Soaking Bogwood

are the four pieces of bogwood I purchased, currently soaking in a vat of water
before adding them to aquariums in the fish house, the brown stain in the water
is caused by the tanin in the bogwood leaching into the water. Boiling and
soaking for long periods can reduce the tanin leaching into the water, the use
of carbon in a filter will remove the tanin from the water but can also remove
other nutrients required for plant growth, regular partial water changes will
also dilute the effect. I quite like the colour, and it appears more natural
for the fish that I keep. It also helps to acidify the water  in the
aquarium. You usually have to pay for chemicals to do this e.g.
Tetra Blackwater
. (the observant amongst you will notice this vat was last filled
with a potassium permanganate solution, this has been siphoned off into 20l
bottles, so I can dispose of, at a rate of 500ml (half a litre) a day!)

I’ve planted out my display tank this evening using Aquatic Potting Kits,
I’ve inspected the Totra Vallis, I received from Java-Plants and they are of
very poor quality unlike the Amazon Swords I received, I’ve emailed Java-Plants
for comments. All 25 plants look like they need a priest, very brown, I don’t
think they’ll recover.

On the subject of emailing suppliers, I’ve also emailed Pond-Supplies UK,
because I’ve noticed stress fractures/cracks on my new Air compressor, and
that’s not been in service very long. Air is leaking in via these cracks, and
not via the air-inlet.

On a happier note, my "aquarium sealant fix" seems to have fixed my other
Hi-Blow type air pump.
