i have my gibba growing in a small aquarium 50/50 peat sand with sand on top. the plants were pushed into the soil. and have about 1.5 inchs of water above the soil. problem is. alge. i bought daphnia just as the problem started and was putting them in there. needless to say i only saw the alge get worse. the daphnia was never visiable for very long. i don't know if they died or if they got eaten. so, any tips on cleaning the tank? and or keeping it clean? today i even found one single mosquito larve in there... yuck!!
