I decided to wait for pictures, but I have a question for any planted gurus out there.
I'm going to be out of town this summer for a total of 12 weeks this summer, in two 6 week increments. I'm trying to plan ahead as far as fert dosing goes. I know my dad won't do any water changes for me, so I'll have to do one when I get into town mid-summer, and then resume them once I return again. I can get my dad to do top-offs, since it doesn't take much effort... I'll just leave some gallons of water treated with Prime for that purpose.
The only things my tank really needs dosing of is Potassium and Iron. Nitrates, I've only had to dose once a week, after water changes. I'm trying to keep them at around 10ppm. They're around 5ppm from the tap, and tend to stay there. I like to have them around 10ppm in case my fast growers decide to really take off, and suck up the nutrients. I'm hoping that the fish feedings are enough to keep these up.
Phosphates and micros I only dose once a week. So I can mix up 6 bottles for my dad to add to the tank once a week.
I'm toying with the idea of having an auto-dosing "system" which is gravity fed. I'm thinking of mixing up 6 weeks worth of very diluted Potassium and Iron. What I'm thinking is drilling a hole at the bottom of a 4 liter or so container for each, and attempting to see if I can control the flow to around 1 drop/minute, 24 hour feed.
I've read that these solutions can get all "funky" if mixed for longer than 2 weeks, is this true? I had a bottle of iron I mixed up, that I had standing by for about 2 months, and nothing funny happened with it.
Anyone has any suggestions to how I can keep auto-dosing ferts while I'm out? I'd mix a bottle of for each day for my dad to add, but that'd be 42 bottles, and since his stroke a few years ago, he's been pretty forgetful...
BTW, my photoperiod is currently 8 hours. Would it also be wise to lower it to 6 or less hours while I'm out?
EDIT:
Also thought I'd add a list of my plants, and see if anyone thinks I'd return to a ridiculously overgrown tank that chokes out other plants or possibly my fish.
