Ditto! Captain_bu put it very nicely. And if you do have a lot of light over that tank, you're just putting up a sign for the algae that says "Party Here!". Cut the light. Your tank is no where ready for a lot of light. Not yet.
I noticed something else. Do not bleach your plants. There are much better ways of killing algae from them that do not require that the plants be uprooted or harmed.
BTW, if you can't find hornwort in your area, you can get it on eBay
. Just make sure it's not the plastic kind!
I actually have bought hornwort from this seller
one time when my tank needed a ton of plant mass. Keep in mind that hornwort is a weed so just a little should grow quickly.
Also, stay away from Anacharis. It's another plant used much like hornwort, but Excel melts it.
If you want to stick with low maintenance plants, look into crypts. They will sometimes melt when first planted, but they come back beautifully. They're very hardy and will do well in a low tech situation.
Regarding ferts, I just explained it in detail in another thread. I suggest that you read the entire thread (it's not very long). But the posts where I explain the ferts is this post
and the one after it. I think you will discover, however, that your schedule of not being home will make it difficult to use EI dosing.
With all you've said, I'd lower the lighting to a low light tank, skip EI ferts but put Root Tab ferts in the substrate, stick with hardy, low maintenance plants (and not just java fern and anubias), and if you can afford it, get pressurized CO2 since you won't be around to dose Excel every day. You are the very first person I have ever suggested not fertilizing, but with your schedule, I think you're better off with a no fert tank and get plants with that in mind. Plus, the root tabs will help. But definitely reduce the light. You cannot have high lighting on that tank unless you really do want to throw an algae party.
