    H202 Water Treatment

    The Royal Society of Chemistry once offered a £1M reward to any one who came forward with a substance with 'no chemicals in it'. They were required to lay off the liability with insurance. I despair at the lack of scientific and technical education. What happened to the 1944 education act. I am...

    H202 Water Treatment

    I do not think that I can enlighten anyone. From personal experience water clarity is greatly improved with UVC see @Dr Mike Oxgreen above. I use rain water in my water change regime which is often discoloured due to tannin leachate and microscopic leaf and seed particles from the roof...

    H202 Water Treatment

    It is difficult to comment without knowing the reason for the addition of H2O2. If it is for oxidation of metabolic wastes then an alternative approach could be with UV. See Wilki:- 'Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to...

    Dr Timothy Hovanec's comments about Bacterial supplements

    The scientific background to the "Leaf Colour Chart"

    Thank you for your response. Looking forward to your article. I have difficulty with floating plants, the surface current moves them to the front pane and they tend to become submersed and rot.

    The scientific background to the "Leaf Colour Chart"

    Interesting chart & link. Any chance that the numerical scale on the back (not visible or stated in the link) could be printed on the front. My thinking is it could be a better bet for planted tanks than Nitrate test kits. I assume it would need a bit of experimentation to find an indicator...

    Tap Water or RO

    Slugs can be a problem with rain water butts. A band of anti fouling paint is a good deterrent. I pump rain water from the collector butt to storage butts with covers. I use about 15 gals per week and have yet to run out. (approx 30 gal water change) A hard winter may be a challenge. Have...

    Inline uv

    Welcome to the forum. The answer is: Yes and No. Inline (the bigger the better) are the only ones that are worthwhile. Its all about 'dwell time' and that depends on flow rate and the power output of the UV device and tank turnover values. Are they a sound investment for the planted tank...

    Rabbit or Guinea pig droppings as fertiliser

    Hi Ray, yes is the simple answer. Never liked the idea of a cold stagnant substrate. Also UG is a first rate pre-filter for an external canister. I just EI dose the water column and away they go.

    Sheep poo was also used, but typically the fish kept were live bearers and as tough as old boots. Best to use 'pure' chemicals and follow the EI route.

    Day Vs Night setting

    Does this apply to other fish, or is there little or no research on other fish species. What about growlux tank lights and their equivalents in LEDs as used in hydroponics. These match the photosynthesis absorption spectra. Its dim to us but is it dim to plants.
  21. Oldguy

    Day Vs Night setting

    Surely red/blue light is utilised by the plants for photosynthesis, so the photo period is just extended. It may look dim to our eyes because we see better in a yellowish light. To humans a cold light is not as 'bright' as a warm light. I use red/blue LEDs for my 'high noon' lighting for plant...

    Magnesium in tap water

    I requested Mg in ppm from my water company and got a reply in degrees Clark of CaCO3 equivalent. Very useful I don't think.

    Discoloured macro mix . . .

    Magnesium in tap water

    Yes the ratios are a very good fit. I use this ratio with regard to water analysis in general, however tap water can be lower. Bottled water typically comes out of dolomitic limestone. Potassium boost - about 10ppm. IE should be EI Estimated Index. Dyslexia lures KO.

    Iron salts vs chelators

    They are all chelated. The iron ion is covalently bound to the organic ligand(s) and the resulting complex has an ionic change typically balanced by sodium ions. The chelated complex can be directly taken in through cell walls. The chelates have different stabilities to the central ion (in this...

    Epsom salts

    Try for about 0.2ppm, or less, of Fe in your water column for starters. Your stock solution is 252ppm in 100ml so 1ml will delver 2.52ppm if added to 1litre of tank water or 0.252ppm if added to 10litres of tank water. You need to guestimate the net volume of your tank in litres, divided by 10...
