Hi all,
thank you very much for the latest compliments.
DuncanUK:
Its more than 40cm in Diameter (about 16") and a little higher than half of a sphere.
Moser: I've had some Cyanobacteria issues in the past.
We came to the conclusion, that using my modified version of that Balling/Randys 2part etc. method to supply Ca/Mg/KH brings way to much traceelements/heavy metals into the reef. I changed that (not adding "NaCl free seasalt anymore).
I did lots of waterchanges to rinse the system.
I think that, in this system, changing up to 350 liters a week (no traceelement additions) adds more color to the coral, changing more than that feels save to prevent ion-displacements due to chemical addings.
Now I change 500 liters a week which is compared to the netto volume of the tank about 20%.
The 500 liter comes from a easy handling thought. If I have too much work with waterchanges I tend to "forget" them.
My work with that is now:
- press button to fill 500 liter container with RODI water (with is refilled (level probe))
- drop one 20 kilogram sack of TM Salt into it.
- wait a week with water moving inside the container.
- press another button (500 liters water runs into the maintank, old water is flowing into the sink.
- start from the beginning.
thats quite easy to do (pressing 2 buttons, dropping one sack). no measuring etc...
viorel:
great what you did there.
Do you use less blue-ish light (more yellow) or is it just the photos?
Interesting, how different the coralcolor looks with this. A lot more red-ish colors. I recently added some few pink-ish bulbs, which pushes colors, I've not seen in there before.

Thanks a lot, I have mostly egoistic reasons to do so ;-)
Thanks again for your kind words,
It really helps facing larger changes and cleaningwork.
Best,
Ralf
Ralf, can you stop at 870? We have had some discussion about cutting a hole in the dining room/kitchen wall and building a big tank in between the rooms. This would involve major construction and expense going to such a large tank. I think I would cut a hole in the roof as well and use a skylight to light the tank during the day.
Right now we are working on putting solar power on the roof... trying to cut down on my power bill!

Hi Ralf,
Really impressive tank which you have!!
One Question do you have the wave modus running in your Tank?
Thanks Ralf,
Do you ever check Dkh of the new water before you put it in the system?.
I do the same, but check kh now as I've had a couple of buckets measure only 4.
I switched to bioactif recently. It's a great salt. It gives a really crystal clear water column for a few days after every change.

Amazing
Hi Mo,
upps, haven't done that.
I check the tank after the water change to correct sg, KH, Ca, Mg.
But yes you're right, I'll have a look at it next time.
Btw. Salt demixes due to gravity, small particles wiggling through the big ones down. So if your 4 DKH salt was standing for some time without mixing the dry salt afterwards, this could be one reason?
I haven't tried bioactif and you are the 2nd one recommending it to me... hmm, think I'll try it with 2-3 water changes in the future.
I usually buy a pallet of salt with about 800kgs, thats 40 weeks water changes, so "changing salt" ideas seldom show up.
Thanks for the hint,
Ralf
Thats is a fantastic reef and an inspiration for all of us, Im working in a 260g reef and Im using all your experiences and tips for my build.
What has been the most difficult and challenging for you?
Thanks for sharing
Thank you very much,Tank looks stunning Ralf! :thumbsup:
