Re: 'Under the forest canopy' - 03/04/08 Update with pics
This is the maxijet MP400 I bought from aquatics online for £15ish for my 125Ltr. I would suggest that it shouldn't be used on tanks any smaller than this as it is very powerful even with the diminished flow rate caused by the holes. It will probably work for anything up to 300Ltr
This is a pic of the pump
A pic of the impellor which I have since widened the holes to 1.5mm with a normal cordless drill. This pic has some .8mm holes I made in it.
A pic of the CO2 line fed through the intake housing
And a pic of the pump hidden behind the red lotus
You can just see it in the reflection on the left hand side
CO2 needs to be lowered when using this because with a disc you get backward pressure reducing the bubble rate. With this method there is no backward rate and I found that the bubble rate increased. Also as it seems to work much better the ppm is reached earlier.
As a guide I went from 60-75bpm down to 28-30bpm to still reach green in the DC
