    What size substrate for geo (mirabllis) ?

    Hi all, It is a mess, which is why I always use conductivity, but if you did want to convert to "ppm TDS"? The conversion factor is 0.64 (100 microS ~ 64 ppm TDS) for freshwater, this is based on the assumption that the predominant ions in freshwater are calcium (Ca++) and bicarbonate...

    Worried about my dude

    Hi all, I've got access to a PC, so I'll link in some threads on UKAPS. Seasoned Tank Time <"https://www.ukaps.org/forum/threads/nano-tank-ish.69484/page-2#post-693867">. A thread with contribution from Dr Ryan Newton at University of Wisconsin- Milwaukee...

    thinking of adding GHO ORGANIC HUMIC ACID SOLUBLE GRANULES 93% humic and fulvic.

    Hi all, No, but I only <"drink beer"> (or Espresso Martini). In terms of acids? I would prefer a "weak acid", like citric acid, but there is no reason you can't use HCl. @regani (a chemist) has some useful "cocktail"comments in...

    thinking of adding GHO ORGANIC HUMIC ACID SOLUBLE GRANULES 93% humic and fulvic.

    Hi all, Muriatic acid is HCl, and a "strong acid", so you need to be very careful with it. Cheers Darrel

    Worried about my dude

    Hi all, My thought as well. I don't like "cycled" as a concept, it isn't useful because it suggests a switch from unsafe to safe and that doesn't reflect the microbial reality. I'm away from home at the moment, but search for "Seasoned Tank Time" and that will give you some more discussion...

    Lower Orinoco plant ID

    Hi all, Welcome, nice video. Egeria is more likely, Rotala is an old world genus. Definitely a Nymphaea and it looks like a Macaya sp. and Tonina fluviatilis at ~1:30. Ludwigia inclinata would also be appropriate. cheers Darrel

    Books on Apistogramma

    Hi all, I've got both of those. I have hard tap water as well, and am a rainwater user, but I'm going to guess (all right I know) that it rains a lot more in SW England than it does in the SW USA. cheers Darrel

    Would love to see an "attitude" list of Apistos.

    Hi all, Apistogramma trifasciata. Cheers Darrel

    A. Cacatuoides fry(s,es?)gone

    Hi all, Not really, it is like the others say, a pretty bad sign. My suggestion as well. One of the reasons <"I like a lot of plants"> is that they have a beneficial effect on water quality, and I'm not a <"particularly good fish keeper">, so I need all the help I can get. cheers Darrel

    Apistogrammas eating/disappearing eggs

    Hi all, I think it is a chubby Pencilfish? Possibly Nannostomus beckfordi? I'm a "more is more" (and a floating plant obsessive) as well. Could you chuck a lot more structural leaf litter in? cheers Darrel

    Unknown plant

    Hi all, I think it might be Macaya fluviatilis as well. I'm going to guess that there are just a lot of diffuse leaved plants in the rheophilic aquatic flora and that is largely current related. In terms of Aquariums I'd suspect that people like the contrast between different leaf shapes and...

    Dicrossus 420 L

    Hi all, I'm a snail fan as well, and my snails <"never get very large">, just like @Mazan 's. That is one of the things with cyanobacteria, it can multiply very rapidly, and that is also why I'm not keen on black-outs, bactericides etc. they are just a sticking plaster and they aren't...

    What to do now?

    Hi all, I'm obviously not an unbiased observer, but I am proud of it, and it works. Cheers Darrel

    What to do now?

    Hi all, That was why I developed the <"Duckweed Index">. It is a mechanism for allowing you to keep your plants growing on <"petrol fumes"> and makes use of the fact that a plant with access to <"atmospheric CO2"> is never carbon (C) limited. It is Diana Walstad's <"aerial advantage">. The...

    A. Sp. vaupes and A. Sp. gillspot WC

    Hi all, That is what I'd suggest. Go to Utaka and have a look. cheers Darrel
