I have this wierd problem. I bought 2 different bags of monopotassium phosphate and made a pretty strong solution with it. (>10gr on 100ml water) Both solutions don't measure any phosphates in it using both my PO4 profi test (drop test) and also not with my Hannah PO4 tester (digital). What...

Question; i have bought an HM digital AP-2 tester to measure my conductivity of my R/O water unit. I want to (only) use R/O for my new tank and i want to get it up to 3.5 Kh. If i look at the manual from Dennerle Remineral+ for example it states: So adding 10g to 100l gives you: 1.3 Kh 2 dGH...

Hi all! In the past I've had multiple aquariums equipped with either sumps and sand filtration or external filters, all of them combined with massive PVC plumbing and 'bored out' AquaMedic 1000 reactors to increase flow. Some even had automatic water change with RO based on water sensors. I...

In the project "The World’s Largest NA Project" Amano used different techniques.for layering the substrate. They start with volcanic rock and fill the gaps with Pumice; I get the part that they want to fill up the gaps in the volcanic rock, like shown in this screenshot; But what confused...

Does anyone of you know if the formula for Sera Mineral Salt changed? I bought the product before to raise both the GH and the kH of my RO water, but now it says on the packaging that it does not affect KH (anymore?). Does anybody know more?

I want to buy a new CO2 regulator, and i am thinking of buying a dual stage regulator while i'm at it. Now i have a few conditions; it must fit a EU CO2 cillinder (DIN477 / W21.8) and it must be powered by a 240v Solenoid. I've found this one, claiming to be a dual stage regulator, but neither...

lately I have lost a lot of amano shrimps. After talking to Chris Lukhaup (who i know personally) on a fair last weekend he told me that the Amano shrimps could suffer from a bacteria, especially since other fish didn't seem to be affected. So yesterday i decided to uproot some plants while...

I was thinking of adding an Eheim Compact+ Marine pump on a seperate inlet for CO2 enrichment. This is a NW pump (venturi style), followed by a clear water filtering housing to increase dwell time and then join the return with the Fluval FX6 output to the main tank. Would this work? Returns...

Please find attached a color spectrum of the lights i currently have. As you can see by the graphic, i can tweak each channel to my likings, resulting in a different spectrum, a different output in Lumen and a different wattage. I also have the possibility to show Clorophyl A, Clorophyl B and...

My container is currently 1000.0mL; i add into 1 mix: - 57g KNO3 - 7g KH2PO4 - 83g K2SO4 - 169g MgSO And i dose 240.0 mL /week (spread across 3 dosages of 80mL) into a 400.0L tank. This gives: - NO3: 21ppm/week - PO4: 2.9ppm/wek - K: 22.3ppm/week - Mg: 10ppm/week If i enter these values at...

So i have Akadama, on some spots i am getting brush algae. Water is injected through a spraybar and it seems that the brush algae is appearing only on the ends of the spray bar where water circulation is less then in the rest of the tank. So you'd think that it is the water circulation but i...

The more i read on this forum, the more i come to understand that in my current tank CO2 and flow are the only fractions i have yet to tune.. So this quote got me thinking; Especially the last sentence of this part is what intrigues me. I think that the reason people advise to improve flow is...

So i have this huge ass lump of driftwood, i think it measures about 25x25 at the base and goes into a mountainy shape. Problem is however, it won't sink! It is in a butt outside with a bag of aquarium sand on top (10kg) to keep it submersed below the water surface and has been so for over a...

Is it possible to attach a CPR overflow to a Fluval FX6 e.g. would it work?

I have a Fluval FX6 attached to my Aqua Medic 1000 reactor (currently still filled with bio balls). I have 2 problems at this moment, but plants are doing great! 1) After cleaning my filter, i always get some bio film (either attached to the bio-balls in the AM1000 reactor or still present in...

So i'll be off wearing my UKAPS shirt to Interzoo this weekend, i'll be there on saturday; anybody else going?

Since when i got my new filter (Fluval FX6) i noticed that my surface skimmer had trouble keeping up. So i needed to increase the throughput of my so called "Oberflächenabsauger" which is German for 'surface extractor'. Without to much of a introduction here are the steps i've done, it took me...

Hello, I hope to write down the information i currently have to help some other customers with the proper GHL products you need to buy in order for dimming Mitras Lightbars with the Profilux. Note; this ONLY applies to configuration 3 like shown here: Mitras Lightbar (configuration 3)...

Well, if all is correct you should see the status of my tank in my signature :) This is done by a cron job which regularly updates the picture based on actual Profilux readings (through a PHP script). If the pH rises above 7.2 i will receive a push notification on my mobile phone. A pH of this...

So i saw one of my Congo's with a Sakura shrimp in his mouth, having his very own Christmas dinner. For that the Sakura are to expensive, so i am searching for a good alternative. Currently my fish stock is: 20x Cory sterbai 100x neon tetra 40x amano shrimp 20x sakura shrimp 12x Congo Tetra (5...

Hey there, Currently thinking about replacing my 2178 (with heater that i don't use due to my T5 HO lamps). Reasons i want it replaced: - i don't use the heater - flow is to little - air builds up every 10 minutes, i think due to the fact that my AM1000 reactor is at the same height as my...

Hello, I went to Interzoo on thursday 17th of May. Here is a picture album with 275 pics (to much to upload here). I also made a video, showcasing the Vortech MPxx pumps, the new GHL Mitras led lightning and other stuff i found on the fair. Sorry that it is mainly thunderstorm, but that is...

Hey there, Anybody still got the Hydrotrix Gardneri in their tanks and is willing to ship to NL using prio UK postal service? Will pay you by paypal all shipping costs + something for the plants. Regards, Gilles

So i have been a bit quiet over here, due to the fact that i was very busy at work and i have worked on my secret project. I've managed to finish my new tank a little over 7 months ago. Specs are: - 180x70x70 plywood tank with glass front - No stabilizers (e.g. i have full movement over the...

Hi guys, Convinced after a talk by Dan that i should register, here is my registration. I am a tech freak and basically DIY almost all my tanks. I will spare you the 5 years of trying to get things right in this post. I will post a log of each of my tanks on the forum, so you know what i did...
