and i thought by having the solution super strong it would immediately turn dark blue...

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...

So yesterday i added 4mg of my R/O minerals to 20l water and got a KH of 1.3 out of it (i use a Salifert KH test) and a μS value of around 169; which is in line with the table above. Would that be a good start? (I have yet to measure the GH value of that water to be honest, see below) p.s. from...

Here is the current setup, with 10 Taiwan Bee and 10 Blue Velvet shrimp. Unfortunately, 2 ottos have already died but my guess would be that is because of the lack of plants. One of my berried bee's: And here are the plants in the CO2 tank, to be transferred to my main tank this week:

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...

Yesterday i hooked up the Thermostat protection device. Basically it is just a relay/switch with a temperature sensor. I have configured it such that below 27 degrees it turns the socket on, and above it it will be turned off. If i then connect the Hydor heater it can never 'boil' my fish in...

Well this is the current setup (with the old light and old (corner) filter); As you can see, quite some surface film already; the surface skimmer on the OUTFLOW (video review of it) also prevents little shrimp to end up in my filter.

As in, not the default Eheim pipes? I was actually planning on using glass pipes as outflow, with a surface skimmer on it, like this one: But this comes with 2 problems: 1) The skimmer can be sucked down if you have to much flow (meaning you have the chance that little fish and shrimp get...

Hi @ScapingScotsman unfortunately that is a 'different' Gilles. I own and operate the Dutch fertilizer webshop, the other Gilles owns and operates the blog and a Belgian fertilizer webshop. However we are named the same which sometimes generates confusion.

Bump.. anybody? In the meantime i've acquired the following (future proof) hardware for the tank: Milwaukee MC122 pH controller 6kg CO2 tank Dennerle CO2 solenoid + non return valve Hydor inline heater 300w (1) AQUARIO Neo Flow In-/Outflow Set Premium + filter guard Twinstar light III 450SA...

Aren't you worried the filter flow would be to much for this tank?

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...
