sump building

making a DIY 10 gall sump to a 29gall tall DT. looking for advice on the IB/OB diameter of the flex tube, needs to travel about 30 inches to the sump. trying to limit flow to under 300GPH.

i would use PVC personally and when building the return T off back to the skimmer section of the sump on the part heading back to the skimmer add a ball valve and choke it off there to regulate the flow to the tank.. this gives you control and you can tune it in as you need or want.. dependent on your set up i personally would use 1/2 inch or 3/4 inch for this set up due to the size of the sump... again thats just me...

i like the idea of PVC, just heard its a pain to clean. if i use this return flow do i need to create a siphon break: Aquarium Plumbing: Directional U-Tube

or should i just build my own return????? seems easy

a siphon break is for your protection... i would always recommend one on the plumbing.. as for making your own i would but then i hate spending money on things i can make cheaper... this can be made for under $3 and no shipping LOL

thanks for the advice and i have decided to spend about 20$ for plumbing, much cheaper DIY. so last question on the fuge, do you recommend using a clip on fixture with high wattage bulb or florescent light?

ok what i have read about and chose for myself.... is a clip on with a CFL (spiral bulb) inthe 5500k (color temp) its about 13 watts and once things are stable and going when you add the cheato it grows like crazy under that light... i pull out about a gallon zip bag full every 2-3 weeks and leave about a half bag in the sump!!!!! the 6500k surprisingly grows this a bit slower and therefore not as productive as a nutrient export.....
that said i have seem others use a good grow light (floro) in the 6500k range and get good results.. but under normal light there is reportedly no or very little growth...... again though you want to wait for about 2-3 months after initial set up to bother with the cheato so it has waste to remove... (my first batch went in at 4 weeks and died in 3 days!!) after i waited i have not had to by any more
