not too sure but from what i read on other aquarium forums, there are different grades of glass used for aquariums(higher vs lower iron content). unless yours is crystal glass/some of the higher grade glass with a lower iron content, some of the more regular options have a tinge of green to them.

depends on your fish stocking. if you’re only keeping tropical species you don’t need a chiller. but having one definitely helps overall tank stability by regulating the temperature which means less stress on your fish. if you’re keeping coldwater species that require temperatures below 25 degrees then it’s a no-brainer; you definitely need a chiller. P.S. currently running a semi-outdoor fowlr 4x2.5x2.5ft tank with a sump without a chiller. lowest temp was in the 27deg C range, highest was in the 30deg C range. Usually hovers at an average of 29deg C. from what i know about the uv you’re referring to, the ones ‘exposed’ and placed in the sump don’t require a feed pump, but aren’t as efficient as the ones that do and you can’t exactly control the flowrate in the sump as easily as if it were a uv steriliser unit with flow from a separate pump going directly through an inlet and outlet which forces the water volume to pass through it rather than around it making it generally more effective at doing its job. hope this helps Sent from Singapore Reef Club mobile app

personally i’d go for a 1/2 hp chiller. hailea hs-90 is a decent affordable option imo Sent from Singapore Reef Club mobile app

Hi, i have a large single head pink tip luminous green torch for trade. Looking to trade for hammers.. Whatsapp me at 910six393four to discuss!

Thanks for the inputs. Leaning toward the Kamoer X2S. On top of the 2 dosing pumps, it has an ATO, similiar to the AutoAqua. The downside of AutoAqua is that it depends on the set distance between the 2 optical sensors. Having that in sump, if I do say a 15% water change, the water level in sump drops, whilst the pumps continue operation. Eventually that water volume drops to a point where there is no return flow to tank and no overflow back to sump? A little unsure on how that works out. Just placed an order for the Kamoer. Hope that works out! Else you will see me posting on marketplace soon. https://www.theaquariumsolution.com/product/8258/371

Congrats on thinking about an AWC it would imho certainly improve the quality of your tank, however there are a few things to consider with both options You said about relying on sensors, well the Autoaqua smart AWC has an additional timer safety feature so it won't overrun hence not reliant on sensors alone. The good point about the use of float sensors as the primary control is that they allows the system to replace exactly what it pulls out irrespective of what pumps you use for either input or output, so there is no need to calibrate pumps to match volumes. (I believe autoaqua also offers additonal plug version so you can use higher power pumps as needed but I think those small pumps are surprisingly strong) By Neptune/Kamoer I assume you mean a dosing pump system like the neptune dos, ghl maxi or a 4 head dosers as opposed to an aquarium controller (neptune apex) and dosing pump setup, as they aren't cost comparative. Obviously a controller could do all this and much much more.. which is something to consider if you were going down that path anyways. A dosing pump setup only really uses a timer so you have less safety features in unlikely event anything goes wrong. With a doser you will have to semi regularily calibrate the dosing heads to draw and expel water at same volume to avoid a salinity drift over time. Further you need to avoid activating the ATO (Oh that reminds me, you will still need to have a seperate ATO with this option). Furthermore unless you have a large headed system or continuous dosing pump (like versa) the normal dosers aren't really designed for large volume migrations. That said I used a cheap Jebao doser doing awc for years and it worked just fine (two heads for output and two for input to avoid any issue if a head wasn't calibrated, and loads of little changes every 30-45mins to avoid the ATO triggering) That said, both options have other benefits. The Auto aqua AWC also acts as an ATO system so you save money by not getting a seperate ato (or selling your current one haha) whilst a quality doser obviously can also be used for adding supplements if you have spare heads. Personally I have always liked the look of the autoaqua system, and think it is well thought out little system. But it is costly so I saved my pennies and got a controller instead. Good luck. Let us know what you decide to go with. Sent from Singapore Reef Club mobile app
