Hi,
I'd like to suggest that members break long posts up into paragraphs so that they are easier to read and understand.
I've borrowed the follow post as an example of what I'm talking about:
ive been looking at the same sort of tanks that are used on the moving bed filters so i can get ideas to make one myself,the tanks im looking at using for it are from duraplas (the r1130) model which is 1130 litres in size .this model would keep the size down in its diameter for floor space,one of these 80% to 90% filled with the k1 media should handle this system using a venturi to introduce air into the filter as due to its depth a big blower would be required (more power too).also the flow rate should be at least 9000 to 10000 ltres per hour so hoping that could do the job.as im still working out the exact tanks to use for my floor space,im aiming at a total of say 8000 ltrs maximum for this system so that i can have plenty of workspace and filter space.so if i aimed at the 50kg per 1000ltr of water id be working for an output of say 350kgs (allowing 1000ltrs for fingerlings) and feed rate being 1.5% of weight fed would put a maximum strain of 5.25 kgs on the bio filter.that being the maximum aim point but if densities go higher ,then this would be where id like the biofilter to cope with say 10kg of feed per day.but this also has to be taken into account that there will more than likely never be this load due to at least 2 tanks which could be at different grow out stages to have a rotation happening and not be forced to harvest all at once.if i went to grow them out to a heavier 2kg/3kg (2 year) harvest weight then i could end up with this load on the system.maybe id need 2 of the above tanks for my moving bed?
If we break introduce a few paragraphs, it looks like this:

As you can see, it's already easier to get your eyes around.
If I take it one step further and punctuate it a bit:

This post, and others like it, contain interesting information......and are widely read by members.
My purpose is not to embarrass anyone (thanks for the use of your post, DTD) but to illustrate the difference it can make when it comes to reading and understanding the material.
