I will be contacting the company soon for replacements.
I ordered a marimo moss ball online and it should be arriving tomorrow. I have heard nothing but good things about the moss balls. I can't wait till I can put it in my tank and hopefully my boy will play with it!
I have a moss ball and I think they're great. I've had no problems with it what so ever. looks so cute too! ^.^
Don't know about the bulbs tho, never tried them. I don't really trust the idea of them being in the tank with my fish. However outside in the garden bulbs are great.
I bought a pack of 4 bulbs which actually contained 6. 3 of them grew, which isn't too bad. They can take a long time to start growing. The problem with the guarantee, at least on my pack, is they want you to mail them the bulbs that didn't grow and also pay for shipping for the new bulbs. Ends up costing as much as a new pack.
i can vouch for the bulbs causing fungus/mold. three sets, 3 different tanks. All got fungus/mold. It seems i have has the worst effects of the 3 tanks. The fungus/mold has spread to other parts of my tank in the span of a weekend. AVOID!
the moss balls are awesome, they look great and my betta loves moving them around. and depending on the size of it, they sometimes like to rest on it :)
