Hi. I've finally got my 180l tank up to something like I want it: Sorry about the reflection! I'm dosing with EasyCarbo (6ml daily), and EI dry ferts (1/2tsp KNO3, 1/8tsp KPO4, 1/8tsp trace, 1tsp MgSO4 all three times a week). Does this sound about right? Filter is a Tetratec ex1200, lighting 90W juwel T5s. All in all I'm pleased with how it is going. I find that the plants on the left, under the spray bar, grow faster than those on the right even when they are the same type, so I'm planning to extend the spray bar right across the tank. Hopefully this will spread the nutrients more evenly? I'm trying some Cyperus Helferi on the right, but it isn't really growing much and has some brown spots on the leaves. Any advice from you experienced guys is welcome. Likewise with the clumps of HC which just sit there doing nothing. Would it help to replant them as individual plantlets? All the enchinodorus are thriving. I'm very pleased with the Enchinodorus "Red Diamond" in the centre - it has produced some lovely red leaves. As they get older though they turn a kind of bronze colour. Even new leaves now seem less red. Would this be normal or is is a nutirent/light issue? My other red leaved plants (Alternanthera and Ludwigia) still have some red but it is less vibrant and growth is very slow. I guess this is a light issue. The one on the right (I can't remember which is which!) suffers for patchy and holely leaves on older growth. I'm thinking of taking the plunge into pressurized CO2. Can anyone recommend an off the shelf system? Although mindful of the expense I'm rubbish at DIY so the FE solution is not my cup of tea. Also would it really be that useful on the set up I have? Thanks in advance for your thoughts and opinions!
