a couple tiny issues:
My underwater onion plant... no idea on the scientific name... is getting what I believe to be some algae growth on the leaves. it manifests as a dark green/brown fuzz... I can rub it off with my fingers, but it's definitely ugly. Takashi Amano I am not. Any ideas on what it is? feed less to get rid of it? I don't fertilize at all because I have fish and eco-complete to do it for me.
Speaking of eco-complete, when I do my water changes, i have not been vacuuming the substrate as i think it would stir it up and cloud my water for a while. I also don't want a huge buildup of detrius (sp?) in there, so it seems like im damned if I do and damned if I dont.
Next - in the absence of high powered lighting (only 20 watts for 29 gallons, right now) I've been opening the blinds in my office so the fish tank gets some natural light. it isn't direct light, but it's something. could this be the cause of my algae? Also, why is sunlight bad but false light is good?
My stats are still 0,0, and nitrAte 10ppm... after a full week. It's time for a water change according to my schedule, but don't the plants need around this much nitrAte to eat?
Finally - I think it would be cool to add some shrimp in there as little cleaners and something else fun to look at. Do they add a significant bio-load to the tank? My angels are still juveniles 1.5"-2" and i know the "if it fits in my mouth it's food" rule with them. Shrimp would fit in smaller pieces if bit apart though. Also - I have three yoyo loaches, which are just absolute gluttons, do these two species preclude me from having shrimp?
