370 mg will not cause issues but keep a eye on it, it should not decrease furthermore. I would recommend to keep it at 380 mg if you already own a supplement. Make sure to increase it slow.

The sand will be helpful but as you already mention the rock quantity is minimal so I would put some additional live rock in the sump.

Hello Rob and welcome to ZeoVit.com !

Dry rocks can also be used from the scratch, the cylce is the same as live rock it just takes much more time, up to a couple of month before the biology is solid. Using live rock does speed up this process massive. Personally I prefer live rock but...

Many had issues with live sand in combination with ZeoVit. They had constant cyano and other kind of films on the sand. The situation has changed when the sand was replaced with dry sand. My recommendation is also to use a shallow sand bed of 3 – 4 cm depth with aragonite in the grain size of 2 –...

To me it looks like your dry rocks do leach PO4, not sure if you have checked this before adding it to the system. As you do not have animals in the system already it might make sense to use a PO4 absorber temporary to get the PO4 under control, otherwise all you can do is wait until the level does...

Some coals do enjoy more flow others less. I had a water movement of about 35 – 40 x in my systems which has worked fine for all kind of corals. The more the corals have grown out the more flow is necessary as the coals do lower the flow but 100 x sounds a little bit to much for me.

I would add a couple of herbivore like snails and remove the algae with a tooth brush manually regular if they grow back. You can dose 2 ml CoralSnow / 25 US gallons every other day additional for some time to support this process. As long as the algae do grow I would not recommend to dose the additional...

More flow does not cause issues if the sand is not blown away and the corals are not placed to close to the stream of the pumps.

You can also start with a lower amount of the material, just make sure to also adjust the reactor flow to the actual used quantity. Recommended flow is 400 liters per hour for each 1 liter ZeoVit material. Use also the 3 hour on / off interval for the reactor for the first couple of weeks.

Hello Alex, I would recommend to contact the manufacturer via e-mail (info AT korallen-zucht.de)

Congratulations, corals are looking healthy with good growth. Keep a eye on the Caulastrea coral, they can get very long tentacles while the night damaging other corals around it.

Hello Amy, using the old water is just a small piece of a cycling process. You need to first cycle the new system as described over here:

While the cycle process you can add some sand and rocks also some of the old ZeoVit...

As the net water volume has changed since Jackies dosing recommendation I would recommend to continue as follows:

1. Continue to use 0.8 liters zeovit in a Zeo Reactor. Water flow around 80 US gallons per hour. Connect the reactor pump to a clock timer and run the reactor pump with a 3...

Not sure about the actual fish load but basically if it is to high it might be difficult. You can try to feed the fish more targeted that no food is drifting through the rockwork. Additional you can try to vacuum the sand while each water change to remove the sediments form the deeper sand layers. Also...

What about a small hangon filter with some DIY basket to hold and clean the material ?

From the product description the Coral System does contain all necessary elements and if you are pleased with coral coloration and growth I would recommend to stay with the products you already use. Do you like to improve anything ?
