Lighting Timings And Flow Advice

[yasinullah]

Hi all,

I have a Juwel Vision 180 tank, set up with EI ferts, pressurised CO2 (using a cigarette filter at the moment waiting on up in-line atomiser from Hong Kong to arrive). Also a Tetratec EX1200 and a 2000lph powerhead.


I'd appreciate some advice on timing for lights, 8 hours maximum? should I have a gap in between?


As for flow, I have the filter inlet on the back right corner and about 3/4 down (standard tube inlet). For the outlet I have a spray bar that spans the whole tank (minus 6cm or so on each side).
How should the spray bar be aimed, pointing downwards? with one pointing upwards to give a slight ripple?
The 2000lph powerhead not sure where to position that either, I've put it halfway down the tank on the right hand side.

and here's a paint diagram that probably makes more sense!






many thanks!

In my eyes 2000lph is way to much... but that's just what i think. I had a 1500 in my tank and the pressure was killing all my fry...

oh maybe if I wrap tights round it should slow it down, it doesn't feel all that powerful though I'm not sure what 2000lph should be like!

its this one I've got http/www.ebay.co.uk/itm/Submersible-Home-Aquarium-Fish-Tank-220V-2000L-H-Wave-Maker-Powerhead-Water-Pump-/170899479895?ssPageName=ADME:eRTM:GB:1123

I'd put the powerhead on the left pushing the water back towards the filter inlet so the flow circulates and it is a lot of flow you have there btw but so long as your fish are ok you can never have to much in a planted tank,most people go with 10-20 times per hour full turnover.
