Should I do anything special for my planted tanks if I go on vacation for a week in the future? I have a 10 gal with frogbit and hornwort, and a 20 gal w/ anubias, hornwort, duckweed, frogbit, java moss and java fern. The tanks get Thrive and liquid CO2 twice a week. I'm guessing I should dose as usual them right before I leave. I do have timers for the lights. I feed my fish and shrimp before I leave, and they don't get anything while I am gone. Does this sound reasonable, or how can I assure my plants won't go downhill while I am away?
