Last week I dosed a fair amount of Sodium Silicate, for the sponges. I've also been adding Phytoplankton for them. I kind of expected an uptick in Diatoms, but no. There is a large bag of Silica sand already in the sand bed, so I guess there was already a good baseline of silicates in the water. My hope is to give the sponges an added food source, as well as their building blocks for growth.
Today I dosed Ammonia, followed by Phytoplankton, which is maybe a dangerous combination. I could end up with pea soup! I'm kinda curious if I could. It would be cool to maintain a manageable, sustainable population of Phytoplankton - without the pea soup.
When I cleaned up my canister filter I moved the location of the return outlet hose to just over the wave box. This strengthens the current a bit, which is nice, plus I'm directing all that CO2 laden water directly to the plants that need it.
Today I gave a the grasses a haircut. So now they're all about the same height. I'm curious to see how they grow back, with the renewed dosing of Ammonia and CO2. It's an experiment. Ideally, they'll all grow tall together, but I suspect they'll come back unevenly. We shall see.
The mangroves have both lost their growth tip leaves, so that could be the last of them. Kind of a bummer, but not too big a deal. I'll leave them in and see if they bounce back. Adding them was kind of an impulse buy/experiment. What did I learn? Planting them submerged in a 30 inch deep tank may have been a bridge too far. I wonder if I had kept CO2 running without a lapse, would they have made it? I think the ideal setup would be to have them planted in rich soil, but with the growth tips above water. If I tried them again, maybe I could fashion a way to mount them emergent, without it being too hideous. That would encourage prop roots to grow. With mine already in good dirt, they didn't seem to need any. I'll file away this experience to use another day, perhaps.
Today I plan to get the QTs up and running. I've gotten permission form the 'Boss' to set up the larger QT as well, so I can accommodate a harem, heh heh.
