Set minimum speed for mp10?

[mike31154]

TSM has been working well for me on 4 foot tank. I have 3 MP40s, 2 at the ends & one at center back glass. They're in a master/slave grouping but I have the one on the back glass limited to about 50%, not sure, but certainly doesn't ramp up as high as the other two during the mode cycle. My tank is narrow front to back, I would have preferred an MP10 on the back glass, but the MP40 speed limited works well enough. Without the pump on the back glass I would for sure have a lack of flow in the middle. The most quiet places in my tank are at the ends on the bottom & corners.

Occasionally I'll put them into NTM since that's a single button push. I took the time to tune a nice wave when they're in that mode, so works great at stirring things up. Also do that an hour or so before water changes.

What you might consider is changing your MP10 for a 40. Then you'll have more flow at lower settings & the 50% minimum with the MP10 won't be required. You can always limit the maximum speed of the 40 as I'm doing with the one on my back glass.

good call mike using 40s would be the easiest but certainly not the cheapest solution.

i'd have to check first to see if they'd fit in my holes.

I thought you were asking about your marathon pace for 10K. Nevermind, carry on.

judging by the screenshot looks like this might be possible soon?

looks like you have control over the entire output curve =)

Holes? You have holes for your powerheads?

Anyhow, perhaps a trade would be in order, although the MP40 on my back glass where I wanted an MP10 is probably in need of a new wet side, so would be a bad deal for you, depending on the wear & tear on your MP10.

My mp10s are pretty mint I suppose I could search out a trade with cash scenario. I'd be worried the noise would be too much tho. Be a matter of comparing mine at 100% vs an mp40 at something like 50% I imagine.

The holes I'm referring too are the ones in my permanent rock wall which is affixed to the back of the tank.

Trade plus cash was exactly how I downgraded from MP60s to MP40s. I bet there's plenty of people in town who you'd be able to do that with. Used MP40s are selling on RC for anywhere between 330 and 360 bucks, so I bet you wouldn't even have to throw in that much cash.

Each one of my MP40s sounds a bit different. The loudest is the original one I purchased new, the one on the back glass is fairly quiet since it never runs over 50%. The one on my right side glass is very smooth. I've replaced the wet side bearings/washers etc on all 3 of them. I'd be willing to say that any MP40 with a wet side that doesn't have too many miles on it would run fairly quiet up to 50%. Wet side bearing kits aren't too costly, so even a high mileage one can be made to run like new with the investment of a few $$s. Dry side sounds can vary as well though, so you'd have to hear one at 50% & below to see for yourself it would work for you.
