YeW Posted January 17, 2004 Share Posted January 17, 2004 PGR - I would not use an undergravel (can you imagine cleaning the gravel??). I would recommend any of the small power sponge filters. Stuck to the top of the tank near the lids and an air stone to ensure water movement along the continium. Also.. if it is a marine tank I suggest you consult the mariners at MASS . They would know better than us freshies. HTH - Link to comment Share on other sites More sharing options...
Goobz Posted January 17, 2004 Share Posted January 17, 2004 I find filters like a aquaclear is great for a hexagonal tank. Put the biggest one that will fit across one flat and add a few extra extensions to the pick up and it will draw the water from right near the bottom. Just be careful with those tall skinny tanks as they have very little surface area for the volume of water. You will need to put a powerful air pump on it or a powerhead shooting up from the bottom to get the water circulating past the surface more. Otherwise you will find you will have oxygen problems. Especially in a marine tank... Hope this helps... Chris Link to comment Share on other sites More sharing options...

pulse69 Posted January 22, 2004 Share Posted January 22, 2004 they dont like using sponge filters for marine tanks/ they end up being nitrate factories. just use a skimmer and live rock. check out MASA Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 23, 2004 Author Share Posted January 23, 2004 i ordered a aquaclear 500 and were getting some perspex to put at the end to reduce the splashing etc it makes. Link to comment Share on other sites More sharing options...
pipsqeek Posted January 23, 2004 Share Posted January 23, 2004 In my opinion (which is what this forum and others are all about). I would put marine fish in a larger area. Unlike Cichlids, they require more space per fish. They do waste alot (dirty) and you may require a larger filter than normal. Steve Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 23, 2004 Author Share Posted January 23, 2004 his going to put in 2 clown fish as a display and i think some seahorse but im getting him off that idea as they are fussy eaters Link to comment Share on other sites More sharing options...
trofius Posted January 24, 2004 Share Posted January 24, 2004 would it work using an undergravel filter running in reverse from a canister????ie have the clean water from the canister filter coming up through the u/g filter? justa thought..

Link2Hell Posted January 24, 2004 Share Posted January 24, 2004 With the small bio load from a pair of clowns and some seahorses I would use an Ehiem 2213 cannister, available second hand for well under $100 or new with a media pack for just over $120 I think This will last for years, if you want additional biological filtration look at having the return run over a modified bio wheel system or into a container with spreader plate onto bio balls or blue bio foam L2H Link to comment Share on other sites More sharing options...
Zeb Posted January 24, 2004 Share Posted January 24, 2004 I think the aquaclear idea is the best as with a cannister your are having to pump to at least a 3.5 ft head which would decrease the flow considerably, this doesnt affect the hang-on filters. Personally I would look at 2x ac300's with extensions running down to 2ft or so, why 2? One to run to run a denitrating resin and another to run a de-phosphator, the live rock should take care of the filtration and the two filters would add a variety of flow directions (like a rock pool) As for fish, Id stick to the sedentry species, perhap firefish (min of 5) a school of bangai or pyjama cardinals and a scooter blennie to clean up the leftovers. The seahorses will prefer the cooler tank temps so be carefull that he chooses temperate clowns not tropical ones. Good luck, sounds like a great tank Link to comment Share on other sites More sharing options...
PHL Posted January 24, 2004 Share Posted January 24, 2004 I think the aquaclear idea is the best as with a cannister your are having to pump to at least a 3.5 ft head which would decrease the flow considerably, this doesnt affect the hang-on filters. The reason canisters can be so efficient (compared to sumps) is that the head is effectively 0, as you return the water to the same level as you pump it out at (assuming placement of the outlet close to or at the water line). Even more efficient would be to submerge the outlet. The only resistance is the tubing, and moving the water around. Link to comment Share on other sites More sharing options...
