Ei ferts and CO2 + some other stuff

Hi all=) So i will be setting up my first high tech tank(60gallon 38x19x19inch) here in two weeks and have all my ferts and equipment in and just wont to get a good grip on what my scheduled should start off as. Since its my first high tech setup i really want to do it right the first time with minimal problems. So in the chart i got with my Ei ferts it has 40-60gallons and then the next one is 60-80gallons. So my question is do i use the 60-80gallons numbers or the 40-60gallons numbers? Or do you have a better method for dosing amounts? second question, with the co2 what is the recommended bubbles per second for starting? I was thinking somewhere around 3? And finally my third question is for lighting what is the recomended time i start with? I am using 3 kessil a160we tuna sun lights so i was thinking i should start with 7hours and work my way up slowly to 9 or 10hours. Here is a link to my tank journal if you want to get more info on my setup.https://www.plantedtank.net/forums/sh...089&highlight= .I have been really working hard to research everything from top to bottom but i really would like to here everyones thoughts on this part. I am hoping to have minimum algae growth and what not but what is your experience with starting a high tech tank and algae issues?FYI I will be planting very very heavily as i have research this will really really help.
Thanks in advance to all the answers, i really do appreciate your help!!!!!!

For fert dosing: I would grab some milligram scales and go here.... http://calc.petalphile.com/

Ferts: I agree with Lee; if you use the calculator you can specify your exact tank size, and will be directed exactly how much to dose (in grams). In the meantime (until you get a dosing scale), the calculator also allows you to see the result of dosing each fertilizer for a given amount of teaspoons. If you try this, you will see that dosing for the 40-60g tank is closer to mid point that EI recommends than the 60-80g (which would be on the high side). I would stick with the 40-60g chart for now.

CO2: For good growth, and to limit algae, many will recommend you reach a steady rate of 30+ppm of CO2 for the photo period. Counting bubbles is not enough. You need to attempt to measure your pH prior to starting CO2, and then increase the bubble rate until your CO2 drops by 1.0 - 1.2. Some people use a drop checker, and when it turns the correct color then you have reached a good level of CO2; but the pH method is a good way to start. It will take you some time to slowly adjust the bubble rate up until you reach the pH drop you want. And you have to be careful with your fish/shrimp; as you increase the bubble rate watch for signs of distress (as too much CO2 is toxic to them).

Lights: I agree with you approach to limit the light at the start, and increase it only after you are confident your tank is algae free. Too much intensity, or too much duration is a recipe for algae.

It is good you are planting heavy, and make sure your tank has good circulation. Root tabs may help as well.

Yea I have a drop check, but when starting I didn't want to over do it and possibly kill a fish so I was wondering what would be a good number to start at. For Ferts I will get a scale asap! I would rather start of with the absolute correct amount . Thanks for the info guys it really helps!!!!

So I saw you said to much intensity is also a recipe for amalgam when first starting. In this case should I keep my light intensity at half with the 7hours of light on? If I had to make a rough estimate at what my par is going to be I would say some where around 60+ just guesstimating

For CO2 bubble rate I would estimate you will need probably 5-10+ bubbles/sec for your 60g, so starting at 3/sec should be safe. Do you have a way to create surface agitation if you make a mistake with too much CO2? But if you go slowly you will be fine.

My advice is to be cautious/patient with light the first few days/weeks until you see that the plants have adapted and are growing. I don't feel comfortable advising to cut intensity from day #1, but from experience can say that I had to cut the intensity (Fluval LED - don't know the PAR) to solve some algae issues. I can only suggest to watch closely and be prepared to cut intensity based on your observations. You don't want to deny your plants good PAR, but you need to watch if algae is gaining the early upper hand.

Alright thanks I'll start with 4bps if that's the case! I won't be stocking fish for about two weeks after setup. My media is already cycled for the most part but just want to play it safe with the high ammonia count in the ada awua soil!
