    I suspect that limnophila is a hyper accumulator. It takes in heavy metals easily (like Blyxa Japonica). It's not suppose to, but it does as some sort of "defence" mechanism. When people grow it with excessive dosing it reacts and colours up in all sorts of unnatural shades and people think this...

    Where did you get this idea from? I heard it from a lot of people and I never could see the sense of it considering these people also advocate excess doesn't cause algae. By admitting to this you've indirectly confirm that some fast uptake of whatever nutrients it is, is required. Is that not...

    Planted tank for tetras (slow burn)

    About 2 months in I decided to get 4 Corydoras Duplicareus and 5 Corydoras Concolor to keep my 7 Corydoras Rio Nanay happy. The Rio Nanay corys I never saw during the day time. All they did was come out at night to feed and I had to use a flashlight to see them during the dark hours. By adding...

    Planted tank for tetras (slow burn)

    This was the tank in the early stages and I needed to do a trimming session. As you can see the moss did start to grow on the wood more. Some of the plants were getting out of hand so out came the scissors. I had some Rotola Macranda and I didn't like it that much, but recently it's starting...

    What is causing this algae?

    Yes, Excel will kill it. However if everything remains the same it will come back and you will have to continually dose Excel to keep it in check. This is not really a permanent fix since it requires constant Excel dosing. Delicate plants and mosses do not like Excel at all. Another way is to...

    What is causing this algae?

    What a lot of people don't get is that nutrient toxicity works by the mechanism of relative concentrations. This is the source of the problem, and is the reason that the conclusion of this post is the way it is. This is a very important point that I was only aware of last year, and it was by...

    What is causing this algae?

    I don't have BBA at all. That sounds pretty arrogant, but it's the truth. The reason I don't have it is because I've addressed the source of the cause of it: excessive micro nutrients. It's got nothing to do with organics and everything to do with your water parameters. Hence for a quick...

    Planted tank for tetras (slow burn)

    The major problem with a powerfilter is that it does not lend itself to automation like a roller mat filter. Also having it on the intake of the pump means that as it gets clogged the resistance will increase on the pump and thereby reducing the flow. Hence pump strength needs to be increased...

    Planted tank for tetras (slow burn)

    So what is a PowerFilter? In my planted tank system I initially wanted to have an automated roller mat filter since I like it to be low maintenance. But as luck would have it I was reading some other hobbyist's reefing blog and came upon someone who had an amazing collection of reef tanks that...

    Planted tank for tetras (slow burn)

    Note: There are people on other forums I rather NOT give this information to due to the disgusting way they've had me banned for telling the truth, but in the interests of the hobby and most of the beginners here I'll make it available. What is a PowerFilter? I've mentioned "soft" forcing and...

    Planted tank for tetras (slow burn)

    Here's a recent photo of my syphon box to illustrate some of the points discussed. as you can see I keep my h1 value high, and the water level in the skimmer cup is high. In actual fact because the "U tube" for this syphon box is so large in cross sectional area the water level difference...

    Planted tank for tetras (slow burn)

    Then a good way to achieve that is to do the main tank and sump arrangement IN REVERSE. This is the trick used on the Eheim wet/dry filter. Except they DON'T use control on the pump output. What they do is to have a float that BLOCKS the input hole for the pump when it gets near to it. When...

    Planted tank for tetras (slow burn)

    It ain't my design. I've never had my own design of overflow boxes, just modified what was out there. What are you trying to do? Make waves? Or want to drain and then fill at regular intervals like a tidal pool? Do you want the water level in the tank to fluctuate over time? If the water level...

    Planted tank for tetras (slow burn)

    As an additional note I want to mention Amano's Personal Tank: He's running a sump filter too with a corner overflow box. It's a 60cm box with holes drilled for the three down flow pipes, so no U tubes used. Now looking at some photos of the overflow box in an old ADA 2006 catalogue, I would...

    Planted tank for tetras (slow burn)

    So having said all this we'll go over what Tom Barr did with his setups. Firstly I will state that I got nothing against Tom Barr. I never met him, nor corresponded with him in forums or email. I'm just pointing out the contradiction in the advice he and his "polite" experts (or rather self...

    Planted tank for tetras (slow burn)

    So last diagram is of the overflow box what I'm using. Basically in this design the bracket that connects the skimmer cup and syphon box is the U tube itself. It makes for a neat looking syphon box but is has some drawbacks that we'll get into later on. One of the disadvantages is that it's...

    I wouldn't use excel if I were you. Yes it will kill certain algae but I rather fix the problem than treat the symptoms. I don't like it because it's toxic stuff and doesn't need to be in the tank. It's also marketed as a alternative carbon source. Blackout usually only work for BGA and won't do...

    Aquascaper 600

    Float valve with pressure solenoid as used in under sink units. That's the easiest way to do it and literally idiot proof. Why did you do a black out? Was it for BGA?

    Aquascaper 600

    It's not a question of changing your mind. I'm trying to tell you what the issues are and how unusual it is for someone to contemplate running a 800 gpd RO system. I have no experience in doing such a thing but would guess that there might be a lower quality of RO water produced since it's going...

    Aquascaper 600

    If you're running a window cleaning or a car wash business I would say go for it. 800 gpd is phenomenal!!! It really is. Hardly any fish keeper would want such a powerful unit unless he's running a 2000+ litre tank and needs to change the water really quickly!! Also if you're going to run DI...
