Quick update--not much to talk about, short of the fact that I've finally placed my fish back into the system. They're thrilled. The tank is also finally clearing up, but is still somewhat hazy. The other good news is that the grasses are already sprouting! I was especially surprised to see the Thalassia already pushing out new shoots. One thing I did do for these, in particular, was to place small bits (~1/10th) of a plant fertilizer tablet at their bases. These tabs have some nitrogen, phosphorus, iron, as well as potassium, so it should give the Thalassia a good head start. The shoal and oar grass has sprouted some new shoots, as well. Pics to come when the tank clears and I get the opportunity.
