As long as nutrients aren't limiting there isnt really an optimum level. On a truly unlimited tank the maximum uptake of NO3 by plants is recorded at 20ppm a week. So as long as you are at say 25ppm, I wouldnt worry. Consistency is more important than aiming for an exact figure. If you got...

Yeah it is, Equipment make/model/size: 2kg FE Quantity for sale: 1 Reason for Sale: not needed Delivery or Collection: both Sales price: £15 Postage & Packaging: £10 Location: worksop

I've always bought mine over the Internet and Shops always sell them over the Internet too

I have a full 2kg FE for sale, £15, postage is £10 Thanks

How long has the tank been set up? Just trim the brown leaves off the water sprite, it will grow back, it can be common for plants to die off at first as they adapt. Aaron

I'm guessing those kits want you to measure the tank water though? You need a pH and KH reference so you can work out the exact PPM value. If those kits want you to test the tank water then that is no good as it already contains other acids affecting the result. One could quite easily have tank...

How much surface agitation do you have? It could be the lack of oxygen, ample surface agitation is required when running high CO2. A nice steady ripple across the waters surface is what I aim for What signs are the fish showing also? If the plants are showing a deficiency in carbon and you...

No need to do this either, Aaron

Lime green is fine, that will be about 30-35ppm. I have pushed it into yellow before and so have others (which is about 40ppm) without any ill effects. But this depends on the setup tbh :good: A drop checker is a CO2 test kit? You test the pH and cross reference it to a known dKH (assuming...

Yes its a 2ft tank, I've pm'd you

Hi, sorry when I put 3x I meant there were 3 strips of 24 LEDs (72 LEDs in total) that run off 1 plug. It is a 230v 3 pin plug with a 12v output. The strips are 25cm long Thanks, Aaron.

That is true; nutrients will feed algae but they do not cause algae That is where most people get mixed up. Aaron

Sounds reasonable, stick to the manafacturers guidelines on carbon dosing, as it is toxic to organisms. People do dose 2x the recomended dose without any problems though; I have dosed 5ml on a 60l with shrimp (which are said to be the most affected) and everything was fine. It was a very fast...

You are using easycarbo, techincally making your tank high tech so the values would be higher like someone who is using gaseous CO2 injection. You could start of dosing every other day and see how you get on, if any defficiencies show then start dosing daily. However, if your plants are...

These are the maximum uptake rates (based on a tank with no limiting factors): Nitrate (NO3) 20ppm per week/ 2.85ppm day Phosphate (PO4) 3ppm per week/ 0.43ppm day Potassium (K) 30ppm per week/ 4.29ppm day Magnesium (Mg) 10ppm per week/ 1.43ppm day 1ml per 20litres adds this: (Taken from...

ahh right I was thinking you just had roots (no leaves) :lol: Yeah it will be fine

Post a picture, that seems strange unless of course you have been ripped off. Where did you buy it from?

If they need nutrients, they need nutrients. There is no way around it. Middle-back is the best place for them, usually so the leaves a springing out from the lower foliage but it doesnt hurt to be different!

bump

no wall, looks too crowded IMO due to having the moss on the wood and with it being a small tank. A graduated blue background could look good. Aaron

You are correct in saying it destroys bacteria (harmful or not), but you also make it sound as though it kills the nutrients we dose which cannot be killed as they are not living... It can however break down the chelators but tbh it wont have a detrimental effect. I have used one in the past but...

filters filter out the wste in the tank, wether it be the sponges catching debris or the bacteria in the filter nitrifying ammonia. Powerheads are just a pump that creates extra flow within a tank. Let us know how you get on, as I'm sure you know though light + NH3 = algae. So if NH3...

What are the lighting levels? Providing you have low light then it is viable.

Well anything below 20ppm is limiting. Anything above 30ppm won't give you much better growth rates. Thanks, Aaron

Yes, I have just read the guide on here, it says 5pm x3 per week - perhaps this is where the confusion lies?

EI was calculated on a maximum uptake rate of 20ppm NO3 per week, so that wouldnt work out :good: Thanks, Aaron

Have a read of this; http://www.fishforums.net/index.php?/topic/204993-no3-dosing-toxicity-for-fishshrimp/ 5ppm over what time period? Aaron

Have a look at the guide in my sig, explains everything :good: Aaron

There isn't a definite answer for this, but most would say it isn't exhaustion, but rather they are full! As soon as they have taken up enough CO2 the rate of photosynthesis drops, this is particularly noticeable in fine leaved stem plants such as myriophyllum and limnophila where they close...

The reaction for photosynthesis if it helps; 6CO2 + 6H2O => C6H12O6 + 6O2 (Carbon Dioxide + Water => Glucose + Oxygen) Now you can see why oxygen bubbles are produced. Plants are constantly producing oxygen as I'm sure you know, its just as said above, O2 is being produced faster than it can...

lol, not much point in odd bits then

I had some EI solution that I still had mixed up. Once every 2 weeks I would add that. I didn't bother with easycarbo, as this is then techincally making it a high tech tank. Aaron

Yeah, if put a drop of vinegar on the rock and it fizzes then it will raise your pH :good: Thanks, Aaron

Exactly the reason why people shouldnt complain :P

I can get a pic tomorrow if you like, but heres what I used in mine (120 x 45 x 40cm) What size tank do you have? Thanks, Aaron
