Re: Getting rid of snails in Pygmy corydoras tank

Hi all, Thanks Darrel. I didn't realize copper was that much more effective in soft water. Tom Yes, it is one of the issues with <" acid rain ">,the lower pH solubilises metals from spoil tips etc. <" Most copper compounds "> are insoluble in water, but many of these are soluble in weak acids etc. c...

Re: Getting rid of snails in Pygmy corydoras tank

Hi all, I have very soft RO water in that tank, keeping it soft for the neons primarily (they have spawned there)........My primary concern is copper.......Killing the snails is easy, changing the water is easy, I just don't want to kill those corys. Copper (Cu) is much toxic in soft water, because ...

Re: Getting rid of snails in Pygmy corydoras tank

Hi all, I have a tank with Pygmy corys and neons. And snail, don't forget the snails. .........Any suggestions? I'll be honest I'm a snail fan, so keep the snails? I know they aren't to every-ones taste, but they perform a useful role in detritus removal. I definitely wouldn't go for a chemical solu...

Re: Need more help with my columbian sharks please

Hi all, .........I had been told by 2 3 manufacturers the GH of the marine salt is already quiet high even at low salinity but I had to check myself and it turned out they are correct (of course what Im saying is based purely on Columbian sharks) the GH would probably be too low with RO water for a ...

Re: How low is too low for KH

Hi all, The 8 hours for the oase 650 is because it is the second filter and used to supplement the juwel filter bioflow L stack as the standard juwel set up has less than 3x turnover for a 350ltr tank at 1000lph as well as only being specified for tanks upto 60cm. OK, as the others have said, you ne...

Hi all, Tank looks good. Filtration standard Juwel rio stack, foam and ceramic media full time with oase 650 biomaster canister filter again with foam and plastic balls operating 8 hrs per day. So possibly overkill on the filtration but you can never have too much can you???? I think we mainly tend ...

I have read stories about tank crashes and am concerned that the low KH cou...

Re: Gut microbes of wood-eating Panaqolus and Panaque

Hi all, Putting it in my own words, these fishes live from the rotting bacteria, not from the wood itself. Or would this be to bold to state? No, I think that is right. We have a bit of thread on this, starting in 2010 with < Little Panaque soon...... >, via < Teeth degradation in Panaque >, from 20...

Re: Need more help with my columbian sharks please

Hi all, What I think Darrel meant was Apparently the EU (European Union) has rules for the quality of potable water (new to me), and you may have heard Great Britain has left the EU - implying the EU rules will not have any meaning for the UK. Darrel expects the rules for potable water to become les...

Re: Water parameter

Hi all, To the scientists out there, what about using a deionizing unit here? If there is not an issue with the water being too hard, that would remove the nitrate. However, I do not know if it would also be removing other ions that are desirable to have. You can get specific anion exchange resins t...

My suggestion would be to stop overthinking it..... I do use a 50/50 of tap to RO water for mine.
I'd agree, probably start there and see what happens.

Re: RO/DI questions - Hoping to breed L-134's & L-182's

Hi all, Very interesting, thank you for the reply. If thats the case, what is the target TDS range you would recommend for these species? I haven't kept L134 or L182, but I grew out Hypancistrus debilittera and Hypancistrus sp(l333) using this approach, and have had Otocinclus sp. spawn successfully...

Re: RO/DI questions - Hoping to breed L-134's & L-182's

Hi all, ......The PH levels on both of these mixes was higher than I was expecting, seeing that the pure RO/DI water had a PH: 6.4 - 6.6. My main goal is to lower my PH to around 6.5 - 7.0, while maintaining a relatively stable KH so that I don't experience any large PH swings. ......... You don't n...

Re: Looking for a new biotope to model? How about a floating litter bank habitat?

Hi all, .....Another thing, you'd lack the food source that makes these sites popular with the fish - the high abundance and variety of invertebrates feeding on the plant matter, which are then food for the fish. I suppose you could stock your tank with inverts... but which ones? Scuds? Ghost shrimp...

Re: Looking for a new biotope to model? How about a floating litter bank habitat?

Hi all, While such a tank would be very intersting, the problem would be the decaying organic matter. That is, the constant worsening of water quality. In nature the system is large, our tanks are relatively small, even a large one. I agree with @Bas Pels, you would need to find a leaf that was very...
