2 filters, 1 eheim 2026 and 1 fluval 305.
4xPC 65W, schedule(2-4-2) first hour is 2 then all 4 for five more hours then 2 for the last two hours for a total of 9 hrs.
I use EI for 60-80gal, i also added extra K.
I dont understand the problems with the pictures, i rick click and opened in a new tab and they are working fine.
I doubt that extra potassium is of any value. Do you have a full dosage of phosphates? Any shortage in phosphates will stop the plant growth. Also, how do you know you have good CO2 level?
I think you have far too much light for the midday burst. 4.3 watts per gallon is really a lot of light, unless you can be sure everything else is being provided in concentrations good enough to meet the high demand that the light is driving. If this were my tank, I would only use two of those bulbs, and no midday burst.
Do you have very good water circulation, so all plants are swaying in the current? The lack of adequate circulation, with that much light, means the CO2 can be used up locally, with no new supply being brought in by flowing water.
what do you mean by full dosage of phosphates? I use the the EI recommended 1/4tsp each time i dose, to say 1/2tsp and see how everything looks? For current i have two spray bars hooked up along the back wall blowing towards the front glass, they push a light current, i also have a koralia 1 in the middle also blowing towards the front. Should i swap the spray bars for nozzles? or should i rearrange my tank to allow better circulation? Or do you think the 2 spray bars + the koralia all blowing forward is adequate?
edit: dont know if this makes any difference but i tested my phosphates and they are between 5-10ppm.
The only reason I asked about phosphates is that some people are still convinced that phosphate is a sure cause of algae, so they omit it. You should have plenty when you follow the EI dose schedule. You didn't mention how you measure your CO2 to be sure you have enough. It seems like inadequate CO2 is the cause of most of our plant problems, so that is a good thing to check out thoroughly.
It is hard for me to evaluate someone's water circulation. If I were to guess at what could be your circulation problem, if you even have one, it would be the spray bars. I found that switching from a spray bar to Aquarium Plumbing: Directional U-Tube helped my circulation a great deal.
Is that a sword plant I see in the background?* If it is I think it may be part of your problem, as I think you are lean on your dosing.* I have noticed problems like this in my tank where some plants do really well and some look sad like the pics.* I doubled ei dosage and decreased lighting and have noticed a lot of improvement as well as removing 1 of my swords, I am only running 1.25 wpg of hot5 on a 125 gal plant growth has slowed down but every thing is lusher and heathy looking.* So I agree with VaughnH as to decrease lighting. What is the pic of the plant as I want to say it is either a ludwigia or rotulla speices?
just ruducing the lights doesent seem to always fix the problem. I tried lowering it to two lights for a few weeks and did not see any notable increase in growth. I also have to then worry about my red pigmented plants turning green, and my HC all parished due to not enough light im guessing near the substrate.
The red plants I have been told just because they are green doesn't mean they aren't heathy. I still think you might be a little lean on ferts and with that much light isn't helping you any, the plants might not be getting enough ferts when you decreased the light before also. I am adding 1 tbs nitrate, 1/2 tsp phosphate, 1tsp potassium, and 1/2 tsp plantex daily on my 125. I disagree about the roalla's being easy to grow as I have had a few of them and have been one of the difficult ones for me as well. I cicled the leaves I was looking at as a sword as I can't see them being a val but look and make sure.
ill take a better picture tonight, im not 100% savy with all the plant names. I also stepped up the ferts to the 100-120 EI dosing scheme and reduced the lights to 2 bulbs for 4 hours, 4 bulbs for 1 hour, then 5 more hours of 2 bulbs.
Here are some updated pictures after about a week or so of double EI and cranked up co2. I have also included some pictures of what my setup looks like, I would appreciate any feedback on any changes ect...
Picture #2 is something that i cant figure out, leaves that are floating around the tank look like this. What can be the cause of the pin holes?
well im sure that its not K since i doese 1.5tps Kno3, 1/2tsp kh2ps04, and 1tsp k2s04, its a 60gal with 2ish wpg, high co2, anyone else agree that it looks low on K and N? if so ill continue to increase my EI dosing.
sorry they yellow may be due to the fact that i turned on all 4 pC lights and did not use any lighting correction on my camera.
