That 4lb of epsom salts was something like $1 at the grocery store. I've had it sitting around for a while and my wife was getting on my case because they were taking up room under her sink in the kitchen. She's happy now because I'm putting them to good use.
I mixed up my micro ferts last night. In a stroke of luck I found a syringe marked in mL in my junk box. In a stroke of genius I modified my fert bottles so I can dose macros and micros to four tanks in about two minutes. I punched a hole in the bottle cap and pulled a piece of airline through so about 1/2" is out of the bottle and the rest reaches down to the bottom. I drilled a small vent hole next to the air line and now I can suck fertilizers out of the bottle quickly and neatly. I'll post some pictures of it if I get home at a decent time tonight.
It might be my imagination, but I think the plants are growing really fast since I started with the ferts. I found a piece of what I'm assuming is rotala sitting on the glosso this morning that's about 5" long. I know it wasn't there Saturday when I did my PWCs and I don't think it escaped from the ground. I'm thinking it might the small piece (1/2") that I'd left floating because it was too short to plant. The water sprite is definitely growing and reaching up towards the light and the GSA on the glass is growing.
I'm sure the tank will get very full very fast. I'd like to see how these plants grow before I stuff more in. I've got my fingers crossed that I'll be trimming and replanting stems in a week or two. I did look at Petsmart for some telanthera rosefolia while I was waiting for my wife's Jeep to get aligned, but no dice.
I looked at your autodoser thread meegosh and several others. I'm not quite ready to try it yet. I've got four tanks with various light levels that I've started dosing as an experiment. I'd like to figure out a way to minimize the number of pumps I'd need. I know where there's an automatic watering system on clearance that could possibly be used as an autodoser for multiple tanks. It'd take some tuning though.
Predfan, don't hold your breath. Right now I've got a living room torn apart, two bathrooms in need of remodeling, and an entire house to landscape. For some reason my wife thinks the house rates higher on the priority list than my aquarium lights. The lighting effects might have to wait for my next LED
