Tunze Comline pump 0.900

Hi,

Does anyone use this pump? Can it be use or strong enough as return pump for 8-10g nano ios tank :hmm2:?

I am not familiar with that tank. The pump has a maximum head pressure of 26" and a maximum flow of 225 gal/hr. It would work well for a small built in filter but not for a sump type set up below the tank.

Hi rvitko,

Thanks for your reply.

Actually It's a nano "All In One build" frag tank (sump/overflow behind the tank).

Tank dimension is L17xW13xH8" (7.5 gal) with additional overflow compartment of 3" behind. Due to small overflow compartment (L3xW13xH8", 1.5gal) limitation, thought of using this low watt 900 as a return pump to minimize the heat generated in the small tank without any wavemaker...:fun2:!

My calculation is 225gal/hr is more than 20x of my overall tank gallon that should be sufficient to create some wave inside the tank itself :dance: but the max head loss of 0.7m is my worry....:sad1:!

What do you think :debi:?

It couldn't produce a wave as it is not controllable. 225gal/hr is with no head pressure and we have to expect some resistance from tubing and elbows but my best guess is from the back compartment to the front, maybe 12" of tubing and one elbow, the flow will be at least 150 gal/hr and it is adjustable down if needed. It should work.

Wow, 150l/h is more than sufficient as I am expecting slightly more than 100l/h :dance:. I don't need strong wave but good circulating flow will do as this is a just small frag tank :bounce3:.

Thanks again.
