    Went RO, lost tens of Cories

    Hi all! Sorry, long story...I turn to you with this (at least to me) mysterious case what began last September-October as we started collect rain water for our five aquariums. This was because we have a bit nasty tap water with pretty hight TDS (450-530uS/m) with lots of NaOH and NaCl, other...

    N2, harmfull or not?

    Hi again! This has been discussed every now and then and -where, according to some discussions or conclusions it is harmfull to have N2 gas in aquarium but on the second place its just good for plants and just one nice and easy way to get rid of N (NO3). I guess this varies and maybe depends...

    Emersed hybrid

    Hi all! This is my latest attempt with paludariums and emersed culture. Veggies moved three weks ago from 250l to this 600l wich was converted to be a paludarium. There is a mix of few emersed aquarium plants growing on and between bogwoods but also room plants. This is still under...

    RO installation when washingmachine is not an option

    Hi all! I desperately need some advice what to do next. I finally got my JBL RO-unit. There is washingmaschine installation preset (immovable if not cut away) to take clean water. Since wm is definetly necessary for our member-of-six-family, what are options to connect RO to something else...

    Who is eating her plants? Or is it?

    A member of local aquarium forum asked help. My best bet was that the main issue is something else than a pest, but what do you think? Something is definetly going on, but what? She described that a pest or some kind of insect is monstrously eating her plants. Fast. The insect is very small...

    (How to...) Get rid of filtration

    Howdy! This must be a stupid question, but never done this before... So, I have a big Hamburger matenfilter in my 600-litre tank. Young fish, not-so-crowded so I think it might be good idea to get rid of filtration now (or never). It has been kind of wannabe-amazonbiotope for six months with...

    Stopped carbo, (only) Java ferns struggling

    Hi! Maybe this issue would belong to under CO2-thread, but here we go anyway... I consider it as a fert. Well, the problem is melting Java ferns, many sorts of species. I slowly stopped EasyCarbo in May->June, redused/adjusted lightning at the same time but still kept/keep fertilizing, as...

    If airstones were so effective...

    Hi! Thinking of this ever lasting discussion of how effective aistone is when it comes to oxynating the water, why doesnt it add nitrogen to water along the oxygen? Air contains nitrogen 78% and oxygen 21% so if O2 were dissolved why not nitrogen? Is N so hardly dissolved...??? I personally...

    Mission impossible?

    Living with really high EC/TDS

    It seems that we are exeptional blessed with high electrical conductivity here in my hometown. Usually EC here in Finland is pretty low, 100-200uS but we... We do have (tap)around 600uS, wich is more than in lake Tanganyika as far as I know. Sometimes I feel a bit lonely when landmates talk...

    Mg+K+Fe=no NO3???

    Sounds impossible, or does it? A hobbyist fellow of mine has noticed that that adding Fe, K and Mg to a water with NO3 (tap 12,5mg/l), NO3 disappears totally. He has repeated this few times in a bucket with the same result. How come? He has been using JBL drop tests so I think they should be...
