Help me choose a Tunze set for a 340g tank

[NexDog]

My tank is 72x30x32 and I'm giving it a makeover. Stage 1 is redoing the rockwork, stage 2 is adding Tunzes. CL pumps broke, Vortechs never worked properly, so Tunze it is. Want enough flow to handle SPS if I ever decide to give SPS a shot again. I can always add more later. Cost is an issue so don't be recommending the $700 model. :bum:

I'm thinking 4 of these:

Or 4 of these:

Or a mix of those and maybe 2 of these:

Any input would be appreciated!

If you are going for non controllable, I would use 4 of the 6125s

I'd try one out and se if you like it. Lot's of second hands available.

I never did a closed loop because you are just asking for problems and depreciating tank and buying lots of things with no sell value. Tunze and controller are simple and effective.

Might only cost a little more than total cost of drilling, fittings, pumps, ect.
