Hey Guys this is my first post here. I run into Tom Barr a week or so ago in another forum and we had a great discussion about the subject we are all here for. My tag there was The Plant Man. I had never heard about him or his EI method. I’ve been practicing growing plants for about 5-6 years now and “thought” I had a firm grip on it. I mean I do all right. But Tom opened my eyes about a great many things and I just wanted to say thank you Tom Barr.
You’re all right.
The tank is a 46 Bowfront with 2 T-5 fixtures 4 21watt bulbs 2 x 7,600k and 2 x 10,000k. Filters a 2215 with 2217 impeller and a 2217. 4 year old flourite substraite I do 35-40% water change with 15ml Tropica aqaucare ferts per week (for now).
I am not yet completely using his method but not because I don’t want to, I’m just not set up for it yet.
I did make a few changes to my DIY set-up in accordance with his ideas and they have made a remarkable difference!
Some pics.
This is when I set it up just over 3 months ago.
This is now, today
Changes I made because of what I learned from Tom are.
I dropped my light down to 1.8 watts from 2.2 watts.
I added a third bottle to my DIY Co2 set-up
I bought and installed a Drop Checker with 4dkh solution in it and use API's PH drops.
I modified my method of defusing Co2 to get better efficiency.
I dose more ferts and do larger water changes once per week then I was
I will be purchasing a Rexx Co2 system in the future.
The difference in just about 2 weeks has been amazing.
Before adding extra Co2 DIY bottle and after, I defuse it with a power head and an added tube that is restricted at the end. From the three bottles I get a steady uninterupted and smooth stream of tiny bubbles out the end of the tube.
I was dealling with a bit of an algae out break 2 weeks ago but it is mostly cleared up. I am just stuck with a bit of Green Spot on the anubias.
