Hi pedro, wonderful tank as always
Is there any reason for such a low dose of Mg compared to EI?
I don't have problems with low GH.
I know that this is doesn't tell me 100% sure that i don't need Mg (because GH is also Ca) but knowing the quality of water in my area i started to give lower values and don't really see any lack of it.
Pedro, do you use other "micro" or trace elements despite MgSO4? In my tanks I found that red plants positively react on increased level of PO4 comparing to NO3 (you already had that) and additional Fe.
Also, I noticed quite big heater in your tank. That's not big problem in big tank, but in my 60L I want to get it off the tank to have more space for scape itself, but unfortunately can't have external heater (Hydor, but also it has bad reputation, so additional temp controller is a must, IMO). Have you ever considered switch to external heater?
Yes. For the last 4 or 5 setups i've been using Chelated Trace Elements from Aquariumplantfooduk but have ordered this week the Drak Micros. I've been reading some good stuff about it.
I also used (every now and then) ADA ECA but when i started with the experiment i described it was over and i still don't have it.
In Lost Nature you can't find an heater I use an Hydor and i know about the problems they're having but had no issue for the last 8 month (I bought it in December).
For this one i wanted a filter with heating so i never had the will to buy an external one. The heater is already out (summer...)
