I would up the CO2 to about 25-28%, then yes you need to dose macros and micros. EI is a good method if you don't like to test, but if you want to fine tune it, you can modify your dosing and do less water changes like 30% weekly or 60% every two weeks, depending on your concentrations. You do need to test though to get to that happy medium. I see you have some swords, so I suggest some flourish root tabs under those, or some ADA Iron bottom. Just make sure they are buried straight down in your substrate as to not get it in your water column. Don't wait to see IF you need to fertilize, because you will get one hell of an algae bloom. You will inevitably need to get to it, so start out on the right foot!
Where can I get the recommened doses of macros and micros? Also, the substate is ECO-Complete do I still need to get some flourish root tabs for the swords? Also, what's the deal with the roots not being allowed in the water column? I'm a newbie!
Just placed an order from gregwatson.com for the following and will be doing a weekly water change of 50%.
