How a seawater aquarium is created Part 20: Cyanobacteria, fully caught!

01.11.2018

Of course, we are not immune to plagues. Immediately after the diatoms that are typical during the run-in, the whole thing quickly turned a rich red - we had cyanobacteria! First the bottom, a short time later the stones too. And it was quite an agile form, according to an examination by Mrutzek Meeresaquaristik. Here we show you the measures we took.

We had a visit from Aquaristik Singer from the Upper Palatinate at the beginning of August. did a super great aqua tour. Among other things, we were at Reef-Corner in Belgium, Korallen Basler (Eschweiler) and Meerwasser Böttcher (Bergheim). (Bergheim). It was a super great day, during which we, but also the "Singers", bought quite a few animals.

It was already foreseeable that the brown coatings would turn into red coatings. red coatings. But we didn't know for sure until mid-August.

Now good advice was expensive! Despite all the articles we have on the subject of cyanobacteria are available here on our coral reef.com. Before we always had the 30.08 in the neck because we "had" to go away for 10 days on holiday. "had to". (Cancellation was no longer possible without high costs)

What we have not tried everything to get the red coatings under control. get a grip on. Keep the phosphate value at 0.03 mg/L every day with Phosphor Plus, IOD increased to 0.06 - 0.08. Various adsorbers in and out, water analysis etc.

When it got worse and worse and we really had to siphon every day, we turned off the light for three days. After that it was quiet for two days and started all over again. We then started to add more bacteria to the tank with Rebiotic from FaunaMarin. to add more bacteria to the tank. Just at this time the new Fauna Marin RED X came onto the market, which we then also used.

Here now is the video the video that we made in three parts.

In addition to the above-mentioned remedy, there are other preparations on the market. For example, Aquaconnect offers Cyano Remove and Korallen-zucht.de offers Cyano Clean. We advise against using products from abroad, as they may contain antibiotics. This simply has no place in the aquarium and waste water.

Before using the products, you can put a few things to the personal test:

1. Do not introduce silicate into the water (good reverse osmosis system and mixed-bed resin filter).

2. check the water values (even with 0 phosphate, nitrite and nitrate, the cyanos grow magnificently. the cyanos grow magnificently! Conclusion: with these values nothing else, i.e. competing algae, bacteria, etc., can grow! etc. grow!!!) Especially in the beautiful SPS tanks, which are kept nutrient-poor tanks, I hear again and again that cyanosis occurs. Cyanos appear.

3. salt change (towards the end of the run-in phase I briefly had cyanos. Cyanos, I suspect they are part of the process. After a After a salt change, the few deposits disappeared)

4. UVC (works great for me, but I only use it intermittently, because it also prevents the growth of other bacteria and algae.

5. phytoplankton (living it is a competition to the cynos and the corals and the zooplankton are happy)

6. carbon filtration (helps to remove the pollutants of the cyanos, the fish and other the fish and other inhabitants such as snails, hermits etc. become fitter again. become fitter again in case of a heavy infestation of cyanos)

7. regular water changes are better than having to replace 50% of the water in an emergency!

8. oxygen (especially in the cold season the cyanos seem to like it better that there is less aeration) cyanosis seem to like it better that there is less aeration and more nitrogen in the water. is introduced into the water)

9. light (every now and then you have to change the lamps in T5 and HQI, If cyanos appear, there must be something else wrong with the biology of the tank) I no longer do any of the much praised dark cures any more. Everything else suffers from it just as much as the cyanos and it will not change the cause of the plaque.

Further information on this subject will be given in the next part :-)
