Gorillia Glue would work well.

Flowerhorns? Ack, ack ack!

Hats off to you, mate - that's some fantastic work. :bounce:

Very cool, Sanjay. Could you use the pH reading to drive a relay to switch a CO2 feed on/off? Are you going open source with your code, or are you thinking of producing these for profit?

Very cool Looks like the safe thing to do is avoid eye contact and be submissive.

Flourish is just for micros - do you need macros as well?

Yep, I just had a look at a can of Raid which has three active ingredients, and they are all pyrethoids: Tetramethrin (1,3-dioxo-4,5,6,7-tetrahydroisoindol-2-yl)methyl-2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropane-1-carboxylate Phenothrin (3-Phenoxyphenyl)methyl 2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropane-1-carboxylate Allethrin (1R-(1α(S*),3β))-(2-methyl-4-oxo-3-prop-2-enylcyclopent-2-en-1-yl)-2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropane-1-carboxylate In testing, the LC50 (concentration that killed half the test subjects) for Allethrin ranged from 2.6 ppb for bioallethrin in coho salmon to 80 ppb for s-bioallethrin in fathead minnows. That's parts per billion.

Good old permethrin - sounds much more cuddly than it's full name, 3-Phenoxybenzyl (1RS)-cis,trans-3-(2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate. "Permethrin is extremely toxic to fish and aquatic life in general, so extreme care must be taken when using products containing permethrin near water sources." "Permethrin does not present any notable genotoxicity or immunotoxicity in humans and farm animals, but is classified by the United States Environmental Protection Agency (EPA) as a likely human carcinogen, based on reproducible studies in which mice fed permethrin developed liver and lung tumors. Carcinogenic action in nasal mucosal cells due to inhalation exposure is suspected, due to observed genotoxicity in human tissue samples, and in rat livers the evidence of increased pre-neoplastic lesions raises concern over oral exposure."

Depends on your water. If you have high nitrates and/or phosphates out of the tap then frequent water changes can lead to algae. Each case is unique and needs trial and error to find a balance

Oops, edit -cos I have no idea what I'm talking about

Nitrogen would be more humane as it doesn't trigger the breathing reflex. There's a few industrial deaths every year where people get killed by N accidentally.

A bit off topic, but every cat owner should watch this video on the dangers of catnip :bggrn:

Countdown sells it, too. Prolly cheaper than a chemists.

Haha, C+H and The Perry Bible Fellowship are hilarious, in a twisted sort of way :thup:

It works as an anaesthetic. I wouldn't be confident I could locate a fishes brain, let alone stab it accurately. It's funny how you get emotionally invested in pet fish. I still enjoy fishing, but I get twinges of guilt sometimes. It must be terrifying getting hauled out of your environment in such a painful manner :tears:

Couldn't agree more, Alan. It's just hard to resist correcting gramma nazis when they make mistakes. It kinda makes the same point you just did

Yanks don't spell it that way either, it's just a common misspelling

" They should not be kept with Red-tailed Sharks (Epalzeorhynchus bicolor) unless the aquarium is large and well planted, because that species is very aggressive towards all its relatives. " http://www.thekrib.com/Fish/Algae-Eaters/ Reading some of the comments above was a bit of a surprise, as the four I have in my 450 community are very placid fish. They are active, but don't go looking for trouble.

Let's all start arguing about brands like good little consumer sheep. You're so brainwashed you don't even realise it :facepalm:

Well, duh - I don't know many living things that are. From what I've read, you can train most problem ones out of bad habits or nervousness, and get them to bond with you - especially if you get a young one. Sadly I don't have enough time to raise one with the care and attention it would deserve Anyway, negative comments aside, you have to admit that one's damn cool
