IMO it is better to just give a summary of what is displayed in any links to make your point, cause personally, I find that I lose my link back to the forum if I click on the links.....

Well my computer just opens up another tab, thus I didn't think about that. Also I don't have time to read it and process at this time. At a later time I will do so.

Thanks for the favour, but just wondering how you can direct us to a topic which you have not yet read, in order to state your point... Just curious.

do you mean under 10g and over 30g

Sorry.... I plead guilty here.... Did not read the link..... You've lost me.

in tanks under 10gallons, more light is needed to achieve a suitable level for growing plants due to the minimum light thresh hold (the link given). In tanks over 30g, the WPG rule becomes more leanient resulting in less light needed. For example

50w in 50g tank = 1WPG although this is going to be hiigher and more likely to be 1.2WPG - fine for growing plants like anubias and bolbitis etc

1.2w in 1g tank = 1.2WOG (same as above, but smaller tank), now due to the minimum light threshold, this is extremely low light and plants like anubias would struggle more so.

just a tip, right click on the link, and click open new window or tab.

A PAR meter will tell you how much light is getting to your plants. Anything else is a generalisation. Rex will realise this.

I meant I had read the info but didn't have time to analyze it and make a synapse of it to post. It seemed like great advise to me. For I thought there has to be a another way to figure out how much light the plants needs, without expensive equipment. Just going by gallons doesn't make sense to me for there are 20 gallon long and 20 gallon deep tanks.

It is good that you are reading about the hobby. However, if you use the search function, you will find that we have discussed WPG in detail in this section. There are pages of them. Some of these are very in depth discussions on this topic with experts like Tom Barr and George Farmer participating, and current members contributing as well.
