I have a tub of Seachem Equilibrium and an existing GH of 6, is there any point in dosing this stuff? I only ask because I'm switching back to EI after a couple years of TPN+ and I keep reading about people dosing GH Booster as well as the nutrient calculator I am using saying I should dose GH...

Great work on the B12 link, although that is just one factor, no more or less important than organics (humic acid) and ammonia. Putting nutrients to one side, I would like to bring up environmental parameters that are known to effect BBA, such as temperature and light. Assuming BBA is...

My CO2 reactor rattles :x I've fixed it by using Vaseline :shifty: Unfortunately, the rattling returns after a few days :( Is there a lubricant that is non toxic and will stay where I put it despite water flowing passed at 1500lph?

I planted a load of Echinodorus Tenellus last week. It's quite tall. Tomorrow I will trim it for the first time but I don't know how much. Apparently it will grow better if I trim it short but just how short? I don't want to kill it! Any help much appreciated...

I have purigen, carbon and phosguard. Can I put these into one bag? At the moment I have 3 bags which seems pointless since it's just reducing flow.

Will clown loaches eat shrimp? Since their favourite food is, apparently brine shrimp then I am suspecting the answer is yes but if this is the case, do they eat all types of shrimp?

I will be doing 50% water changes weekly. This amounts to 150 litres so I am looking for the cheapest way to remove chlorine/chloramines from the water. Plan A is to fill up my bath tub! It doesn't get used for anything. My question is how long approximately, would it take for chlorine to...

I've just setup a 350litre Jewel with Powersand and Amazonia. My question is how to get this setup ready for planting. I've heard that Amazonia takes a few weeks until it stops leaching ammonia. I am in no rush, so my plan was to leave it 3-4 weeks, or until ammonia/nitite is zero. In the...

I have a 180l tank but for a few years now, I've really wanted to upgrade to something like 350l. The problem I have is that my living room is on the middle floor of a 3 story house, so my tank sits on floorboards that are supported by joists. I am worried that the tank will fall through the...

I am reading the EI article on this site. This essentially says that if a plant requires 1ppm per day, then all that is required is that you have at least 1ppm in your tank and the plant won't have any problems. So how does concentration fit into this? Let's say you have 2 identical tanks...

I have searched through many internet resources and still can't identify this diatom for certain. It's all over my christmas tree moss :( If anyone can help, it would be much appreciated :thumbup: This last picture looks like a side on view as the diatom is, or has just reproduced.

One of the great unknowns in the hobby, it's anonymous so be honest people and we should get a good feel for the sacrifice our fishy friends have made to the cause :cry:

I have an Echinodorus Osirus. From the shop, leaf length compared to stem was about 30%/70% respectively. It's been running for 2 weeks in my new high light+co2 setup. The new leaves that have appeared are more like 60/40 and double the size, this is considerably different. Every leaf has had...

It's looking more and more like I've had a Ca deficiency issue. Not entirely sure yet but since I have an army of snails in my external filter, I wondered if this could be where all my Ca is going? GH is 9

I've been trying to get my head round this study... http://www.plantsci.cam.ac.uk/Haseloff/ ... aham86.pdf It studies the effect of light intensity, photoperiod and temperature on the ability of GSA to reproduce. They use Coleochaete Scutata. The conclusion seems to be that neither light...

I've had a image in my head for some time now, involves my tank with a giant rock in the middle, surrounded by grassey stuff with the rock covered in moss. Last week I got around to setting this up and bought some moss balls because well, its called moss, only to discover it's not moss. I don't...
