How often do you need to recharge it? Is one enough for a 75 gallon?

I recharge mine when it turns brown like weak tea color. 1 should be enough depending on the biological load. If you have protein skimmer it should last 4-6 months between recharging

It really depends on the length of the burst that you use. We tend to use a two or three second burst every five minutes, and the tank lasts a LONG time. We have been running it for several hours every other weekend for the past several months, and it's just now below half full...

Mine usually runs for 10-12 before I refill it. It's going to depend on the level of saturation you put it to.

I've found that a 100-120 watt solar panel will be able to recharge this system from empty to 80-90% full in a good sunny day's worth of sun. It takes the full day to do it and if it's cloudy or worse then expect 2-3 days depending on conditions. You will need to add a solar charge controller to help with the task and to protect the battery from being over charged.

It all depends what you have in the tank! If it's a reef, you would want the tank cycled minimum 10x per hour. If you have freshwater with no live plants, then typically 4-5x is plenty.

Just inserted four rechargeable duracell batteries and it works just fine. Just like B. Conner said, it doesn't take much to run that small pump. I think it's most likely a gimmick to just buy and buy regular batteries, which is such a waste of money and so bad for the environment.

I bought it in July 2014 and have not replaced the batteries yet. But I do not run it all the time just occasionally. I have a water barrel with few goldfish in it and just run it for about 30 min. at a time, maybe twice a week. Hope that helps some.

It depends on what you are trying to grow in the tank. Also with one you will be running it at 100% power which will shorten the life. I ran one on my 75 temporarily and it appeared to be enough to grow leathers and other softies but there were lots of dark spots. I now run two at 60% on it with excellent results. But again, it all depends on what your intentions are.

There are a few varibles to consider. The size of your safe, location, how often is it opened. My own personal experience is that I recharge mine about once a month.

I believe you gotta charge it for at least an hour if but I was impatient and only went for half. I have already done three paintings with probably 40 hours down in total. Used it for days and still haven't found the need to recharge. If I can recall correctly, it was mentioned that one full charge should last up to 800 hours.

depends on the usage. I use mine for about 30 minutes everyday. i only recharge it about once a week

Just one. I found I get about 1 hr. 15 continuous use. I don't use it this way, so usually get about a week of on/off use. FYI my first lasted about a year and without warning It would'nt take a charge.Because I'm generally pleased witth it replaced it without any hesitation.

That's almost like asking how many licks does it take to get to the center of a tootsie roll pop. I have never seen documentation or anything stating how many recharges you can do on this unit. I'm sure it will depend on the quality of battery stored inside the case and how well it is maintained. I do recall it stating in the manual that it should be charged every month. I've had a couple of these and one failed fairly soon while the other keeps going. I bought a Stanley unit to replace the one that failed and will soon be replacing my other Peak with a Stanley, its all about quality.

Just to kinda help you out. I have a 75 gallon aquarium. I also have a fluval 406 canister filter. I use 2 350ml of purigen and it last for 6-7 months. It's not specific to gallons. It's based on how cloudy/discolored/dirty your tank is. 2 bags of 100ml would last me maybe 2 months.

It all depends on usage. I would guess using it 4-5 times week, the tank would last around 6 months.

Hi ValerieYou can gat one and one half to almost two gallons of milk per charge. The unit fully charges back up in approx. one hour. I have been using my vacuum milkier for over four years and have not had to change the rechargeable batteries. I expect many more years of use
