Thanks @
Irma, How difficult is it to maintain a tank with no sump VS with sump? From what i've read the biggest game changer is water changes and having a larger volume of water.
This is my experience so please note that everyone has different experiences and points of view.
My first tank was a 500L tank with a sump containing the usual stuff and an NP pellet reactor. The tank was awesome! But I had to have someone else do the maintenance because I could not reach the other side of the tank and because of the volume of water that needed replacing. We run on borehole water so an RO unit was not going to work. Plus my sister was not happy with the 'waste' water that would be produced from the unit.
The noise level was also a problem as the tank was in the lounge. This probably could have been sorted out though.
Thirdly, was the stress level. All my own concerns. Our power would fluctuate quite badly and this resulted in the level in the overflow changing. In my mind was always the worry of the tank overflowing which probably would not happen but still it bugged me constantly.
The big plus of this system is the fact that the hardware is hidden away and the sump increases the water volume of your tank which makes it more stable.
I sold this tank and now have a smaller sumpless one. It holds around 330L of water. I have a Deltec MCE600 HOB skimmer which is fantastic. It skims extremely well and as I mentioned, it has a chamber which can hold other media. I do my own maintenance. Once a week I do a 15% water change and I clean the skimmer out every 3 days or so. I do have an Auto Top Up tank sitting in the cabinet which helps keep the maintenance down.
The noise level is almost zero.
More importantly is the lack of stress that I now feel.
Please let me stress that the decision is yours and yours alone.
Do some more research and read as much as you can. I do not want to sway you in any direction.
If you decide to go sumpless then you must get an excellent skimmer and you must keep up with your water changes.
You can also go the sump route - most reefers do it that way and it works perfectly and has many benefits.
