I wouldnt get too hung up about the dechlorinator, US and UK measurements are not all that critical when talking about the volume in an average fish tank. A couple of drops is fine, you would be hard pressed to overdose....!!!!

I breed shrimps and occasionally see Planaria which in a shrimp tank this is bad news - I use this stuff from Benebachi which works great and no harm to the shrimp.

Boots household Ammonia has always worked for me. If you have another source of fully cycled filter media, give this a squeeze into your new tank, looks pretty bad but it seeds the process with billions of bacteria and really speeds things up. I can fully cycle a tank in 10 days using the Squeeze and Ammonia method. Just make sure you do a 90% water change and clean up all the muck from the squeeze. You can add a full bio-load of fish immediately but it you only add a few initially there will be a die-back of bacteria and you will need to introduce fish in small doses thereafter to allow the bacteria to catch up again with the increased bio-load.

I reared hundreds of Angels in the past and always removed the eggs to a home made egg tumbler, after hatching I transfer to a small rearing tank with a small fully cycled sponge filter.
I have rarely had success with dried foods as in my experience the young angels react to a "moving target" in the form of live foods - I prefer to use Microworm as this for me anyway is much easier than preparing BBS. Im sure there are several methods of success but this is simply how I do it.

Hope it helps.

I concur what Noodle has said. Im my opinion you have 2 choices both of which require meds. You can continue with the recommended dosing regime of your current meds and see if you can kill off the secondary stage of the cysts hatching - or - add carbon to your filter to remove all traces of the existing meds, remove the carbon and do a full spectrum treatment with eSHa Exit AND eSHa 2000 - when used together they are a very powerful treatment that will kill off almost any known infection. Your water will turn Green for a few days but thats just the colouring in the meds and nothing to be alarmed about. Once the treatment cycle has been completed and all traces of Ich are gone you can add fresh carbon to remove the residual meds.

Hope this helps but you need to act NOW to prevent any further fish distress which in turn can lead to infection outbreaks.

Take your filter media out of your current setup and literally squeeze it, or wash it in the new setup (make sure there is tank water and fresh dechlorinated water in the new setup)it wont look pretty but this is the most effective way of "seeding" your new filter. Just make sure that you continue to dose your new setup with Ammonia to 5ppm as and when it drops to 0ppm - just follow the fishless cycle process.

They will be fine in whatever you have at present. If however you are not happy with that, try using simple inert fine black gravel, looks great when the cherries are in breeding colour and sets off the Greens of your plants.

Just a quick note of caution however, make sure you remove all livestock from your tank before disturbing the existing substrate, if this hasnt been cleaned regularly then trapped toxins will have accumulated and will be released into the water column - this can in itself trigger a mini cycle resulting in loss of livestock.

Check also for any NitrIte spike that may follow, the ammonia levels now dropping would suggest the beneficial bacteria begining to multiply and munch it out however there will be a naturally occuring Nitrite spike as waste matter from your Ammonia munching bacteria, it is unlikely that the Nitrite munching bacteria will have caught up with the spike.

I have not personally used this brand of substrate but I have used other similar products such as ADA Amazonia and Amazonia II in my Crystal Red/Black tanks and YOU DO NEED TO CYCLE the tank first - the Amonia is being released and thus a cycle begins so be very careful to check stats before adding livestock. This substrate is good for Shrimp species that prefer a softer more acidic environment - Your Cherries are prectically bomb proof and do not require any specific conditions, doing well in both Acidic an Alkaline conditions.

Hope this helps
