In our comunity tank, well my wifes, it has quite abit of bog wood so we get alot of tannins in it.

I know this is helpful as most my pleco tanks are a slight shade brown.

But wanted to clear this in comunity tank. And reading a thread started by JackGillett and someone mention Seachem Purigen. I did a bit of reading and bought a bottle off ebay 250ml. Liked the idea of it as you can re-activate it and reuse, ya i know i am tight.

Well water change tonight and cleaned filters, so i thought i will give it a go. So put half bottle in net bag about 125ml and put in botom of filter next to carbon.

Well 2hours later i just thought i would check tank and turned on lights.....

OMG cant belive it :D:D:D

The water in tank is like tap water, crystal clear. Did a uick water check all paramiters still the same.

Highly recomend it.

Purigen® is a premium synthetic adsorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen® controls ammonia, nitrites and nitrates by removing nitrogenous organic waste that would otherwise release these harmful compounds. Purigen’s™ impact on trace elements is minimal. It significantly raises redox. It polishes water to unparalleled clarity. Purigen® darkens progressively as it exhausts, and is easily renewed by treating with bleach. Purigen® is designed for both marine and freshwater use.

Use in a fine mesh filter bag. Each 1 L treats up to 4,000 L (1,000 gallons*) for up to six months. Exhaustion is indicated by a pronounced discoloration of the beads to dark brown or black.

One point that we must very aware of when looking for a clear tank is that most Plecos have what is called an omega iris.
This works differently to our iris and in fact to all other iris.
The iris is a form of shutter to control the amount of light that falls on the optical nerve. (This is a simple explication)
The Omega iris has no rotary closing so it uses a form of “Blob” to control light by expanding and closing.
The light that Plecos normally encounter is dim and has a lot of suspended matter floating in the water.
When we remove the elements that make up this water and have what we call clean water we are subjecting the fish to a problem .It will have to keep adjusting the eye to the bright light and will in effect look like it is Blinking.
Myself I am not happy with a tank that is “clear” but some people do want this so choosing the fish to suite the tank is a must.
Bright tanks are for fish that like clear and clean water mainly fast flowing water over stones and rocks as no disturbed matter can cloud the water.
Again a case of choosing the environment and the fish rather than the end result.

do most members keep their water tea color

I always boil my wood before adding to my main tank , as I didn't want the ''tea brown ''water, but did not realize this about their eyes. I keep my tank bright for about 2 hrs in am ,then dim . Also bought blue lights , shut off top dimmed light 2 hrs before bed and plug in blue for 2hrs.

So am I getting this right ? some or many members here don't keep their plec tank water clear ? :dk: Obviously we want what is best for the animal, so what do most do ?
thanks , Georgie

Hi all,
A bit of quick answer as I'm away from home. As Mac says most plecs are nocturnal and have an eye iris adapted to low light conditions. If you don't keep any plants there is no reason for having any lighting, other than some low intensity lighting to allow you to see the fish. Although plants don't occur in many of the biotopes inhabited by plecs they are useful in the aquarium because of their extremely beneficial effect on water quality. The tannin, humic acids and DOC produced by bog-wood, alder cones, catappa leaves etc. have many bebeficial effects as well (including complexing heavy metals), and if you remove the tint you are removing these compounds. Personally I'd go for tannin stained and planted every time, it gives you a bit more of a reserve and a little more of a chance if anything goes wrong.

If you keep a planted aquarium you need enough light for healthy plant growth, but you also need to create dark areas where the fish can spend the illuminated hours. Your fish will also probably become entirely nocturnal under this lighting regime.

I'd recommend Pete's "plants on aquarium sponges sticky" for examples of a plec friendly planted tank.

cheers Darrel

i also keep my plecs in the coloured water, it is their natural environment I find. Never had a problem. I do however use a blue light for 10hours, as the tanks are in the shed and have some plants. You will find that the tanins over time reduce anyway after leaching. As i use large pieces of wood, I cannot boil them, but I use a large barrel and soak the bog wood in that for 4weeks. No only does this clear some tanins, but being outside it grows some of that aufwuchs, which Ls nibble on. Cheers jk :thumbup:

thanks everyone , now I got some re-thinking to do and will look up your suggestion. I do keep some plants , but that is for shade and to help keep nitrates down. I don't spend alot on the plants anyway, but I see your point that bright light and clear water will force them to become totally nocturnal. I appreciate the info and darn, I just spent 3 days boiling out a great pc of rooty-wood , I had to keep turning it in the pot to get all areas...finally got the water clear ...and my hubby thought I was cooking for us ....no, it's wood for the main tank....again... got a grin outta him ,so I guess he is getting used to it. Well for now ,I will create some shady places , and I do have alot of wood and hidey places , just want them to be as comfy and happy as possible ,so thanks for your take on this . Georgie
