What do you think was different about the new tank that allowed that to happen? I have been debating a chaeto reactor and / or a filter fleece shelf to help with nutrient export, which I think might help?
I deep clean fairly often and am quote diligent with it but it never actually dies back, you know.
Do you recommend vibrant and is supposed to be safe to use all guide ZeoVit due to the different bacteria?

The live rock is the same stuff from before. Nothing new added and is very mature. It has previously been in a high nutrient environment but I did start Zv 9 months ago now; should they not have leached out by now? Same goes for po4 absorbers and kalk - ditched when starting Zv.
Ok so the lighting change was probably about 6 months ago now so hopefully they will be fully adjusted.

The algae grow as they pick up nutrients from your rocks directly. Only way to get this under control is to regular remove the algae with a brush in addition to adding herbivore like snails / urchin which will eat all the shorter algae once if they have been manually removed. Might be a longer process.

Thanks. One area that the algae continues to grow is actually on an inate glazed pottery pot. So that algae is 100% drawing nutrients from the water column. Any advice to further starve it?
Will get myself an urchin and couple more snails though as well this weekend.

Would recommend to remove the pot, the material which it is made from can contain several unwanted substances.

Mespilia globulus and Tripneustes gratilla are excellent algae eater.

Hi,
Update on the tank:
I have added several snails, hermits and an emerald crab. About a month ago I also created a DIY chaeto reactor, to try and combat the GHA and I must say it, coupled with the addition of the new CUC has had an extremely positive effect on combating GHA in the display.
I am now after some advice as my K level is persistently dropping. It is now at 320ppm (was always stable @ 380-400 prior to chaeto).
My stylo is losing PE and all corals have noticeably stunted growth.

I am over due a ZeoVit change (can that affect K?) so I am doing that and I have prepared a WC for today.
How much K-Balance can I add going forward to increase K levels and is there anything else (maybe Iron or Potassium Iodide Flouride?) that I should be adding as well?

Current dosing:
ZS 0.3m daily
ZB 2 drops 2 x weekly
SP 2 drops daily
Xtra 1ml daily
K Balance 2ml approx 3 x daily

Thanks,
Mike

Hello Mike, the zeolite material does not absorb much potassium so there must be another reason. Lets repeat the test first to see if there was any kind of a problem with the test.

To increase the level dose 1.5 ml K-Balance 3 – 4 x daily. Allow a minimum dosing break of two hours between the additions and check the level again after one week.

If your corals doing well expect to increase the potassium level there is not much I would dose at the moment additional. Lets also reduce the XTra dosage to 1.5 ml 2 x weekly.

Thanks G.
I checked the K test against a fresh batch of salt and it tested correctly so I am fairly confident the test is correct.
All corals are doing fine other than stunted growth.
I will take on the new dosing regimen and update in a week or so. Thanks.

Hi,
Tested K two days ago and achieved a reading of 350 so thought I was on the right track but now tested today and got 320.
Coral health is OK, PE on stylo is no longer a problem. But am very concerned that I cannot appear to raise K for some reason...?

Separately - I also just acquired a maxima clam 6cm and it keeps toppling off the rock, tried it on sand and again it toppled over - all during the night. Any suggestions for the clam also?

Thanks again

Old K test kits tend to give lowered readings. You have to ask yourself if the kit is old

Difficult to say what the problem with the clam is, does it open completely while the day ?

Tested a new salt batch and it tested to 350 so perhaps the test kit has gone bad..
No it doesn't open fully- stays fully shut a fair amount of the time.. I'm speculating that it maybe is trying to adjust to the lights?

It can also be some kind of damage but lets hope the best. You can try to place it in a area with lower flow and less light on some kind of a reef plate at the bottom of the tank.

Hi,
So I lost the claim unfortunately - not sure what was wrong in the end.

I have just put a deposit down for a new tank 900x700x500h in mm.
This is upgrading from a 160L gross water volume DT to 315L DT.
In the days immediately prior to the changeover day itself I will do a couple of large water changes and keep the old water heated and circulated, ready to be re-used. I figure this will help to keep some stability for the animals, rather than a sudden massive influx of fresh saltwater; thoughts?

Also are there any recommendations for zeo dosing regime before, during and after this changeover?
I remember reading somewhere that Xtra can be overdosed - what about zeobak etc?

Thanks as always.
Mike

Do you have to transfer any kind of animals to the new system or is there enough time to first cycle the new one before transferring / adding animals ?
