I am a new member to this forum and would really appreciate any help I can get from the many knowledgeable members here.
Before I start listing some of my queries/concerns, here is a bit of background and the rational I have followed to date:
I have recently (2 weeks ago) started an iwagumi styled aquarium. I am using 9 hakkai styled rocks to build the scape. The substrate used is ADA's amazonia black and I have also used other ADA products such as penac P and W, bacter 100 etc. I have an Ehiem filter which is more than sufficient for the current volume of water held by my aquarium, I believe. Of course, there is also Co2 setup and ready.
I have decided to try and use the fishless cycle during the beginning phases. I am currently trying to grow HC cuba.
I know that ADA substrate is usually rich in nutrients to begin with and that the initial setup phase will provide higher ammonia levels. Because of this, I have been dosing the tank with good amounts of K daily and also been using green bacter to help whenever I do water changes. The first week I did daily water changes and starting the 2nd week I have been doing a water change every 2-3 days. I have been feeding the aquarium Co2 and light daily with 5 hrs on the first 2 days and then 6 hrs daily up until now.
So far, I've noticed a few things after two weeks. The HC cuba went through a period of yellowing and going transparent within 3 days but has since experienced a slow rebound. They seem to be taking root and new leaves are growing out. No carpeting affect at this point as I speak.
Algae control has been alright as well. Since less frequent water changes began I have noticed spots of algae on the aquarium itself but nothing serious.
So here are my queries:
1. Am I dosing the right amount of ferts right now? I am using nothing but Brighty K for potassium and green bacter.
2. Am I growing the HC cuba correctly? I'm not sure why the HC died in the beginning and I'm also not sure why it's taking so long to come back to life. I must be doing something wrong?
Is the 6 hrs of light and Co2 enough for now? I plan to keep the lighting and Co2 levels to be similar and gradually make my way up to 8-10 hrs per day permanently (but with the introduction of algae eating shrimp and fish first).
I've also factored into account that the slow growth may be due to the fact that the temperature in my aquarium is around 29 - 31C. Will HC Cuba indeed completely stop growing at once if above 28C? If this is the problem, what kind of cooling unit should I use or are there other methods to help growth?
3. My final query is to do with fish. When should the fishless cycle end? Should I be adding algae eating fish or shrimp into my tank yet because there are some signs of algae? Or should I be waiting for the HC cuba to grow out more first before I do anything?
Many thanks ahead for any one who has willingly read a long post and am willing to help out with some insight!
